Our chapter on civic culture emphasizes the
role of religion in American public life, while our chapter on
federalism notes many differences among the states. These two themes come together in a new
Gallup survey:
Mississippi is the most religious U.S. state, and is one of eight states where Gallup classifies at least half of the residents as "very religious." At the other end of the spectrum, Vermont and New Hampshire are the least religious states, and are two of the five states -- along with Maine, Massachusetts, and Alaska -- where less than 30% of all residents are very religious.
Gallup classifies 40% of Americans nationwide as very religious -- based on their statement that religion is an important part of their daily life and that they attend religious services every week or almost every week. Another 32% of Americans are nonreligious, based on their statement that religion is not an important part of their daily life and that they seldom or never attend religious services. The remaining 28% of Americans are moderately religious, because they say religion is important but that they do not attend services regularly or because they say religion is not important but still attend services.
Religiosity varies widely across U.S. states and regions, with Mississippi in the deep South and Vermont in New England providing the most extreme example of the disparity. Fifty-nine percent of Mississippians are very religious and 11% nonreligious, while 23% of Vermonters are very religious and 58% are nonreligious. Although New Hampshire ties Vermont with 23% of its residents classified as very religious, slightly fewer (52%) residents in the Granite State are classified as nonreligious.
