The Catholic Church does not allow birth control either. The want to promote birth of more Catholics. Interesting factoid, the largest number of converts to Atheism or non belief come from Catholicism. There have been efforts to have the contraceptive view officially changed given the severe Zika danger in Latin America. On the other hand in the US, most Catholics do use birth control.
Interesting factoid, but believable. The road of Catholicism isn't very wide or tractable. It IS the "straight and narrow." But, then we weren't promised anything different in this earthly life, were we?
As for your "most Catholics use birth control" statement, that sounds like something from a mainstream media byte, unreliable but MOST desirable to be believed. It was probably from one of many of those "interviews" that is also MOST desirable to be believed.
However, any first-year statistics student will tell you ALL about the unreliability of the "interview method," that is, THE most unreliable method of gleaning knowledge information.
