Puerto Rico statistical areas

The Commonwealth of Puerto Rico currently has 13 statistical areas that have been delineated by the United States Office of Management and Budget (OMB). On July 21, 2023, the OMB delineated three combined statistical areas, six metropolitan statistical areas, and four micropolitan statistical areas in Puerto Rico.[1][2] As of 2025, the largest of these is the San Juan-Bayamón, PR CSA, comprising the area around the municipality of San Juan, the capital and largest city of Puerto Rico.

Statistical areas

The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas for the United States and Puerto Rico.[3] 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 (CBSA) as the county or counties (or county-equivalents) surrounding at least one densely-settled core of at least 10,000 population,[3] "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".[3] The OMB further divides a CBSA based on population into a metropolitan statistical area (MSA) for those with at least 50,000 people or a micropolitan statistical area (μSA) for those with 10,000 to 49,999 people.[3]

The OMB defines a combined statistical area (CSA) as two or more adjacent CBSAs where the employment interchange rate (percent commuting from A to B plus percent commuting from B to A) is at least 15%.[3] A primary statistical area (PSA) includes all CSAs and any CBSA that is not a constituent of a combined statistical area.
