Race and ethnicity 1990: San Francisco, Oakland, Berkeley
Racial and ethnic divisions in US cities, inspired by Bill Rankin's map of Chicago, looking back to 1990.
Red is White, Blue is Black, Green is Asian, Orange is Hispanic, Yellow is Other, and each dot is 25 residents.

And no, I haven't downloaded or processed the data for the whole country for 1990 (yet). It's also not really directly comparable to the 2000 or 2010 maps I posted since those are by block and the 1990 data is only available to the blockgroup (group of 10 blocks) level, so the dots here are further from people's actual residences.
Still interesting to see how things have changed. San Francisco and Oakland both had much larger black populations than they do now (or did in 2000).
