There is nothing subtle about the the county's reputation for racism and segregation. Cowlitz County earns the dubious distinction of having recorded the highest percentage of restricted properties among all the counties of Washington. With more than 8,000 identified so far, it ranks second in number to King County whose population and housing stock is 20 times that of Cowlitz. Many of the restrictions were imposed by the owners of the Long-Bell lumber company which planned and developed the city of Longview starting in 1923, wrapping most of its subdivisions with restrictive covenants banning "any person who is not of the white race." It is only in recent decades that the county has begun to diversify.

Move through the decades from 1980-2020. Select a race category, either by number of residents or percentage. Click a census tract for detailed information about a neighborhood. These maps are hosted by Tableau Public and may take a few seconds to respond. If slow, refresh the page.

 

Notes: Data are from the National Historic Geographic Information System (IPUMS). The most recent data is labeled 2020* but to improve accuracy we use an average of five Census Bureau American Community Survey (ACS) samples from 2018-2022.

Race categories and census tracts: The Census Bureau adds and adjusts the boundaries of census tracts nearly every decade. It also changes the data it reports and the racial categories. For 1940, all nonwhites were reported as a combined category. In 1950, this became two categories, “Negroes” and “Other races.” Since most of the “others” would have been Japanese, Chinese, and Filipinos with small numbers of Native Americans, we relabeled this as “Asian/other races.” It was not until 1970 that a reliable set of questions identified people of Hispanic heritage. That is also when Indigenous Americans were first identified in census tract data.
