Recovering the lost: Remeasuring US religious affiliation

Over the past several decades, survey research has found a growing percentage of Americans claiming no religious affiliation. In this article, we introduce a modified religious traditions (RELTRAD) typology to measure religious affiliation. The approach benefits from a more detailed data collection and coding scheme of religious tradition based upon religious family, denomination, and congregation. Using new national survey data from the Baylor Religion Survey, we find: (1) improvement to survey design and measurement makes it possible to accurately locate more Americans within established religious traditions; (2) Americans remain connected to congregations, but less so to denominations or more generic religious identity labels; and (3) religious adherents are considerably more evangelical than prior studies have found. Finally, we consider how affiliation as a form of religious belonging relates to religious beliefs and behaviors.
