    Learning Objectives
    • Describe the extent and correlates of religious affiliation.
    • Explain the different dimensions of religiosity.

    In many ways, the United States is a religious nation, although it is not more religious than many other nations. In a 2002 international survey conducted by the Pew Research Center, 59% of Americans said that religion is “very important” in their lives, a figure that ranked the United States 29th out of 42 nations. In a 2007 Pew survey conducted in the United States, about 83% of Americans expressed a religious preference, 61% were official members of a local house of worship, and 39% attended religious services at least weekly (Pew Forum on Religion & Public Life, 2008).Pew Forum on Religion & Public Life. (2008). U.S. religious landscape survey. Washington, DC: Pew Research Center.

    Religious Affiliation and Religious Identification

    Let’s look at religious affiliation a bit more closely. Religious affiliation is a term that can mean actual membership in a church or synagogue, or just a stated identification with a particular religion, whether or not someone actually is a member of a church or synagogue. As the figures just listed indicate, more people identify with a religion than actually belong to it. Another term for religious affiliation is religious preference.

    The 2007 Pew survey included some excellent data on religious identification (Figure \(\PageIndex{1}\)). Slightly more than half the public say their religious preference is Protestant, while about 24% call themselves Catholic. Almost 2% say they are Jewish, while 6% state another religious preference and 16% say they have no religious preference. Although Protestants are thus a majority of the country, the Protestant religion includes several denominations. About 34% of Protestants are Baptists; 12% are Methodists; 9% are Lutherans; 9% are Pentecostals; 5% are Presbyterians; and 3% are Episcopalians. The remainder identify with other Protestant denominations or say their faith is nondenominational. Based on their religious beliefs, Episcopalians, Presbyterians, and Congregationalists are typically grouped together as Liberal Protestants; Methodists, Lutherans, and a few other denominations as Moderate Protestants; and Baptists, Seventh-Day Adventists, and many other denominations as Conservative Protestants.

    Correlates of Religious Affiliation

    The religious affiliations just listed differ widely in the nature of their religious belief and practice, but they also differ in demographic variables of interest to sociologists (Finke & Stark, 2005).Finke, R., & Stark, R. (2005). The churching of America: Winners and losers in our religious economy (2nd ed.). New Brunswick, NJ: Rutgers University Press. For example, Liberal Protestants tend to live in the Northeast and to be well educated and relatively wealthy, while Conservative Protestants tend to live in the South and to be less educated and working-class. In their education and incomes, Catholics and Moderate Protestants fall in between these two groups. Like Liberal Protestants, Jews also tend to be well educated and relatively wealthy.

    Race and ethnicity are also related to religious affiliation. African Americans are overwhelmingly Protestant, usually Conservative Protestants (Baptists), while Latinos are primarily Catholic. Asian Americans and Native Americans tend to hold religious preferences other than Protestant, Catholic, or Jewish.

    Age is yet another factor related to religious affiliation, as older people are more likely than younger people to belong to a church or synagogue. As young people marry and “put roots down,” their religious affiliation increases, partly because many wish to expose their children to a religious education. In the Pew survey, 25% of people aged 18–29 expressed no religious preference, compared to only 8% of those 70 or older.


    People can belong to a church, synagogue, or mosque or claim a religious preference, but that does not necessarily mean they are very religious. For this reason, sociologists consider religiosity, or the significance of religion in a person’s life, an important topic of investigation.

    Religiosity has a simple definition but actually is a very complex topic. What if someone prays every day but does not attend religious services? What if someone attends religious services but never prays at home and does not claim to be very religious? Someone can pray and read a book of scriptures daily, while someone else can read a book of scriptures daily but pray only sometimes. As these possibilities indicate, a person can be religious in some ways but not in other ways.

    For this reason, religiosity is best conceived of as a concept involving several dimensions: experiential, ritualistic, ideological, intellectual, and consequential (Stark & Glock, 1968).Stark, R., & Glock, C. Y. (1968). Patterns of religious commitment. Berkeley: University of California Press.Experiential religiosity refers to how important people consider religion to be in their lives. Ritualistic religiosity refers to the extent of their involvement in prayer, reading a book of scriptures, and attendance at a house of worship. Ideological religiosity involves the degree to which people accept religious doctrine and includes the nature of their belief in a deity, while intellectual religiosity concerns the extent of their knowledge of their religion’s history and teachings. Finally, consequential religiosity refers to the extent to which religion affects their daily behavior.

