Religious Statistics: Reference Books and Other Resources

1. Current Data

[Ref. BR513.Y42 (back issues in stacks)] Yearbook of American and Canadian Churches. Nashville, Tenn.: Abingdon Press, 1973-.

Contains statistical data based on reports from U.S. and Canadian denominations; in 1996, 99 U.S. and 49 Canadian religious bodies contributed data. Not every denomination reports annual figures, and each denomination determines its own statistical criteria. Detailed information is included only for religious groups which identify themselves as distinctively Christian; the yearbook is published under the auspices of the National Council of Churches of Christ. Reported data includes membership figures, financial contributions (both as percentage change from last year and as raw numbers), per capita contribution levels, and the number of congregations, clergy, and Sunday schools. The yearbook also tracks seminary enrollment, including tables for women and ethnic minorities from data supplied by the Association of Theological Schools.
