Christian Science is generally estimated to have about 400,000 followers in the U.S. , though older estimates have been higher and the exact number is hard to pin down because the church does not publish a current official membership count. A much older church estimate from the 1890s put U.S. membership at 8,724, but that is far out of date.

What that means

  • Modern reporting suggests the U.S. Christian Science population is small and declining.
  • Public sources often use estimates rather than exact counts because membership is not tracked in a way that produces a widely accepted current total.
  • If you want a single practical figure for a quick answer, “roughly 400,000 in the U.S.” is the best public estimate I found.

Context

Christian Science has also seen a long-term decline in churches and readership, which matches the smaller follower estimate. That said, some older sources described the movement as much larger, so numbers can vary depending on the year and the definition of “follower”.

Would you like the estimate split into U.S. followers, church members, and active congregations?
