Remapping Debate has created an interactive map that allows you to visualize the diversity or segregation of a city down to the block. The images attached to this post visualize the “% Black (non-Hispanic)” in each Census area. Data is from 2005-2009.
What I find fascinating about the map on a city-wide level is the way geography and segregation in Seattle go together. The areas with good views on the tops of hills or next to water appear less likely to have large black populations.
On a more neighborhood level, the difference between Capitol Hill and the CD is pretty clear on the map. Madison is a fairly firm divider between the two. The CD appears to be the north end of a path of diversity leading south through Rainier Valley.
The map shows that the neighborhood is diverse, but a lot has changed since the Civil Rights Movement of the 1960s. The following map, from the UW website, shows the segregation of the city’s black population in the Central District in 1960:
