Ø A decline in marriages that occur after the woman is pregnant.
“Some of this might seem contradictory. Why would both the number of abortions and of out-of-wedlock births go up? If there were more illegitimate births, why were fewer children available for adoption?” said Lott.
Mr. Lott answers the question by saying that, “part of the answer lies in attitudes to premarital sex. With abortion seen as a backup, women as well as men became less careful in using contraceptives as well as more likely to have premarital sex.”
“But all these changes--rising out-of-wedlock births, plummeting adoption rates, and the end of shotgun marriages--meant one thing: more single parent families. With work and other demands on their time, single parents, no matter how "wanted" their child may be, tend to devote less attention to their children than do married couples; after all, it's difficult for one person to spend as much time with a child as two people can.”
“From the beginning of the abortion debate, those favoring abortion have pointed to the social costs of "unwanted" children who simply won't get the attention of "wanted" ones. But there is a trade-off that has long been neglected. Abortion may eliminate "unwanted" children, but it increases out-of-wedlock births and single parenthood. Unfortunately, the social consequences of illegitimacy dominated,” Mr. Lott said.
Addressing the current situation Mr. Lott wrote, “children born after liberalized abortion rules have suffered a series of problems from problems at school to more crime. The saddest fact is that it is the most vulnerable in society, poor blacks, who have suffered the most from these changes.”

“Liberalized abortion might have made life easier for many, but like sex itself sometimes, it has had many unintended consequences.”
