Projections of population with components of change, births, and public school enrollment at the state and county level produced by the Demographic Research Unit (DRU).
Interim Projections Series
This interim series reflects the July 1, 2022, state and county population estimates published in December 2022 and is informed by the U.S. Census Bureau’s blended base – a combination of Census 2020 PL94, 2020 Demographic Analysis, and the Bureau’s Vintage 2020 estimates.
DRU plans to release a full projection series based on Census 2020 data in Summer 2024 once the final 2020 Census data is released.
