A new Pew report has been released, offering insights into why some people stay with their religion and others leave. The report's findings suggest that regional differences in religiosity exist, with southerners tending to be more religious than other us adults, although they are less religious than in the past. The study's results have been summarized by various outlets, but the specific factors influencing individuals' decisions to stay with or leave their faith are not uniformly detailed across the reports.
