Despite the absence of a link between personal religious devotion and abortion, religious affiliation did have some important influence. Adamczyk found that conservative Protestants were the least likely to report having an abortion, less likely than mainline Protestants, Catholics and women with non-Christian religious affiliations.
Regarding the impact of the religious involvement of a woman’s peers, Adamczyk found no significant influence. However, Adamczyk did find that women who attended school with conservative Protestants were more likely to decide to keep their baby if pregnant in their 20s than during their teen years.
“The values of conservative Protestant classmates seem to have an abortion limiting effect on women in their 20s, but not in their teens, presumably because the educational and economic costs of motherhood are reduced as young women grow older,” Adamczyk said.
