Delaware statistical areas
From Wikipedia, the free encyclopedia
The U.S. State of Delaware currently has four statistical areas that have been delineated by the Office of Management and Budget (OMB). On July 21, 2023, the OMB delineated one combined statistical area, two metropolitan statistical areas, and one micropolitan statistical area in Delaware.[1] As of 2023, the largest statistical area in the state is the Philadelphia-Reading-Camden, PA-NJ-DE-MD Combined Statistical Area, which includes Delaware's largest city, Wilmington.
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.
Statistical areas
The OMB defines a core-based statistical area (commonly referred to as a CBSA) as the county or counties (or county-equivalents) surrounding at least one densely-settled core of at least 10,000 population,[2] "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 based on population into metropolitan statistical areas (MSAs) for those with at least 50,000 and micropolitan statistical areas (μSAs) for those with 10,000 to 49,999 people.[2]
The OMB defines a combined statistical area (CSA) as two or more adjacent core-based statistical areas where the employment interchange rate (% commuting from A to B plus % commuting from B to A) is 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.

Notes
- An out-of-state area and its population are displayed in green. An area that extends into more than one state is displayed in purple. A purple population number over a black population number show the total population versus the in-state population. The state's abbreviation is also shown next to the in-state total.
- For CBSAs comprising populations from multiple states, they are listed twice to show both their intrastate population within that CBSA as well as the CBSA's total population. Only the intrastate population is ranked.
- For CSAs comprising populations from multiple states, they are listed twice to show both their intrastate population within that CSA as well as the CSA's total population. Only the intrastate population is ranked.
