William writes in and introduces himself to his new neighbors.

I’m a data and GIS analyst (and former reporter) who just moved to the Medlock area after working for The Palm Beach Post down in South Florida for the past decade. I specialized in stuff like census and real estate data, so I thought I’d throw together some maps of my new home after seeing your post a couple of weeks ago about the NYT’s census map.

You may be wondering about the map above.  It’s straight off a new post on William’s blog showing the black Atlanta population from the 2010 census.  The darker the shading, the larger % of the group; the higher the bar, the more people from the group in the block.  Pretty interesting way to look at it.  Check out his post for similar maps showing the Atlanta Hispanic and Asian populations.

And for the more hyper-local among us, William also created an interactive, block-by-block Google Map of 2010 Census data for just DeKalb County.  Here’s a screen-shot of it, centered around Decatur.  If you want to play around with it, you’ll have to jump over to William’s blog and scroll down a bit.
