|Stripper, porn actor|
Prostitution is the business or practice of engaging in sexual activity in exchange for payment.   Prostitution is sometimes described as sexual services, commercial sex or, colloquially, hooking. It is sometimes referred to euphemistically as "the world's oldest profession" in the English-speaking world.   A person who works in this field is called a prostitute and is a type of sex worker.
Prostitution occurs in a variety of forms, and its legal status varies from country to country (sometimes from region to region within a given country), ranging from being an enforced or unenforced crime, to unregulated, to a regulated profession. It is one branch of the sex industry, along with pornography, stripping, and erotic dancing. Brothels are establishments specifically dedicated to prostitution. In escort prostitution, the act may take place at the client's residence or hotel room (referred to as out-call), or at the escort's residence or a hotel room rented for the occasion by the escort (in-call). Another form is street prostitution.
There are about 42 million prostitutes in the world, living all over the world (though most of Central Asia, the Middle East and Africa lacks data, studied countries in that large region rank as top sex tourism destinations).  Estimates place the annual revenue generated by prostitution worldwide to be over $100 billion.  The majority of prostitutes are female and have male clients.
The position of prostitution and the law varies widely worldwide, reflecting differing opinions. Some view prostitution as a form of exploitation of or violence against women,  and children,  that helps to create a supply of victims for human trafficking.   Some critics of prostitution as an institution are supporters of the " Nordic model", which decriminalizes the act of selling sex, but makes the purchase of sex illegal. This approach has also been adopted by Canada, Iceland, Ireland,  Northern Ireland, Norway, and France. Others view sex work as a legitimate occupation, whereby a person trades or exchanges sexual acts for money. Amnesty International is one of the notable groups calling for the decriminalization of prostitution. 
Etymology and terminology
Prostitute is derived from the Latin prostituta. Some sources cite the verb as a composition of "pro" meaning "up front" or "forward" and "stituere", defined as "to offer up for sale".  Another explanation is that prostituta is a composition of pro and statuere (to cause to stand, to station, place erect). A literal translation therefore is: "to put up front for sale" or "to place forward". The Online Etymology Dictionary states, "The notion of 'sex for hire' is not inherent in the etymology, which rather suggests one 'exposed to lust' or sex 'indiscriminately offered.'"  
The word prostitute was then carried down through various languages to the present-day Western society. Most sex worker activists groups reject the word prostitute and since the late 1970s have used the term sex worker instead. However, sex worker can also mean anyone who works within the sex industry or whose work is of a sexual nature and is not limited solely to prostitutes.  
A variety of terms are used for those who engage in prostitution, some of which distinguish between different types of prostitution or imply a value judgment about them. Common alternatives for prostitute include escort and whore; however, not all professional escorts are prostitutes.
The English word whore derives from the Old English word hōra, from the Proto-Germanic *hōrōn (prostitute), which derives from the Proto-Indo-European root *keh₂- meaning "desire", a root which has also given us Latin cārus (dear), whence the French cher (dear, expensive) and the Latin cāritās (love, charity). Use of the word whore is widely considered pejorative, especially in its modern slang form of ho. In Germany, however, most prostitutes' organizations deliberately use the word Hure (whore) since they feel that prostitute is a bureaucratic term. Those seeking to remove the social stigma associated with prostitution often promote terminology such as sex worker, commercial sex worker (CSW) or sex trade worker. Another commonly used word for a prostitute is hooker. Although a popular etymology connects "hooker" with Joseph Hooker, a Union general in the American Civil War, the word more likely comes from the concentration of prostitutes around the shipyards and ferry terminal of the Corlear's Hook area of Manhattan in the 1820s, who came to be referred to as "hookers".  A streetwalker solicits customers on the streets or in public places, while a call girl makes appointments by phone, or in recent years, through email or the internet.
Correctly or not, use of the word prostitute without specifying a sex may commonly be assumed to be female; compound terms such as male prostitution or male escort are therefore often used to identify males. Those offering services to female customers are commonly known as gigolos; those offering services to male customers are hustlers or rent boys.
Clients of prostitutes, most often men by prevalence, are sometimes known as johns or tricks in North America and punters in Britain and Ireland. These slang terms are used among both prostitutes and law enforcement for persons who solicit prostitutes.  The term john may have originated from the frequent customer practice of giving one's name as "John", a common name in English-speaking countries, in an effort to maintain anonymity. In some places, men who drive around red-light districts for the purpose of soliciting prostitutes are also known as kerb crawlers.
The word "prostitution" can also be used metaphorically to mean debasing oneself or working towards an unworthy cause or "selling out".  In this sense, "prostituting oneself" or "whoring oneself" the services or acts performed are typically not sexual. For instance, in the book The Catcher in the Rye, Holden Caulfield says of his brother ("D.B."): "Now he's out in Hollywood, D.B., being a prostitute. If there's one thing I hate, it's the movies. Don't even mention them to me." D.B. is not literally a prostitute; Holden feels that his job writing B-movie screenplays is morally debasing.
The prostitution metaphor, "traditionally used to signify political inconstancy, unreliability, fickleness, a lack of firm values and integrity, and venality, has long been a staple of Russian political rhetoric."  One of the famous insults of Leon Trotsky made by Vladimir Lenin was calling him a "political prostitute".  Leon Trotsky used this epithet himself, calling German Social Democracy, at that time "corrupted by Kautskianism", a "political prostitution disguised by theories".  In 1938, he used the same description for the Comintern, saying that the chief aim of the Bonapartist clique of Stalin during the preceding several years "has consisted in proving to the imperialist 'democracies' its wise conservatism and love for order. For the sake of the longed alliance with imperialist democracies [Stalin] has brought the Comintern to the last stages of political prostitution." 
