Totals (Unadjusted)*:   18,029 8,417,929  
Total (Adjusted)**:     9,497,381  

The population of these counties (or equivalents) in 1990 was 13,658,776; in 2000 it was 18,172,295. The total population changed 33.0%. The unadjusted adherent totals of the religious groups listed above (8,417,929) include 46.3% of the total population in 2000. The adjusted total adherents (9,497,381) include 52.3% of the population.


*The “Unadjusted Totals” come from the 1990 and 2000 data collected by representatives of the Association of Statisticians of American Religious Bodies (ASARB). While quite comprehensive, this data excludes most of the historically African-American denominations and some other major groups. As a result, these numbers will be an underestimate of the total adherence rate, particularly in areas with a large African-American population. The 2000 data included 149 religious groups and the final results are published in Religious Congregations and Membership in the United States 2000. Copyright © 2002, All rights reserved. The 1990 data included 132 groups and the final results are published in Churches and Church Membership in the United States 1990 Copyright © 1990, All rights reserved. Published by Glenmary Research Center, 1312 Fifth Ave., North, Nashville, TN 37208. [More information on the data collection]

**The “Adjusted Totals” include all adherents in the denominations counted by the Association of Statisticians of American Religious Bodies (ASARB) and estimates adherent totals for the historically African-American denominations and other religious groups not listed in the ASARB totals. An article by Roger Finke and Christopher P. Scheitle (2005) reviews how these estimates were computed.

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.