    National data on prayer are perhaps especially interesting (see Figure \(\PageIndex{3}\)), as prayer occurs both with others and by oneself. Almost 60% of Americans say they pray at least once daily outside of religious services, and only 7% say they never pray (Pew Forum on Religion & Public Life, 2008).Pew Forum on Religion & Public Life. (2008). U.S. religious landscape survey. Washington, DC: Pew Research Center. Daily praying is more common among older people than younger people.

    When we try to determine why some people are more religious than others, we are treating religiosity as a dependent variable. But religiosity itself can also be an independent variable, as it affects attitudes on a wide range of social, political, and moral issues. Generally speaking, the more religious people are, the more conservative their attitudes in these areas (Adamczyk & Pitt, 2009).Adamczyk, A., & Pitt, C. (2009). Shaping attitudes about homosexuality: The role of religion and cultural context. Social Science Research, 38(2), 338–351. An example of this relationship appears in Table \(\PageIndex{1}\), which shows that people who pray daily are much more opposed to homosexual sex. The relationship in the table once again provides clear evidence of the sociological perspective’s emphasis on the importance of social backgrounds for attitudes.

    Table \(\PageIndex{1}\): Frequency of Prayer and Belief That Homosexual Sex Is “Always Wrong. ”Source: Data from General Social Survey, 2010
    Several times a day Once a day Several times a week Once a week Less than once a week Never
    Percentage saying “always wrong” 65.2 49.5 40.8 43.3 34.0 17.0

    Religiosity and College Students

    The Higher Education Research Institute (HERI) at the University of California, Los Angeles, conducted a national longitudinal survey during the last decade of college students’ religiosity and religious beliefs (Astin, Astin, & Lindholm, 2010).Astin, A. W., Astin, H. S., & Lindholm, J. A. (2010). Cultivating the spirit: How college can enhance students’ inner lives. Hoboken NJ: Jossey-Bass. They interviewed more than 112,000 entering students in 2004 and more than 14,000 of these students in spring 2007 toward the end of their junior year. This research design enabled the researchers to assess whether and how various aspects of religious belief and religiosity change during college. Several findings were notable.

    • First, religious commitment (measures of the students’ assessment of how important religion is to them) stayed fairly stable during college. Students who drank alcohol and partied the most were more likely to experience a decline in religious commitment, although cause and effect here are difficult to determine.
    • Second, religious engagement (measures of religious services attendance, praying, religious singing, and reading sacred texts) declined during the college years. This decline was especially steep for religious attendance. Almost 40% of juniors reported less frequent attendance than during their high school years, while only 7% reported more frequent attendance.
    • Third, religious skepticism (measures of how well religion explains various phenomena compared to science) stayed fairly stable. Skepticism tended to rise among students who partied a lot, went on a study-abroad program, and attended a college with students who were very liberal politically.
    • Fourth, religious/social conservatism (views on such things as abortion, casual sex, and atheism) tended to decline during college, although the decline was not at all steep. This set of findings is in line with the research discussed earlier showing that students tend to become more liberal during their college years. To the extent students’ views became more liberal, the beliefs of their friends among the student body mattered much more than the beliefs of their faculty.
    • Fifth, religious struggle (measures of questioning one’s religious beliefs, disagreeing with parents about religion, feeling distant from God, and the like) tended to increase during college. This increase was especially high at campuses where a higher proportion of students were experiencing religious struggle when they entered college. Students who drank alcohol and watched television more often and who had a close friend or family member die were more likely to experience religious struggle, although cause and effect are again difficult to determine.


    • The United States is a fairly religious nation, with most people expressing a religious preference. About half of Americans are Protestants and one-fourth are Catholics.
    • Religiosity is composed of several dimensions. Almost 60% of Americans say they pray at least once daily outside of religious services.
    • Generally speaking, higher levels of religiosity are associated with more conservative views on social, moral, and political issues.

    For Your Review

    1. Do you consider yourself religious? Why or why not?
    2. Why do you think religiosity is associated with more conservative views on social, moral, and political issues? What is it about religiosity that helps lead to such beliefs?