Besides targeting political figures, the term is used in relation to organizations and even small countries, which "have no choice but to sell themselves", because their voice in world affairs is insignificant. In 2007, a Russian caricature depicted the Baltic states as three "ladies of the night", "vying for the attentions of Uncle Sam, since the Russian client has run out of money". 
Usage of the "political prostitute" moniker is by no means unique to Russian political lexicon, such as when a Huffington Post contributor expressed the opinion that Donald Trump was "prostituting himself to feed his ego and gain power" when he ran for President of the United States. 
Sex work researcher and writer Gail Pheterson writes that these metaphorical usages exist because "the term "prostitute" gradually took on a Christian moralist tradition, as being synonymous with debasement of oneself or of others for the purpose of ill-gotten gains". 
Ancient Near East
In the Ancient Near East along the Tigris–Euphrates river system there were many shrines and temples or "houses of heaven" dedicated to various deities documented by the Ancient Greek historian Herodotus in The Histories  where sacred prostitution was a common practice.  It came to an end when the emperor Constantine in the fourth century AD destroyed the goddess temples and replaced them with Christianity. 
As early as the 18th century BC, ancient Mesopotamia recognized the need to protect women's property rights. In the Code of Hammurabi, provisions were found that addressed inheritance rights of women, including female prostitutes. 
Ancient Hebrew culture
According to Zohar and the Alphabet of Ben Sira, there were four angels of sacred prostitution, who mated with archangel Samael. They were the queens of the demons Lilith, Naamah, Agrat Bat Mahlat and Eisheth Zenunim. 
Both women and boys engaged in prostitution in ancient Greece.  Female prostitutes could be independent and sometimes influential women. They were required to wear distinctive dresses and had to pay taxes. Some similarities have been found between the Greek hetaera, the Japanese oiran, and also the Indian tawaif. Some prostitutes in ancient Greece, such as Lais were as famous for their company as their beauty, and some of these women charged extraordinary sums for their services.
Prostitution in ancient Rome was legal, public, and widespread. A registered prostitute was called a meretrix while the unregistered one fell under the broad category prostibulae. There were some commonalities with the Greek system, but as the Empire grew, prostitutes were often foreign slaves, captured, purchased, or raised for that purpose, sometimes by large-scale "prostitute farmers" who took abandoned children. Indeed, abandoned children were almost always raised as prostitutes.  Enslavement into prostitution was sometimes used as a legal punishment against criminal free women. Buyers were allowed to inspect naked men and women for sale in private and there was no stigma attached to the purchase of males by a male aristocrat.
According to Shia Muslims, Muhammad sanctioned fixed-term marriage—muta'a in Iraq and sigheh in Iran—which has instead been used as a legitimizing cover for sex workers, in a culture where prostitution is otherwise forbidden.  Sunni Muslims, who make up the majority of Muslims worldwide, believe the practice of fixed-term marriage was abrogated and ultimately forbidden by either Muhammad, or one of his successors, Umar. Sunnis regard prostitution as sinful and forbidden. Some Western writers have argued that mut'ah approximates prostitution.  and Nikah misyar  Julie Parshall writes that mut'ah is legalised prostitution which has been sanctioned by the Twelver Shia authorities. She quotes the Oxford encyclopedia of modern Islamic world to differentiate between marriage (nikah) and mut'ah, and states that while nikah is for procreation, mut'ah is just for sexual gratification.  According to Zeyno Baran, this kind of temporary marriage provides Shi'ite men with a religiously sanctioned equivalent to prostitution.  According to Elena Andreeva's observation published in 2007, Russian travellers to Iran consider mut'ah to be "legalized profligacy" which is indistinguishable from prostitution.  Religious supporters of mut'ah argue that temporary marriage is different from prostitution for a couple of reasons, including the necessity of iddah in case the couple have sexual intercourse. It means that if a woman marries a man in this way and has sex, she has to wait for a number of months before marrying again and therefore, a woman cannot marry more than 3 or 4 times in a year.      
In the early 17th century, there was widespread male and female prostitution throughout the cities of Kyoto, Edo, and Osaka, Japan. Oiran were courtesans in Japan during the Edo period. The oiran were considered a type of yūjo (遊女) "woman of pleasure" or prostitute. Among the oiran, the tayū (太夫) was considered the highest rank of courtesan available only to the wealthiest and highest ranking men. To entertain their clients, oiran practiced the arts of dance, music, poetry, and calligraphy as well as sexual services, and an educated wit was considered essential for sophisticated conversation. Many became celebrities of their times outside the pleasure districts. Their art and fashions often set trends among wealthy women. The last recorded oiran was in 1761. Although illegal in modern Japan, the definition of prostitution does not extend to a "private agreement" reached between a woman and a man in a brothel. Yoshiwara has a large number of soaplands that began when explicit prostitution in Japan became illegal, where women washed men's bodies. They were originally known as toruko-buro, meaning Turkish bath.
A tawaif was a courtesan who catered to the nobility of the Indian subcontinent, particularly during the era of the Mughal Empire. These courtesans danced, sang, recited poetry and entertained their suitors at mehfils. Like the geisha tradition in Japan, their main purpose was to professionally entertain their guests, and while sex was often incidental, it was not assured contractually. High-class or the most popular tawaifs could often pick and choose between the best of their suitors. They contributed to music, dance, theatre, film, and the Urdu literary tradition. 
