Little TIME article I stumbled across:
https://content.time.com/time/subscriber/article/0,33009,819765,00.htmlThe Herald's estimates, summarized in a report by Author Will Oursler: as against 1,071,897 people converted to Catholicism during the last ten years (most of them presumably ex-Protestants), some 4,000,000 Roman Catholics have become Protestants.
And...note the date it was originally published. Wow.
Kind of undermines one of the Atlas talking points commonly used in the past here that people may regularly often leave Catholicism
now but in the past this basically NEVER happened which I always thought was weird...there's notable examples of people converting Catholic->Protestant in the 19th Century like Thomas Nast.
Anyway just an interesting little piece to come across.
