Population -- Oregon -- Portland Metropolitan Area, United States -- Census 2020, Demography -- Oregon -- Portland Metropolitan Area


Every United States census has challenges ensuring that every person responds and is counted. Individuals who are missed in the census count or “undercounted” for various reasons are often referred to as “hard-to-count” populations. Hard-to-count populations include rural residents, people of color, immigrants, people experiencing homelessness, children under age five, renters, and more.

For the 2010 census, the final mail return rate in Oregon was 76 percent. Census tracts with a mail return response rate of 76 percent or less are highlighted on the map on this page. Response rates closest to the state’s final response rate are light yellow, and those with lower response rates are shown in darker shades of orange and red. Over the next few pages, this article will identify the populations that are potentially being undercounted in these selected census tracts throughout the state.
