Our Population Center began in 1956, initiated by the State of Oregon with the purpose of preparing 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. 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.
