One of the subdisciplines of Christian apologetics is creation apologetics and there has been a corresponding proliferation/dissemination of [[creation science|creation apologetics]] which has had an significant effect on Christendom (see: [[Global creationism]] and [[Global creationism#History of the growth of creationism and its effect on Christendom|History of the growth of creationism and its effect on Christendom]]).
=== Retention rate of atheist population atheists ===
In 2012, a [[Georgetown University]] study was published indicating that in the United States only about 30 percent of those who grow up in an [[Atheism|atheist]] household remain atheists as adults.<ref>[http://www.christianpost.com/news/study-atheists-have-lowest-retention-rate-compared-to-religious-groups-78029/ Study: Atheists Have Lowest 'Retention Rate' Compared to Religious Groups]</ref> According to Dr. Mark Gray, "of those raised as atheists, 30% are now affiliated with a [[Protestantism|Protestant]] denomination, 10% are Catholic, 2% are Jewish, 1% are Mormon, and 1% are Pagan."<ref>[http://www.christianpost.com/news/study-atheists-have-lowest-retention-rate-compared-to-religious-groups-78029/ Study: Atheists Have Lowest 'Retention Rate' Compared to Religious Groups]</ref>
Furthermore, a tremendous amount of people in atheistic [[Communism|communist]] countries or former communist countries have become Christians and this is still occurring.
