The Population Research Center service to the State of Oregon began in 1956 with the creation of the Oregon Population Estimates Program, which chartered PRC with preparing annual population estimates for Oregon cities and counties. The Center moved to Portland State University in 1965, and now includes the Oregon State Data Center. This appointment added the responsibility of acting as lead state agency in working with the U.S. Census Bureau to disseminate information at local levels. Additionally, PRC is designated as the lead state representative in partnering with the Census Bureau through the Federal-State Cooperative for Population Estimates (FSCPE), and as participants in the Federal-State Cooperative for Population Projections.
