A central county holds the area’s core, an urban area of 10,000 to 49,999 people. This area has no outlying counties: no neighboring county sends enough commuters to join it. A county belongs to one metro or micro area at most, and it counts whole, countryside included.
Principal city
- Pierre13,948 people
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). People counts are American Community Survey 2020–2024 5-year estimates.
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.
