“…We specifically consider the five largest religious groups: evangelical Protestants (27% of the sample), Catholics (26%), mainline Protestants (16%), black Protestants (7%), and secular Americans (23.5%, and the reference category for most of our analyses). Following other scholars’ lead (e.g., Blouin, Robinson, and Starks 2013), we dropped from our analyses respondents who fell into Steensland, Robinson, and Wilcox's “other” category, which combines traditions as diverse as Judaism, Mormonism, Hinduism, and Islam. As a second modification for conceptual clarity, we identified respondents as non-religious seculars only if they met Steensland, Robinson, and Wilcox's definition of being unaffiliated (i.e., identified as atheist, agnostic, or “nothing in particular”), and also indicated that they neither saw religion as “important in their life,” nor prayed on a regular basis.…”
