A quick overview is available here. This is an update of the 1952, 1971, 1980, 1990, and 2000 studies originally done by the
National Council of Churches and the
Glenmary Research Center. Since 1990, the
Association of Statisticians of American Religious Bodies (ASARB)
has sponsored the studies.
Each participating religious body supplies the number of churches, full members, adherents, and attendees for each
county. See
"Data Collected" for more information. Our data collection
office can assist any group with compiling their data to the county level.
The study coincides with the US census. National polls rarely give any religious data below the national level.
This study gives a picture of county-level religious affiliation nationwide. The longevity of the study helps to
identify trends and track religious change.
Online reports from the
2010 U.S. Religion Census can be obtained for various geographies free of charge from
The Association of Religion Data Archives (ARDA). ARDA also
archives the previous datasets and makes them available for download.
The book includes data tables, documentation, 32 pages of color maps and charts, and a wall map of religious families by county.
It can be ordered at 1-800-877-0700 or
