Population projections are made for July 1 of each year in the projection period. In addition to the medium series that we deem as the most likely scenario, we also produced a low series and a high series. Please refer to the Projections Methodology section near the bottom of the page for assumptions and input data used for these alternative series.
Sub-county population projections are made for July 1 of each year. These are consistent with the 2022 medium series of county population projections. Please refer to the Projections Methodology section near the bottom of the page for details on the sub-county projections process.