Throughout the Middle Ages the definition of a prostitute has been ambiguous, with various secular and canonical organizations defining prostitution in constantly evolving terms. Even though medieval secular authorities created legislation to deal with the phenomenon of prostitution, they rarely attempted to define what a prostitute was because it was deemed unnecessary "to specify exactly who fell into that [specific] category" of a prostitute.  The first known definition of prostitution was found in Marseille's thirteenth-century statutes, which included a chapter entitled De meretricibus ("regarding prostitutes").  The Marseillais designated prostitutes as "public girls" who, day and night, received two or more men in their house, and as a woman who "did business trading [their bodies], within the confine[s] of a brothel."  A fourteenth-century English tract, Fasciculus Morum, states that the term prostitute (termed ' meretrix' in this document), "must be applied only to those women who give themselves to anyone and will refuse none, and that for monetary gain".  In general prostitution was not typically a life-time career choice for women. Women usually alternated their career of prostitution with "petty retailing, and victualing," or only occasionally turning to prostitution in times of great financial need.  Women who became prostitutes often did not have the familial ties or means to protect themselves from the lure of prostitution, and it has been recorded on several occasions that mothers would be charged with prostituting their own daughters in exchange for extra money.  Medieval civilians accepted without question the fact of prostitution, it was necessary part of medieval life.  Prostitutes subverted the sexual tendencies of male youth, just by existing. With the establishment of prostitution men were less likely to collectively rape honest women of marriageable and re-marriageable age.  This is most clearly demonstrated in St. Augustine's claim that "the removal of the institution would bring lust into all aspects of the world."  Meaning that without prostitutes to subvert male tendencies, men would go after innocent women instead, thus the prostitutes were actually doing society a favor.
In urban societies there was an erroneous view that prostitution was flourishing more in rural regions rather than in cities, however it has been proven that prostitution was more rampant in cities and large towns.  Although there were wandering prostitutes in rural areas who worked according to the calendar of fairs, similar to riding a circuit, in which prostitutes stopped by various towns based on what event was going on at the time, most prostitutes remained in cities. Cities tended to draw more prostitutes due to the sheer size of the population and the institutionalization of prostitution in urban areas which made it more rampant in metropolitan regions.  Furthermore, in both urban and rural areas of society, women who did not live under the rule of male authority were more likely to be suspected of prostitution than their oppressed counterparts because of the fear of women who did not fit into a stereotypical category outside of marriage or religious life.  Secular law, like most other aspects of prostitution in the Middle Ages, is difficult to generalize due to the regional variations in attitudes towards prostitution.  The global trend of the thirteenth century was toward the development of positive policy on prostitution as laws exiling prostitutes changed towards sumptuary laws and the confinement of prostitutes to red light districts. 
Sumptuary laws became the regulatory norm for prostitutes and included making courtesans "wear a shoulder-knot of a particular color as a badge of their calling" to be able to easily distinguish the prostitute from a respectable woman in society.  The color that designated them as prostitutes could vary from different earth tones to yellow, as was usually designated as a color of shame in the Hebrew communities.  These laws, however, proved no impediment to wealthier prostitutes because their glamorous appearances were almost indistinguishable from noble women.  In the 14th century, London prostitutes were only tolerated when they wore yellow hoods. 
Although brothels were still present in most cities and urban centers, and could range from private bordelages run by a procuress from her home to public baths and centers established by municipal legislation, the only centers for prostitution legally allowed were the institutionalized and publicly funded brothels.  However this did not prevent illegal brothels from thriving. Furthermore, brothels theoretically banned the patronage of married men and clergy also, but it was sporadically enforced and there is evidence of clergymen present in brawls that were documented in brothels.  Thus the clergy were at least present in brothels at some point or another. Brothels also settled the "obsessive fear of the sharing of women" and solved the issue of "collective security."  The lives of prostitutes in brothels were not cloistered like that of nuns and "only some lived permanently in the streets assigned to them."  Prostitutes were only allowed to practice their trade in the brothel in which they worked.  Brothels were also used to protect prostitutes and their clients through various regulations. For example, the law that "forbid brothel keepers [from] beat[ing] them."  However, brothel regulations also hindered prostitutes' lives by forbidding them from having "lovers other than their customers" or from having a favored customer. 
Courts showed the conflicting views on the role of prostitutes in secular law as prostitutes could not inherit property, defend themselves in court, or make accusations in court.  However, prostitutes were sometimes called upon as witnesses during trial. 
By the end of the 15th century attitudes seemed to have begun to harden against prostitution. An outbreak of syphilis in Naples 1494 which later swept across Europe, and which may have originated from the Columbian Exchange,  and the prevalence of other sexually transmitted diseases from the earlier 13th century, may have been causes of this change in attitude. By the early 16th century the association between prostitutes, plague, and contagion emerged, causing brothels and prostitution to be outlawed by secular authority.  Furthermore, outlawing brothel-keeping and prostitution was also used to "strengthen the criminal law" system of the sixteenth-century secular rulers.  Canon law defined a prostitute as "a promiscuous woman, regardless of financial elements."  The prostitute was considered a "whore … who [was] available for the lust of many men," and was most closely associated with promiscuity. 
