Oregon Population Estimates and Reports

This report provides population estimates for Oregon and its counties and cities for the years 1980 through 1989. As mandated by Oregon law, the Center for Population Research and Census at Portland State University, acting on behalf of the State Board of Higher Education, annually estimates the July 1 population for each incorporated city and county in Oregon. These figures must be certified to the Secretary of State by December 15. When certified the population estimates are used in the allocation of certain state tax revenues to cities and counties.
