A central planning region holds the area’s core, an urban area of at least 50,000 people. This area has no outlying planning regions: no neighboring planning region sends enough commuters to join it. A planning region belongs to one metro or micro area at most, and it counts whole, countryside included.

Principal cities, largest first

  1. Waterbury114,869 people
  2. Shelton41,889 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.
