Analysis# Idaho Population Analysis
Idaho's population reached 1,996,364 in 2024, representing 27.35% growth over the past decade—a rate significantly outpacing the national average of roughly 7%. Ranked #37 among U.S. states, Idaho's current growth trajectory contrasts sharply with its peak decade in the 1910s, when the state experienced its highest percentage growth rate, though absolute numbers were substantially smaller. The state's accelerating modern growth reflects migration patterns and economic development that differ markedly from its early 20th-century expansion driven by mining and agricultural settlement.
