Analysis# Iowa Population Analysis
Iowa's population of 3.22 million in 2024 reflects modest growth, with a 5.76% increase over the past decade placing the state 32nd nationally. The state's growth trajectory peaked in the 1920s before moderating substantially; the 5.76% ten-year rate contrasts sharply with historical volatility documented across the 124-year span from 1900 to 2024. This middling contemporary growth rate suggests Iowa has experienced demographic stagnation relative to faster-growing Sun Belt and Western states, indicating limited in-migration and likely net outflow to higher-growth regions.
