Federal and State Government Information: Sources for Data on Religion

The Hekman Library is a depository for federal and state government information in a variety of formats.

Census Buream Statement on Religion


The Bureau of the Census collected information in the Census of Religious Bodies from 1906-1936. This information was obtained from religious organizations.

Public Law 94-521 prohibits us from asking a question on religious affiliation on a mandatory basis; therefore, the Bureau of the Census is not the source for information on religion.

Some statistics on religion can be found in the Statistical Abstract of the United States, the section on Population.

The Hekman Library owns the most current Statistical Abstract, also known as the National Data Book (2017), and it can be accessed online through our catalog.
