ARDA Longitudinal Religious Congregations and Membership File, 1980-2010 with Estimates for Missing Data

"This dataset is a longitudinal version of the Churches and Church Membership in the United States studies from 1980 and 1990, and the Religious Congregations and Membership Studies from 2000 and 2010. It contains the adherent and congregation counts of 302 religious groups that participated in at least one of the 1980-2010 data collections. 

It is very important to understand how this file differs from its standalone counterparts, and its many limitations. Using these data for over-time comparisons without reading any documentation will likely result in inaccurate statistics. Data users are strongly urged to read the paper by Rachel Bacon, Roger Finke and Dale Jones that details all the changes made when creating the longitudinal file. Major changes made to the file include new variable naming schemes, new combined religious groups that correct for schisms and mergers, new adherent counts for the United Methodist Church, and count estimates for missing data among 40 groups. Users can download the paper here. Users can download the appendices here: Appendix A, Appendix B, Appendix C." [Read more].
