How has membership changed in the largest U.S. religious bodies? The previous post was a bit data-heavy so I’ve created a slightly different version that shows more clearly what occurred in American church participation from 1990-2010.
Below is a list of reported membership totals for the largest groups, in five-year increments from 1990-2010, also from the Association of Religion Data Archives (ARDA).
The data below are different because they show “membership” figures where the previous was reported “attendance.” For some groups the totals are very close and for others not close at all. (Please see the “Notes” at bottom). But there is only one major discrepancy, and overall the data show the same trend.
