Religion in Colorado

According to the American Religious Identification Survey, conducted in 2001 by The Graduate Center at the City University of New York, Colorado residents surveyed identified their religious identity as follows:

Christian Self-Identifications – 68%
*Roman Catholic – 23%
*Christian – 9%
*Baptist – 8%
*Methodist – 5%
*Lutheran – 5%
*Episcopalian – 3%
*Presbyterian – 3%
*Pentecostal – 2%
*Churches of Christ – 2%
*The Church of Jesus Christ of Latter-day Saints – 2%
*Protestant – 2%
*Jehovah's Witness – 1%
*Seventh-day Adventist – 1%
*Evangelical – 1%
*Non-denominational – 1%
Non-Religious/Atheist/Agnostic – 21%
Buddhist – 1%
Jewish – 1%
Other Religions – 3%
Refused To Answer – 6%

Notably, of the 68% who self-identified as some form of Christian, 23% identified as Roman Catholic, 18% identified with a historically mainline Christian identifier (Methodist, Lutheran, Episcopalian, Presbyterian, Protestant), and the remaining 27% identified with a historically conservative/evangelical Christian identifier (Christian, Baptist, Pentecostal, Churches of Christ, The Church of Jesus Christ of Latter-day Saints, Jehovah's Witness, Seventh-day Adventist, Evangelical, Non-denominational).

There are more people who expressly identify as Non-Religous/Atheist/Agnostic in Colorado than there are people who identify as mainline Christians.

Mainline Christian and non-Christian self-identifications make up about 44% of survey respondents, while Roman Catholics and conservative/evangelical self-identifications make up about 50% of self-identifications. It is safe to guess that at least some non-respondents are Roman Catholic or conservative/evangelical self-identifiers, so that pairing makes up a majority of people in the state to the extent that the survey is accurate.
