Here’s a map of where people in Fulton County live, color-coded by race.
The map is kind of slow b/c it’s really big.
This is a “dot density” map by U.S. Census block — a block includes a couple of streets in most cases. It’s not a dot on every person’s house. There’s a dot for every 50 people. The dot is randomly placed somewhere in their block. That’s why some dots show up in parks — it’s not that all those people live in the park. It’s that a park is part of a block and some dots for that block got stuck on the parks.
“Latino” and “Multiracial” are not on here, but may be indicated in “Other.” I’m going by the U.S. Census 2010 table P3, Race. I’m basically using the categories they used. But because there were vanishingly few native Alaskans, native Hawaiians and Pacific Islanders, I merged them with other folks in the Census’ “Other” category. According to the Census (page B-9), “Other” is anything anybody put that doesn’t fit in the other categories, and some of those answers included multiracial, Hispanic, Latino, Cuban.
And yes, this data is old. Newer estimates exist, but they have kind of a high margin of error. I’d rather use this solid 2010 data.
Update – this Q got asked: Each dot represents 50 people, pretty much. I took the actual count of people and divided by 50 and rounded the result. Therefore, if there were 25 or more Asian people in a block, for example, the formula rounds up to one, and I draw one blue dot. If there were 24 or fewer people, it rounds down to zero, so no dot.
Update 2 – this Q got asked: Why don’t you show the whole metro area? Well, this map is a free sample of what I seek to get paid to do more often: make maps and data visualizations. So here’s my pitch: Hire me for dataviz. I can do a map like this for a larger area, a different area, or other stuff altogether.
Apologies to Radical Cartography, where I got this dot density idea from.
And, I’m just one person without a copyeditor or colleague. If there’s a problem or error on this map, let me know at maggie [dot] a [dot] lee [at] gmail.
