Methodology · Maine population ranking

Maine cities ranked by Census Vintage 2025 estimates.

Maine 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 Maine: 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.
