The Census does not ask questions about religion, but that data is collected by the Association of Religious Data Archives (ARDA). They have 2010 data in map form, but it's only by state. There is county data in the GIS mapping tool for 2009. In either case there is no map that shows the largest denomination like the 2000 data does. One could construct it from the tables on their site.
You mean like this map already posted in this thread?
I see these maps in a lot of places, but is there ever going to be an updated version based on the 2010 Census?
I do get a kick out of Newberry County be a lone spot of Lutheran strength in the South. That's due of course to the area being settled mainly by Germans during the Colonial era. Lexington County north of the fall line was also settled mainly by Germans, but it's had a lot more in-migration since then than Newberry, tho you still see the German influence in the last names of a lot of the influential people with roots in the community.
