“Protestant apologist Javier Perdomo has also done of a deep dive on the Pew study and shows that there isn’t a colossal shift among Protestants in becoming Catholic. Among those raised Protestant only two percent now identify as Catholic whereas among those raised Catholic, 14% of them identify as Protestant. That means there are seven times as many converts to Protestantism than there are to Catholicism between the two groups.”
