Thematic maps on the US Census factfinder

[Willy Woz]

I have had some experience with the factfinder (the new one) but I'm not exactly sure how to access the ancestry options. I would suggest searching on the Association of Religious Data Archives, which although primarily a database studying religion in the US includes a number of maps about census data. Here is a useful link:

The maps are create-your-own, but once you get the hang of it they're pretty easy to generate.
