Missouri was the nation’s 18th-largest state in 2025, with a population of 6.27 million. From 2024 to 2025 the state gained more than 27,000 residents, an annual growth rate of 0.4%.
Population change reflects natural change (births minus deaths) and migration. From 2020 to 2025 Missouri’s population rose by about 115,000, or 1.9%. During that period the state experienced a natural decrease—deaths outnumbered births by more than 12,000—but that loss was more than offset by migration: roughly 70,000 international migrants and 57,000 domestic migrants moved to Missouri.
