The following article lists the
cities and
metropolitan areas with the greatest scientific output, according to the
Nature Index. The Nature Index attempts to objectively measure the scientific output of institutions, cities and countries by the amount of
scientific articles and
papers published in leading journals. Differences in quality are taken into account. Only articles published in 82[note 1] selected quality journals are counted. All these journals are in the English language. They were selected by a committee. If authors from several institutions from different cities are involved in a scientific article, it is divided accordingly, assuming that all researchers were equally involved in the article.
In 2019,
Beijing was the city in the world with the largest scientific output, accounting for 2.8% of the world's total.[2]New York City was second in the world, with about 2% of the world's total. Overall, the United States has the most cities in the top 100 list, followed by China.
