The mission of the GRC is to place meaningful information in the hands of its constituents. We disseminate this research in three primary formats: books, maps (learn more about Glenmary's mapping heritage) and data files. Some of these resources are now available for ordering over the Web.

Religious Congregations and Membership Study

Since the 1970s, the Glenmary Research Center has published the results of the Religious Congregations and Membership in the United States Study. This every-10-year study is conducted at the same time as the U.S. Census in cooperation with the Association of Statisticians of American Religious Bodies (ASARB) and other participating religious groups.

This study provides the most complete data available anywhere on U.S. religious affiliation. In fact, the U.S. Census Bureau Web site directs people with questions about religion to the Glenmary Research Center, the most complete and exhaustive data on the number of churches and church members in the United States.

Beginning with the 2010 study, Glenmary will only be responsible for supplying and distributing the Catholic data collected for the study. The complete study is expected to be published in the summer of 2012.
