Population estimates are prepared as of July 1st of each year.
Preliminary estimates are released around November 15th each year. We send a letter to state and local jurisdictions and post them here.
Certified estimates are posted on December 15th.
Supplemental reports are published quarterly, and are posted here two weeks after the end of each quarter. These reflect changes in population due to annexations and other revisions.
Please direct all questions and/or comments regarding the Population Estimates Program to popest@pdx.edu.

With each new release of the annual estimates, the entire time series is revised for all years back to the beginning of the decade (for the state, all counties, and all cities) to reflect the increased data availability, specifically for the COVID-19 period. These revisions increase the accuracy of net changes since the census benchmark (2020 Census). When comparing the 2024 certified estimate to any previous year, you need to use the revised population estimates, not the certified population estimate published last year.
When we revise the estimates for previous years, we keep the certified estimates tables for those previous years as they are. Please do not link the revised estimates for previous years to the annual certified estimates published annually for the last years.
