The 2010 U.S. Religion Census book includes introductory material that covers many of the procedures used and problems encountered while compiling this collection.
Following the data tables, appendices explain the methodology used by the various groups included in the study. Appendix A includes basic data for all 236 groups. The additional appendices give further details on specific groups or methodologies.

Note: In an effort to better match the ASARB standards for adherents, a few religious bodies changed the way their adherents were reported in 2010. Amish groups, the Catholic Church, Friends groups, Jewish groups, the Church of Jesus Christ of Latter-day Saints, and the United Methodist Church are known to have done so. While this makes comparisons between groups more appropriate in the 2010 study, it does affect comparisons between this and previous studies. Our own comparative maps note this, as do the online reports.
