Note the article refuses to say it explicitly, you have to dig deeper into the footnotes, but the group that is gaining the most “switchers” (after athiesm/agnosticism) is Islam.

> The U.S. and Kenya have the highest levels of “accession,” or entrance, into Islam, with 20% of U.S. Muslims and 11% of Kenyan Muslims saying they were raised in another religion or with no religion. That said, overall, Muslims are a minority in both places: About 1% of U.S. adults and 11% of Kenyans currently identify as Muslim.
