Methodology. This table extracts and analyzes a microcosm of the world religion table. It depicts the United States, the country with the largest number of adherents to Christianity, the world's largest religion. Statistics at five points in time from 1900 to 2005 are presented. Each religion's Annual Change for 2000–05 is also analyzed by Natural increase (births minus deaths, plus immigrants minus emigrants) per year and Conversion increase (new converts minus new defectors) per year, which together constitute the Total increase per year. Rate increase is then computed as percentage per year.

Structure. Vertically the table lists 30 major religious categories. The major categories (including nonreligious) in the U.S. are listed with largest (Christians) first. Indented names of groups in the first, "Adherents," column are subcategories of the groups above them and are also counted in these unindented totals, so they should not be added twice into the column total. Figures in italics draw adherents from all categories of Christians above and so cannot be added together with them. Figures for Christians are built upon detailed head counts by churches, often to the last digit. Totals are then rounded to the nearest 1,000. Because of rounding, the corresponding percentage figures may sometimes not total exactly to 100%. Religions are ranked in order of size in 2005.

Christians. All persons who profess publicly to follow Jesus Christ as God and Savior. This category is subdivided into Affiliated Christians (church members) and Unaffiliated (nominal) Christians (professing Christians not affiliated with any church). See also the note on Christians to the world religion table. The first six lines under "Affiliated Christians" are ranked by size in 2005 of each of the six megablocs (Anglican, Independent, Marginal Christian, Orthodox, Protestant, Roman Catholic).

Evangelicals/evangelicals. These two designations—italicized and enumerated separately here—cut across all of the six Christian traditions or ecclesiastical blocs listed above and should be considered separately from them. The Evangelicals (capitalized "E") are mainly Protestant churches, agencies, and individuals who call themselves by this term (for example, members of the National Association of Evangelicals); they usually emphasize 5 or more of 7, 9, or 21 fundamental doctrines (salvation by faith, personal acceptance, verbal inspiration of Scripture, depravity of man, Virgin Birth, miracles of Christ, atonement, evangelism, Second Advent, et al.). The evangelicals (lowercase "e") are Christians of evangelical conviction from all traditions who are committed to the evangel (gospel) and involved in personal witness and mission in the world.

Jews. Core Jewish population relating to Judaism, excluding Jewish persons professing a different religion.

Other categories. Definitions are as given under the world religion table.
