Totals (Unadjusted)*: 4,458 5,118,438
Total (Adjusted)**:   6,561,960

The population of these 13 counties (or equivalents) in 1990 was 8,239,820; in 2000 it was 9,157,540. The total population changed 11.1%. The unadjusted adherent totals of the religious groups listed above (5,118,438) include 55.9% of the total population in 2000. The adjusted total adherents (6,561,960) include 71.7% 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.

**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.
