How many people in the US practice the Christian religion?

It is difficult to determine exactly how many individuals in the United States practice the Christian religion. According to the latest data from the Pew Research Center, about 71 percent of Americans identify as Christian. This includes members of various denominations, such as Protestantism, Catholicism, and Mormonism. This number has been steadily declining in recent years, from 78 percent in 2007 to 71 percent in 2018. Additionally, the proportion of non-Christian Americans has risen from 16 percent in 2007 to 22 percent in 2018. While this data suggests that the number of Americans practicing Christianity is still majority, it is clear that the Christian population is declining.
