Source

The 1980 data were collected by the Glenmary Research Center and includes statistics for 111 Judeo-Christian church bodies, including number of churches and adherents. These data originally appeared in Churches and Church Membership in the United States, 1980, published by the Glenmary Research Center.

The adherence rate provides the number of adherents of a particular group per 1,000 population. For example, in 2000 the Episcopal Church had an adherence rate of approximately 8 (8.1) in Autauga County, Alabama. This means that 8 out of every 1,000 people in Autauga County are Episcopalian.
