Connecticut cities by population: sort and filter 30 cities.
Connecticut cities by population lists all 30 included cities in one sortable table (U.S. Census Bureau Vintage 2025). Bridgeport leads at 152,273 residents, followed by Stamford at 139,535. Growth figures compare the April 2020 census base with the July 2025 estimate within one vintage.
Connecticut cities ranked by Census Vintage 2025 estimates.
Connecticut ranking uses Census Vintage 2025 Population Estimates Program data as of July 1, 2025. Ranks are state-scoped, using standard competition ranking ("1224"): tied cities share the lower rank and the next rank is skipped. Growth shown is 2020 base → 2025 — within-vintage; no 2010→2025 figures appear here per methodology §6.
This page covers every city for which Census publishes annual PEP estimates in Connecticut: standard incorporated places, any consolidated city-county governments, and (where applicable) DC or Urban Honolulu. Census-designated places (CDPs) are excluded with one named exception — Urban Honolulu. In states like Rhode Island, Connecticut, and Massachusetts, many residents live in towns and townships rather than incorporated cities; PEP does not publish annual estimates for those places (a V1 limitation), so the city counts for MCD-heavy states may be lower than expected.
