Opaqueness

Much to my surprise, my posting the data below, on January 15, has led to such an interesting array of posts.  So I'm posting the data again.  But why?  I wish I weren't so opaque--especially to myself!  :-)

 

Data on "Total U.S. Population" from October 2008 survey by the Pew Research Center for the People & the Press. All other data from the Pew Forum's U.S. Religious Landscape Survey. For question wording, see the survey topline.

¹"Other Faiths" includes Unitarians and other liberal faiths, New Age groups and Native American religions.
