This makes it possible to paint demographic and religious profiles of numerous denominations that cannot be described by smaller surveys.
The most recent Religious Landscape Study also was designed to obtain a minimum of 300 interviews with respondents in each state and the District of Columbia as well as to represent the country’s largest metropolitan areas, enabling an assessment of the religious composition not just of the nation as a whole, but also of individual states and localities. adults are not reachable by telephone or do not speak English or Spanish well enough to participate in the survey.
The new survey indicates there are about 51 million Catholic adults in the U. And, unlike Protestants, who have been decreasing as a share of the U. public for several decades, the Catholic share of the population has been relatively stable over the long term, according to a variety of other surveys (see Appendix C).
(Explore the data with our interactive database tool.) To be sure, the United States remains home to more Christians than any other country in the world, and a large majority of Americans – roughly seven-in-ten – continue to identify with some branch of the Christian faith.But the major new survey of more than 35,000 Americans by the Pew Research Center finds that the percentage of adults (ages 18 and older) who describe themselves as Christians has dropped by nearly eight percentage points in just seven years, from 78.4% in an equally massive Pew Research survey in 2007 to 70.6% in 2014.Of the major subgroups within American Christianity, mainline Protestantism – a tradition that includes the United Methodist Church, the American Baptist Churches USA, the Evangelical Lutheran Church in America, the Presbyterian Church (U. A.) and the Episcopal Church, among others – appears to have experienced the greatest drop in absolute numbers.In 2007, there were an estimated 41 million mainline Protestant adults in the United States.And evangelical Protestants, while declining slightly as a percentage of the U. public, probably have grown in absolute numbers as the overall U. That is an increase of roughly 2 million since 2007, though once the margins of error are taken into account, it is possible that the number of evangelicals may have risen by as many as 5 million or remained essentially unchanged.
Like mainline Protestants, Catholics appear to be declining both as a percentage of the population and in absolute numbers. But taking margins of error into account, the decline in the number of Catholic adults could be as modest as 1 million.Forthcoming reports will describe the Religious Landscape Study’s findings about the religious beliefs and practices of “nones” and other groups.For more details on the exact questions used to measure religious identity, see the survey topline. Moreover, these changes are taking place across the religious landscape, affecting all regions of the country and many demographic groups. adults who do not identify with any organized religion is growing, according to an extensive new survey by the Pew Research Center.Racial and ethnic minorities now make up 41% of Catholics (up from 35% in 2007), 24% of evangelical Protestants (up from 19%) and 14% of mainline Protestants (up from 9%).