The Church's stance on prostitution was three-fold: “acceptance of prostitution as an inevitable social fact, condemnation of those profiting from this commerce, and encouragement for the prostitute to repent."  The Church was forced to recognize its inability to remove prostitution from the worldly society, and in the fourteenth century "began to tolerate prostitution as a lesser evil."  However, prostitutes were to be excluded from the Church as long as they practiced.  Around the twelfth century, the idea of prostitute saints took hold, with Mary Magdalene being one of the most popular saints of the era. The Church used Mary Magdalene's biblical history of being a reformed harlot to encourage prostitutes to repent and mend their ways.  Simultaneously, religious houses were established with the purpose of providing asylum and encouraging the reformation of prostitution. 'Magdalene Homes' were particularly popular and peaked especially in the early fourteenth century.  Over the course of the Middle Ages, popes and religious communities made various attempts to remove prostitution or reform prostitutes, with varying success. 
With the advent of the Protestant Reformation, numbers of Southern German towns closed their brothels in an attempt to eradicate prostitution.  In some periods prostitutes had to distinguish themselves by particular signs, sometimes wearing very short hair or no hair at all, or wearing veils in societies where other women did not wear them. Ancient codes regulated in this case the crime of a prostitute that dissimulated her profession. In some cultures, prostitutes were the sole women allowed to sing in public or act in theatrical performances.
According to Dervish Ismail Agha, in the Dellâkname-i Dilküşâ, the Ottoman archives,   in the Turkish baths, the masseurs were traditionally young men, who helped wash clients by soaping and scrubbing their bodies. They also worked as sex workers.  The Ottoman texts describe who they were, their prices, how many times they could bring their customers to orgasm, and the details of their sexual practices.
During the British East India Company's rule in India in the late 18th and early 19th centuries, it was initially fairly common for British soldiers to engage in inter-ethnic prostitution in India, where they frequently visited local Indian nautch dancers.  As British females began arriving in British India in large numbers from the early to mid-19th century, it became increasingly uncommon for British soldiers to visit Indian prostitutes, and miscegenation was despised altogether after the events of the Indian Rebellion of 1857. 
In the 19th century, legalized prostitution became a public controversy as France and then the United Kingdom passed the Contagious Diseases Acts, legislation mandating pelvic examinations for suspected prostitutes. This legislation applied not only to the United Kingdom and France, but also to their overseas colonies. France, instead of trying to outlaw prostitution began to view prostitution as an evil necessary for society to function. France chose to regulate prostitution, introducing a Morals Brigade onto the streets of Paris.  A similar situation did in fact exist in the Russian Empire; prostitutes operating out of government-sanctioned brothels were given yellow internal passports signifying their status and were subjected to weekly physical exams. A major work, Prostitution, Considered in Its Moral, Social, and Sanitary Aspects, was published by William Acton in 1857, which estimated that the County of London had 80,000 prostitutes and that 1 house in 60 was serving as a brothel.  Leo Tolstoy's novel Resurrection describes legal prostitution in 19th-century Russia.
During this period, prostitution was also very prominent in the Barbary Coast, San Francisco as the population was mainly men, due to the influx from the Gold Rush.  One of the more successful madams was Belle Cora, who inadvertently got involved in a scandal involving her husband, Charles Cora, shooting US Marshal William H. Richardson.  This led to the rise of new statutes against prostitution, gambling and other activities seen as "immoral". 
The leading theorists of Communism opposed prostitution. Communist governments often attempted to repress the practice immediately after obtaining power, although it always persisted. In contemporary Communist countries, it remains illegal but is nonetheless common.  The economic decline brought about by the collapse of the Soviet Union led to increased prostitution in many current or former Communist countries. 
Originally, prostitution was widely legal in the United States. Prostitution was made illegal in almost all states between 1910 and 1915 largely due to the influence of the Woman's Christian Temperance Union. On the other hand, prostitution generated much national revenue in South Korea, hence the military government encouraged prostitution for the U.S. military.  
In 1956, the United Kingdom introduced the Sexual Offences Act 1956. While this law did not criminalise the act of prostitution in the United Kingdom itself, it prohibited such activities as running a brothel. Soliciting was made illegal by the Street Offences Act 1959. These laws were partly repealed, and altered, by the Sexual Offences Act 2003 and the Policing and Crime Act 2009.
Beginning in the late 1980s, many states in the US increased the penalties for prostitution in cases where the prostitute is knowingly HIV-positive. Penalties for felony prostitution vary, with maximum sentences of typically 10 to 15 years in prison.
Since the break up of the Soviet Union, thousands of eastern European women end up as prostitutes in China, Western Europe, Israel, and Turkey every year; some enter the profession willingly, but many are tricked, coerced, or kidnapped, and often experience captivity and violence.  There are tens of thousands of women from eastern Europe and Asia working as prostitutes in Dubai. Men from Saudi Arabia and the United Arab Emirates form a large proportion of the customers. 
Prostitutes' salaries and payments fluctuate according to the economic conditions of their respective countries. Prostitutes who usually have foreign clients, such as business travelers, depend on good foreign economic conditions.  Payment may vary according to regulations made by pimps, brothel keepers, madams, and procurers, who usually take a slice out of a prostitute's income.  Prices may further depend on demand; popular, high-end prostitutes can earn significant amounts of money (upwards of $5,000 per client),  and virgins may receive even higher payments.

