List of U.S. states and territories by religiosity
The degree of religiosity in the population of the United States can be compared to that in other countries and compared state-by-state, based on individual self-assessment and polling data.
Methodologies
The Gallup Poll assesses religiosityaround the world,[1] asking "Is religion important in your daily life?" and in the United States by state, asking the degree to which respondents consider themselves to be religious. The Pew Research Center and Public Religion Research Institute have conducted studies of reported frequency of attendance to religious service.[2] The Harris Poll has conducted surveys of the percentage of people who believe in God.[3]
