and denominations)." The "Maps and Reports" section provides
access to state, county, and selected metropolitan area level data
and maps on churches by denomination and the number of adherents
for the years 1980 and 1990. The data were summarized from surveys
conducted by the Church Growth Research Center, Church of the
