Map geeks beware!

This is a new mapping feature from the US Census that helps to visualize some of the data from their American Community Survey.


You can make Pittsburgh pretty in polka dots

Not only is the info pretty fascinating, the design of the interactive mapping feature is fabulous.  You can easily toggle between years, datasets, and geography, while customizing the coloration and visualization.

You can see data visualized for population, 65 and older, education, working, owner occupied, immigration, and income.¬†Particularly surprising in Pittsburgh is the 22 year difference (1990-2012) in “Foreign Born” residents.

Not sure when this was made, mid 1800s? It looks like it was created by Fredrick Law Olmstead’s planning company, who you may know from such places as Central Park, as well as the town of Vandergrift.

A dot = 200 people.

This is absolutely, incredibly beautiful. I can spend hours digging into this.

From the creator: “a map of every person counted by the 2010 US, 2011 Canadian, and 2010 Mexican censuses. The map has 454,064,098 dots – one for each person.”

Here’s an article link to the background, and a direct link to the actual map.

Dig in and explore North America.

Thank you.
