Louisiana statistical areas
An enlargeable map of the 19
core-based statistical areas in
Louisiana .
[1]
The
U.S.
State of Louisiana currently has 25
statistical areas that have been delineated by the
Office of Management and Budget (OMB). On July 21, 2023, the OMB delineated six
combined statistical areas , ten
metropolitan statistical areas , and nine
micropolitan statistical areas in Louisiana.
[1]
Statistical areas
The
Office of Management and Budget (OMB) has designated more than 1,000
statistical areas for the
United States and
Puerto Rico .
[2] These statistical areas are important geographic delineations of population clusters used by the OMB, the
United States Census Bureau , planning organizations, and federal, state, and local government entities.
The OMB defines a
core-based statistical area (commonly referred to as a
CBSA ) as "a statistical geographic entity consisting of the
county or counties (or
county-equivalents ) associated with at least one core
[a] of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core."
[2] The OMB further divides core-based statistical areas into
metropolitan statistical areas (MSAs) that have "a population of at least 50,000" and
micropolitan statistical areas (μSAs) that have "a population of at least 10,000, but less than 50,000."
[2]
The OMB defines a
combined statistical area (CSA) as "a geographic entity consisting of two or more adjacent
core-based statistical areas with employment interchange measures
[b] of at least 15%."
[2] The
primary statistical areas (PSAs) include all
combined statistical areas and any
core-based statistical area that is not a constituent of a combined statistical area.
