Within-vintage change only.
The primary ranking compares July 1, 2024 with July 1, 2025. The table also includes 2020-base-to-2025 change as a secondary sort. Every value comes from Census Vintage 2025. We do not compute 2010 → 2025 because that would cross a methodology seam.
Showing all 734 eligible declining cities out of 19,483 city/place records. Rank 1 is the largest decline. Higher rank numbers indicate smaller declines. The five-year column stays within the same Vintage 2025 series.
Methodology · how this list is built
Three things to know about this data.
The 20,000-resident floor. Cities with fewer than 20,000 residents in the 2024 estimate are excluded. A village declining from 60 to 55 people would otherwise rank near the top on percentage terms; the floor keeps the leaderboard meaningful.
Estimation uncertainty. The Census Population Estimates Program produces annual estimates, not a full enumeration. Single-year changes of a few hundred people may not be statistically meaningful, so the five-year column is provided as context.
Incorporated places only. The Vintage 2025 estimates program does not produce annual estimates for Census-Designated Places (CDPs). This list covers incorporated places, consolidated cities, and the District of Columbia — CDPs are an explicit V2 gap in the dataset.
