About PRC

Our website includes information about the Oregon Population Estimates Program, the Oregon State Data Center, and various population research projects.  Our goal is to provide ready access to census and other information on the population of Oregon and to provide timely analyses of the patterns of past, current, and projected future populations in Oregon and of the implications of such patterns for key issues facing Oregon.

The PRC  began in 1956, established by the State of Oregon with the responsibility of preparing the Oregon annual certified population estimates for cities and counties in order to distribute state tax revenues. The original program was transferred in 1965 to Portland State University, where it has taken on additional duties including the Oregon State Data Center, the agency in the state  responsible for disemminating information from the U.S. Census Bureau.

Our programs provide current and historical census and related data for the State of Oregon, and for cities, counties, and other geographic areas in Oregon. The data available also include current population estimates for all counties and places in Oregon and projections of the population of the State and its counties by age and sex. Population estimates are released annually by December 15th; an annual publication entitled the Oregon Population Report is released the following March. Also available are reports describing recent population patterns in the State and their implications for socioeconomic and service change in Oregon. All materials are available on a cost-reimbursable basis.
