ThirdWay, a think tank, recently published a study called “The Demographics of Abortion”. They claim that Catholics represent 27% of those having abortions each year, or about 350,000 abortions. Evangelicals account for 13%. That is about 170,000 abortions per year.
There are about 1.3 million abortions per year in America, to 4.1 million live births and 900k miscarriages.
