The population of the United States in 1980 was 225,011,986. The adherent totals of the religious groups listed above (110,718,180) include 49.2% of the total population in 1980.

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.
