|The Religious Congregations Membership Study 2012 (RCMS) is a county-by-county enumeration of religious bodies in the US. It 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. Our data collection office can assist any group with compiling their data to the county level.This study will give a picture of county-level religious affiliation nationwide. The longevity of the study helps to identify trends and track religious change.