Roughly speaking, the possible attitudes are:
- "Prostitution should be tolerated by society":
- decriminalization: "prostitution is labor like any other. Sex industry premises should not be subject to any special regulation or laws", the current situation in New Zealand; the laws against operating a brothel, pimping and street prostitution are struck down, but prostitution is hardly regulated at all. Proponents of this view often cite instances of government regulation under legalization that they consider intrusive, demeaning, or violent, but feel that criminalization adversely affects sex workers.  Amnesty International is one of the notable groups calling for the decriminalization of prostitution.   
- regulation: prostitution may be considered a legitimate business; prostitution and the employment of prostitutes are legal, but regulated; the current situation in the Netherlands, Germany,  most of Australia and parts of Nevada (see Prostitution in Nevada). The degree of regulation varies very much; for example, in the Netherlands, prostitutes are not required to undergo mandatory health checks (see Prostitution in the Netherlands), while in Nevada, the regulations are very strict (see Prostitution in Nevada).
- "Prostitution should not be tolerated":
- abolitionism (prostitution itself is not prohibited, but most associated activities are illegal, in an attempt to make it more difficult to engage in prostitution, prostitution is heavily discouraged and seen as a social problem): prostitution (the exchange of sexual services for money) is legal, but the surrounding activities such as public solicitation, operating a brothel and other forms of pimping are prohibited. This is to some extent the current situation in Great Britain, where prostitution is considered "both a public nuisance and sexual offence", and Italy among others. 
- neo-abolitionism ("prostitution is inherently abusive, both a cause and consequence of inequality,  a form of violence against women, a violation of human rights, the clients of the prostitutes exploit the prostitutes"): prostitutes are not prosecuted, but their clients and pimps are, which is the current situation in Sweden, France, Norway and Iceland (in Norway the law is even more strict, forbidding also having sex with a prostitute abroad). 
- prohibitionism (both prostitutes and clients are criminalized and are seen as immoral, they are considered criminals): the prevailing attitude nearly everywhere in the United States, with a few exceptions in some rural Nevada counties (see Prostitution in Nevada)
In some countries, there is controversy regarding the laws applicable to sex work. For instance, the legal stance of punishing pimping while keeping sex work legal but "underground" and risky is often denounced as hypocritical; opponents suggest either going the full abolition route and criminalize clients or making sex work a regulated business.
Many countries have sex worker advocacy groups which lobby against criminalization and discrimination of prostitutes. These groups generally oppose Nevada-style regulation and oversight, stating that prostitution should be treated like other professions. In the United States of America, one such group is COYOTE (an abbreviation for "Call Off Your Old Tired Ethics") and another is the North American Task Force on Prostitution.  In Australia the lead sex worker rights organisation is Scarlet Alliance.  International prostitutes' rights organizations include the International Committee for Prostitutes' Rights and the Network of Sex Work Projects. 
Other groups, often with religious backgrounds, focus on offering women a way out of the world of prostitution while not taking a position on the legal question.
Prostitution is a significant issue in feminist thought and activism. Many feminists are opposed to prostitution, which they see as a form of exploitation of women and male dominance over women, and as a practice which is the result of the existing patriarchal societal order. These feminists argue that prostitution has a very negative effect, both on the prostitutes themselves and on society as a whole, as it reinforces stereotypical views about women, who are seen as sex objects which can be used and abused by men. Other feminists hold that prostitution can be a valid choice for the women who choose to engage in it; in this view, prostitution must be differentiated from forced prostitution, and feminists should support sex worker activism against abuses by both the sex industry and the legal system.
In February 2014, the members of the European Parliament voted in a non-binding resolution, (adopted by 343 votes to 139; with 105 abstentions), in favor of the 'Swedish Model' of criminalizing the buying, but not the selling of sex. 
The position of prostitution and the law varies widely worldwide, reflecting differing opinions on victimhood and exploitation, inequality, gender roles, gender equality, ethics and morality, freedom of choice, historical social norms, and social costs and benefits.
Legal themes tend to address four types of issue: victimhood (including potential victimhood), ethics and morality, freedom of choice, and general benefit or harm to society (including harm arising indirectly from matters connected to prostitution).
Prostitution may be considered a form of exploitation (e.g., Sweden, Norway, Iceland, where it is illegal to buy sexual services, but not to sell them — the client commits a crime, but not the prostitute), a legitimate occupation (e.g., Netherlands, Germany, where prostitution is regulated as a profession) or a crime (e.g., many Muslim countries, where the prostitutes face severe penalties).
The legal status of prostitution varies from country to country, from being legal and considered a profession to being punishable by death.  Some jurisdictions outlaw the act of prostitution (the exchange of sexual services for money); other countries do not prohibit prostitution itself, but ban the activities typically associated with it (soliciting in a public place, operating a brothel, pimping etc.), making it difficult to engage in prostitution without breaking any law; and in a few countries prostitution is legal and regulated.
In 1949, the UN General Assembly adopted a convention stating that "prostitution and the accompanying evil of the traffic in persons for the purpose of prostitution are incompatible with the dignity and worth of the human person",  requiring all signing parties to punish pimps and brothel owners and operators and to abolish all special treatment or registration of prostitutes. As of January 2009, the convention was ratified by 95 member nations including France, Spain, Italy, Denmark, and not ratified by another 97 member nations including Germany, the Netherlands, the United Kingdom and the United States.

In Las Vegas, prostitution is often promoted overtly on the Las Vegas Strip by third party workers distributing risque flyers with the pictures and phone numbers of escorts (despite the fact that prostitution is illegal in Las Vegas and Clark County, see Prostitution in Nevada).
