Population of Oklahoma

Analysis# Oklahoma Population Analysis Oklahoma's population of 4,075,759 in 2024 reflects modest growth of 8.65% over the past decade, positioning the state 28th nationally—a ranking consistent with its mid-tier status among U.S. states. The state's growth trajectory has substantially declined from its peak in the 1910s, when Oklahoma experienced rapid expansion following statehood and oil discovery, contrasting sharply with the single-digit percentage gains of recent years. This deceleration suggests Oklahoma faces demographic challenges common to rural-heavy states, including outmigration to urban centers and aging populations that limit natural increase.
