A central parish holds the area’s core, an urban area of at least 50,000 people. An outlying parish is in the area because of commuting: at least a quarter of its workers have jobs in the central parish, or at least a quarter of the people working there live in them. A parish belongs to one metro or micro area at most, and it counts whole, countryside included.

OMB names the area after its largest principal cities. A principal city is the area’s largest city, plus any other city that is very large or a big job center, and smaller ones with at least as many jobs as working residents (2020 Census and commuting figures).

Before using this answer on a form
A metro or micro area is a statistical area that OMB draws for federal statistics. It is not a city, a local government or a mailing address, and it is not a measure of urban and rural: whole counties count, rural parts included. Programs that use metro areas, such as housing income limits or wage rates, can use their own version of these lists; check the program’s own list for an address.