The way in which prostitutes advertise their presence varies widely. Some remain in apartments which have hints or clues outside such as posters with "model" written on them to lure potential customers inside. Others advertise by putting numbers or location in phoneboxes or in online or newspaper ads. In more sexually permissive societies, prostitutes can advertise in public view, such as through display windows. In sexually restrictive societies it may occur through word-of-mouth and other means. 
A difficulty facing migrant prostitutes in many developed countries is the illegal residence status of some of these women. They face potential deportation, and so do not have recourse to the law. Hence there are brothels that may not adhere to the usual legal standards intended to safeguard public health and the safety of the workers.
The immigration status of the persons who sell sexual services is – particularly in Western Europe – a controversial and highly debated political issue. Currently, in most of these countries most prostitutes are immigrants, mainly from Eastern and Central Europe; in Spain and Italy 90% of prostitutes are estimated to be migrants, in Austria 78%, in Switzerland 75%, in Greece 73%, in Norway 70% (according to a 2009 TAMPEP report, Sex Work in Europe-A mapping of the prostitution scene in 25 European countries).  An article in Le Monde diplomatique in 1997 stated that 80% of prostitutes in Amsterdam were foreigners and 70% had no immigration papers. 
Survival sex is when the prostitute is driven to prostitution by a need for basic necessities such as food or shelter. This type of prostitution is common among the homeless and in refugee camps. The term is used in the sex trade and by aid workers, although some practitioners do not regard the act as exploitative.
Use of children
Regarding the prostitution of children the laws on prostitution as well as those on sex with a child apply. If prostitution in general is legal there is usually a minimum age requirement for legal prostitution that is higher than the general age of consent (see above for some examples). Although some countries do not single out patronage of child prostitution as a separate crime, the same act is punishable as sex with an underage person.
In India, the federal police say that around 1.2 million children are believed to be involved in prostitution.  A CBI statement said that studies and surveys sponsored by the ministry of women and child development estimated that about 40% of all India's prostitutes are children. 
In Bangladesh, child prostitutes are known to take the drug Oradexon, also known as dexamethasone. This over-the-counter steroid, usually used by farmers to fatten cattle, makes child prostitutes look larger and older. Charities say that 90% of prostitutes in the country's legalized brothels use the drug. According to social activists, the steroid can cause diabetes, high blood pressure and is highly addictive.   
Thailand's Health System Research Institute reported that children in prostitution make up 40% of prostitutes in Thailand. 
Some adults travel to other countries to have access to sex with children, which is unavailable in their home country. Cambodia has become a notorious destination for sex with children.   Thailand is also a destination for child sex tourism.   Several western countries have recently enacted laws with extraterritorial reach, punishing citizens who engage in sex with minors in other countries. As the crime usually goes undiscovered, these laws are rarely enforced.   
Among the elderly
Prostitution among the elderly is a phenomenon reported in South Korea where elderly women, called Bacchus Ladies, turn to prostitution out of necessity. They are called that because many also sell the popular Bacchus energy drink to make ends meet. State pensions of about ₩200,000 ( US$168) provide a basic income but are often not enough to cover the rising medical bills of old age. It first arose after the 1997 Asian financial crisis when it became more difficult for children and grandchildren to support their elders. Clients tend to be more senior. The use of erection inducing injections with reused needles has contributed to the spread of sexually transmitted disease.  
In the United States, the homicide rate for female prostitutes was estimated to be 204 per 100,000.  There are substantial differences in rates of victimization between street prostitutes and indoor prostitutes who work as escorts, call girls, or in brothels and massage parlors.   Violence against male prostitutes is less common. 
Prostitution may sometimes be associated with illegal, abusive, and dangerous activities. One view maintains that this results from prostitution being stigmatized or illegal, or both.  Another, however, believes that legalizing and regulating prostitution does not improve the situation, but instead makes it worse, creating a parallel illegal prostitution industry, and failing to dissociate the legal part of the sex trade from crime.    
Sex trafficking is defined as using coercion or force to transport an unwilling person into prostitution or other sexual exploitation.  The United Nations stated in 2009 that sex trafficking is the most commonly identified form of human trafficking and estimates that about 79% of human trafficking reported is for prostitution (although the study notes that this may be the result of statistical bias and that sex trafficking tends to receive the most attention and be the most visible).  Sex trafficking has been described by Kul Gautum, Deputy Executive Director of UNICEF, as "the largest slave trade in history."  It is also the fastest growing criminal industry, predicted to outgrow drug trafficking.    While there may be a higher number of people involved in slavery today than at any time in history, the proportion of the population is probably the smallest in history.  
“Annually, according to U.S. Government-sponsored research completed in 2006, approximately 800,000 people are trafficked across national borders, which does not include millions trafficked within their own countries. Approximately 80 percent of transnational victims are women and girls and up to 50 percent are minors," estimated the US Department of State in a 2008 study, in reference to the number of people estimated to be victims of all forms of human trafficking.  Due in part to the illegal and underground nature of sex trafficking, the actual extent of women and children forced into prostitution is unknown. A statistical analysis of various measures of trafficking found that the legal status of prostitution did not have a significant impact on trafficking. 
Children are sold into the global sex trade every year. Often they are kidnapped or orphaned, and sometimes they are sold by their own families. According to the International Labour Organization, the occurrence is especially common in places such as Thailand, the Philippines, Sri Lanka, Vietnam, Cambodia, Nepal and India. 
