About this ranking
- Source
- U.S. Census Bureau — County Resident Population Estimates (CO-EST2025-ALLDATA), Vintage 2025
- Reference interval

- Ranked by
- Percentage change, largest increase first
- Formula
- Change = 2025 estimate − 2020 estimate; percentage = change ÷ 2020 estimate × 100
- Ties
- Counties with equal percentage change share a rank; their display order is settled by name and then by official Census geographic identifier, so the order is the same everywhere.
A percentage change can look large when the starting population is small, which is why every row shows both endpoint estimates and the numeric change beside it. These estimates record how a county's population changed, not why it changed.
