Puerto Rico's municipios are county-equivalents in a territory. The Census Bureau estimates them in the same file, so they are shown beneath the ranking with their figures and not ranked among the counties of the states.

Within each state

What this data cannot show

  • These are July 1 estimates from the Census Bureau's Vintage 2025, not counts. A later vintage re-estimates every year and can move a county up or down.
  • Connecticut's counties are its nine planning regions, which the Bureau adopted as county-equivalents in 2022. Other county-equivalents, parishes, boroughs and independent cities, are ranked as counties.