Globally, forced labour generates an estimated $31 billion, about half of it in the industrialised world and around one tenth in transitional countries, according to the International Labour Organization in a report on forced labour ("A global alliance against forced labour", ILO, 11 May 2005).  Trafficking in people has been facilitated by factors such as porous borders and advanced communication technologies, and has become increasingly transnational in scope and highly financially lucrative.
The most common destinations for victims of human trafficking are Thailand, Japan, Israel, Belgium, the Netherlands, Germany, Italy, Turkey and the US, according to a report by the UNODC ( UN Office on Drugs and Crime). 
Major sources of trafficked persons include Thailand, China, Nigeria, Albania, Bulgaria, Belarus, Moldova and Ukraine. 
Prostitution, often when it is illegal, is used in extortion and blackmail, which always involves extortion, where the extortionist threatens to reveal information about a victim or their family members that is potentially embarrassing, socially damaging, or incriminating unless a demand for money, property, or services is met. The subject of the extortion may be manipulated into or voluntarily solicit the use of prostitution which is then later used to extort money or for profit otherwise. The film The Godfather Part II famously depicts the role of Senator Geary who is implicated in the use of prostitution in order to gain his compliance on political issues.
In street prostitution, the prostitute solicits customers while waiting at street corners, sometimes called "the track" by pimps and prostitutes alike. They usually dress in skimpy, provocative clothing, regardless of the weather. Street prostitutes are often called "streetwalkers" while their customers are referred to as "tricks" or "johns." Servicing the customers is described as "turning tricks." The sex is usually performed in the customer's car, in a nearby alley, or in a rented room. Motels and hotels that accommodate prostitutes commonly rent rooms by the half or full hour.
In Russia and other countries of the former USSR, prostitution takes the form of an open-air market. One prostitute stands by a roadside, and directs cars to a so-called "tochka" (usually located in alleyways or carparks), where lines of women are paraded for customers in front of their car headlights. The client selects a prostitute, whom he takes away in his car. Prevalent in the late 1990s, this type of service has been steadily declining in recent years.
A "lot lizard" is a commonly encountered special case of street prostitution.  Lot lizards mainly serve those in the trucking industry at truck stops and stopping centers. Prostitutes will often proposition truckers using a CB radio from a vehicle parked in the non-commercial section of a truck stop parking lot, communicating through codes based on commercial driving slang, then join the driver in his truck.
Window prostitution is a form of prostitution that is fairly common in the Netherlands and surrounding countries.  The prostitute rents a window plus workspace off a window operator for a certain period of time, often per day or part of a day.    The prostitute is also independent and recruits her own customers and also negotiates the price and the services to be provided.   
Brothels are establishments specifically dedicated to prostitution, often confined to special red-light districts in big cities. Other names for brothels include bordello, whorehouse, cathouse, knocking shop, and general houses. Prostitution also occurs in some massage parlours, and in Asian countries in some barber shops where sexual services may be offered as a secondary function of the premises.
Escort services may be distinguished from prostitution or other forms of prostitution in that sexual activities are often not explicitly advertised as necessarily included in these services; rather, payment is often noted as being for an escort's time and companionship only, although there is often an implicit assumption that sexual activities are expected.
In escort prostitution, the act takes place at the customer's residence or hotel room (referred to as out-call), or at the escort's residence or in a hotel room rented for the occasion by the escort (called in-call). The prostitute may be independent or working under the auspices of an escort agency. Services may be advertised over the Internet, in regional publications, or in local telephone listings.
Use of the Internet by prostitutes and customers is common.  A prostitute may use adult boards or create a website of their own with contact details, such as email addresses. Adult contact sites, chats and on-line communities are also used. This, in turn, has brought increased scrutiny from law enforcement, public officials, and activist groups toward online prostitution. In 2009, Craigslist came under fire for its role in facilitating online prostitution, and was sued by some 40 US state attorneys general, local prosecutors, and law enforcement officials.
Reviews of the services of individual prostitutes can often be found at various escort review boards worldwide. These online forums are used to trade information between potential clients, and also by prostitutes to advertise the various services available. Sex workers, in turn, often use online forums of their own to exchange information on clients, particularly to warn others about dangerous clients.
Sex tourism is travel for sexual intercourse with prostitutes or to engage in other sexual activity. The World Tourism Organization, a specialized agency of the United Nations defines sex tourism as "trips organized from within the tourism sector, or from outside this sector but using its structures and networks, with the primary purpose of effecting a commercial sexual relationship by the tourist with residents at the destination". 
As opposed to regular sex tourism, which is often legal, a tourist who has sex with a child prostitute will usually be committing a crime in the host country, under the laws of his own country (notwithstanding him being outside of it) and against international law. Child sex tourism (CST) is defined as a travel to a foreign country for the purpose of engaging in commercially facilitated child sexual abuse.  Thailand, Cambodia, India, Brazil, and Mexico have been identified as leading hotspots of child sexual exploitation. 
Virtual sex, that is, sexual acts conveyed by messages rather than physically, is also the subject of commercial transactions. Commercial phone sex services have been available for decades. The advent of the Internet has made other forms of virtual sex available for money, including computer-mediated cybersex, in which sexual services are provided in text form by way of chat rooms or instant messaging, or audiovisually through a webcam (see camgirl).
