Current Estimates
State, County, Place Level Population Estimates. Because a decennial census was conducted in 2020, the July 1, 2020 population estimates are provisional. When the Census 2020 results are published in the next few months, the Office of Economic Opportunity will revise these provisional estimates and produce final population estimates for July 1, 2020.
