We’ve featured other data visualization maps on Baltimore Fishbowl, and even other data visualization maps that depict segregation. But none have been quite so, well, beautiful as the racial dot map put together by demographer Dustin Cable.

In Cable’s map, each point represents an individual person. Yes, that means that there’s a tiny dot somewhere on this map that stands for you. Of course, the overall picture is more like a impressionist painting, fuzzy around the edges and distinct only when you look up close. Zooming in allows an increasingly precise look at where people live in and around the city:  from a distance, Baltimore clearly reveals itself as a majority-black city, with majority-white outposts extending to the north. But a closer look complicates things:

For reference:  1 green dot = 1 black person; 1 blue dot = 1 white person; 1 red dot = 1 Asian person; 1 yellow dot = 1 Hispanic person; and 1 brown dot = 1 “other” person.

Notice how the area’s suburban black population clusters along Liberty Road, while the northern Charles Street corridor is much more heavily white.

Zooming in even closer, you start to be able to see the city’s burgeoning Hispanic population in the Highlandtown area.

That big white spot is the Johns Hopkins Homewood campus, and all those red dots indicate the university’s concentration of Asian students, many of whom live right near campus. Again, a clear geographic demarcation seems to exist — this time, it’s Greenmount Avenue that serves as the de facto racial boundary.