According to the paper "Estimating the prevalence and career longevity of prostitute women",  the number of full-time equivalent prostitutes in a typical area in the United States (Colorado Springs, CO, during 1970–1988) is estimated at 23 per 100,000 population (0.023%), of which some 4% were under 18. The length of these prostitutes' working careers was estimated at a mean of 5 years. According to a 2012 report by Fondation Scelles there are between 40 and 42 million prostitutes in the world. 
The number of men who have used a prostitute at least once varies widely from country to country, from an estimated low of between 7%  and 8.8%  in the United Kingdom, to a high of between 59% and 80% in Cambodia.  A study conducted by ProCon – a nonpartisan nonprofit organization – estimated the percentage of men who had paid for sex at least once in their lives, and found the highest rates in Cambodia (between 59 and 80% of men had paid for sex at least once) and Thailand (an estimated 75%), followed by Italy (16.7–45%), Spain (27–39%), Japan (37%), the Netherlands (13.5–21.6%), the United States (15.0–20.0%), and China (6.4-20%).  Nations with higher rates of prostitution clients, or “johns”, display much more positive attitudes towards commercial sex.  In some countries, such as Cambodia and Thailand, sex with prostitutes is considered commonplace and men who do not engage in commercial sex may be considered unusual by their peers.  In Thailand, it has been reported that about 75% of men have visited a prostitute at least once in their lifetimes. In Cambodia, that figure is 59% to 80%. 
In the United States, a 2004 TNS poll reported 15% of all men admitted to having paid for sex at least once in their life.  However, a paper entitled "Prostitution and the sex discrepancy in reported number of sexual partners" concluded that men's self-reporting of prostitutes as sexual partners provides a serious underestimate. 
In Australia, a survey conducted in the early 2000s showed that 15.6% of men aged 16–59 reported paying for sex at least once in their life, and 1.9% had done so in the past year. 
Reports disagree on whether prostitution levels are growing or declining in developed countries. Some studies indicate that the percentage of men engaging in commercial sex in the United States has declined significantly in recent decades: in 1964, an estimated 69–80% of men had paid for sex at least once.  Some have suggested that prostitution levels have fallen in sexually liberal countries, most likely because of the increased availability of non-commercial, non-marital sex  or, for example in Sweden, because of stricter legal penalties.  Other reports suggest a growth in prostitution levels, for example in the US,  where again, sexual liberalisation is suggested as the cause. As Norma Ramos, Executive Director of the Coalition Against Trafficking in Women says "The more the commercial sex industry normalizes this behavior, the more of this behavior you get". 
Prostitutes have long plied their trades to the military in many cultures. For example, the British naval port of Portsmouth had a flourishing local sex industry in the 19th century, and until the early 1990s there were large red-light districts near American military bases in the Philippines. The notorious Patpong entertainment district in Bangkok, Thailand, started as an R&R location for US troops serving in the Vietnam War in the early 1970s. Washington D.C. itself had Murder Bay which attracted the military of the Civil War. The village of Vadia, India is known locally as the village of prostitutes, where unmarried women are involved in prostitution. Mass weddings for children of prostitutes in the village are held to protect them from being pushed into prostitution. 
In some places, prostitution may be associated with the spread of sexually transmitted diseases (STDs). Lack of condom use among prostitutes and their clients has been cited as a factor in the spread of HIV in Asia: "One of the main reasons for the rapid spread of HIV in Asian countries is the massive transmission among sex workers and clients".  As a result, prevention campaigns aimed at increasing condom use by sex workers have been attributed to play a major role in restricting the spread of HIV. 
One of the sources for the spread of HIV in Africa is prostitution, with one study finding that encounters with prostitutes produced 84% of new HIV infections in adult males in Accra, Ghana.  The spread of HIV from urban settings to rural areas in Africa has been attributed to the mobility of farmers who visit sex workers in cities, for example in Ethiopia.  Some studies of prostitution in urban settings in developing countries, such as Kenya, have stated that prostitution acts as a reservoir of STDs within the general population. 
Typical responses to the problem are:
- banning prostitution completely
- introducing a system of registration for prostitutes that mandates health checks and other public health measures
- educating prostitutes and their clients to encourage the use of barrier contraception and greater interaction with health care
Some think that the first two measures are counter-productive. Banning prostitution tends to drive it underground, making safe sex promotion, treatment and monitoring more difficult. Registering prostitutes makes the state complicit in prostitution and does not address the health risks of unregistered prostitutes. Both of the last two measures can be viewed as harm reduction policies.
In countries and areas where safer sex precautions are either unavailable or not practiced for cultural reasons, prostitution is an active disease vector for all STDs, including HIV/AIDS, but the encouragement of safer sex practices, combined with regular testing for sexually transmitted diseases, has been very successful when applied consistently. As an example, Thailand's condom program has been largely responsible for the country's progress against the HIV epidemic.  It has been estimated that successful implementation of safe sex practices in India "would drive the [HIV] epidemic to extinction" while similar measures could achieve a 50% reduction in Botswana.  In 2009, UN Secretary-General Ban Ki-moon urged all countries to remove bans on prostitution and homosexual sex, because "such laws constitute major barriers to reaching key populations with HIV services". In 2012, the Global Commission on HIV and the Law, which was convened by Ban Ki-moon, and which is an independent body, established at the request of the UNAIDS, and supported by a Secretariat based at the UNDP,  reached the same conclusions, also recommending decriminalization of brothels and procuring.     Nevertheless, the report states that:"The content, analysis, opinions and policy recommendations contained in this publication do not necessarily reflect the views of the United Nations Development Programme."
