Gallup poll in the context of "George Gallup"

Christianity is the predominant religion in the United States, although estimates vary among sources. According to a 2024 Gallup survey, approximately 69% of the U.S. population—about 235 million out of 340 million people—identify as Christian. A plurality of Americans identify as Protestant (45%), followed by Roman Catholics (22%). Smaller Christian groups include members of the Church of Jesus Christ of Latter-day Saints (1.5%), Eastern Orthodox Christians (0.5%), and other Christian denominations (0.4%). The United States currently has the largest Christian population in the world and, more specifically, the largest Protestant population globally, comprising nearly 235 million Christians and approximately 153 million adherents of Protestant denominations. However, while the U.S. leads in absolute numbers, several other nations have a greater proportion of their populations identifying as Christian.

The Public Religion Research Institute's "2020 Census of American Religion", carried out between 2014 and 2020, showed that 70% of Americans identified as Christian during this seven-year interval. In a 2020 survey by the Pew Research Center, 65% of adults in the United States identified themselves as Christians. They were 75% in 2015, 70.6% in 2014, 78% in 2012, 81.6% in 2001, and 85% in 1990. About 62% of those polled claim to be members of a church congregation. The 2023-2024 Pew Religious Landscape Survey in the United States found that 40% identitied as Protestant and 19% as Catholic.
