If Protestantism is treated as a single religious group, then fully 34% of American adults currently have a religious identity different from the one in which they were raised, which is up six percentage points […]
This appendix details the methods used in this study to project changes in the population size and geographic distribution of eight major religious groups from 2010 to 2050. It is organized in five sections. The first section explains how the baseline (2010) religious composition estimates were derived. The second section describes how key input data […]
