Race and Ethnicity: State of Oregon, Population by Race, White
Beginning in 1980, the Census Bureau began to ask "Spanish/Hispanic origin" as a separate question from the race question; thus, people were allowed to identify themselves as white and Hispanic or black and Hispanic, for example.
In 2000 and 2010, the census questionnaire allowed people to self-identify as one or more races, and added the word "Latino" to the separate question about Hispanic ethnicity. Results from these censuses are tabulated to show the population who identified as one race alone, or that race in combination with another race or with Hispanic/Latino ethnicity.
The base of each bar in this chart shows the number of people who identified as white alone, and not Hispanic/Latino, representing 78.5 percent of the state's residents in the 2010 Census. Since 2000, we've seen a growing number of Oregonians identifying as not only white, but also other races. By 2010, over 330 thousand people identified as white and some other race, or white and Hispanic/Latino.
The Census Bureau produced a helpful Overview of Race and Hispanic Origin to explain how the data were collected and reported in the 2010 Census. A graphical representation of Measuring Race and Ethnicity Across the Decades is also available.
