    Methodology · Delaware population ranking

    Delaware cities ranked by Census Vintage 2025 estimates.

    Delaware 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 ranking includes incorporated places and consolidated governments in our city dataset, with Washington, D.C. and Urban Honolulu as named special cases. Census-designated places and county subdivisions are separate geographies.
