VPR Note: The chart shows the results of the CIRP Survey administered to Vanderbilt Freshmen every year. VPR received this data from the Office of Religious Life while conducting our political survey of undergraduates (we used it to generate survey weights to address the discrepancy in religious affiliation between our sample and the campus). Though the data have obvious limitations (such as non-differentiation between Hindus, Muslims, Sikhs, and Buddhists), they illustrate some important trends: a longstanding decline in Protestant affiliation since the 1970s and increases in the non-Christian and religiously unaffiliated populations.
