Welcome from the Director

Welcome to the website for the Population Research Center, including the Oregon State Data Center, the Oregon Population Estimates Program, and various population research projects. These are an integrated set of activities located in the Nohad A. Toulan School of Urban Studies and Planning, College of Urban and Public Affairs, Portland State University, Portland, Oregon. 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 Population Research Center began in 1956, initiated by the State of Oregon with the purpose to prepare annual 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 lead agency in the state for relationships with 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.
