2024 Population estimates for the U.S. and States
Dec 19, 2024
DEC. 19, 2024 — The U.S. population grew by nearly 1.0% between 2023 and 2024, according to the new Vintage 2024 population estimates released today by the U.S. Census Bureau.
As the nation’s population surpasses 340 million, this is the fastest annual population growth the nation has seen since 2001 — a notable increase from the record low growth rate of 0.2% in 2021. The growth was primarily driven by rising net international migration.
Net international migration, which refers to any change of residence across U.S. borders (the 50 states and the District of Columbia), was the critical demographic component of change driving growth in the resident population. With a net increase of 2.8 million people, it accounted for 84% of the nation’s 3.3 million increase in population between 2023 and 2024. This reflects a continued trend of rising international migration, with a net increase of 1.7 million in 2022 and 2.3 million in 2023.
Iowa's population continues to show growth since 2020, up 1.6% to 3,241,488. Natural change (births minus deaths) was an increase of 10,095 while international migration into Iowa continues to increase as well. Data looking at the state rankings and components of change can be found on the State Data Center's website.
