"Professor Kingsley Davis of the United States Commission on Population Growth and the American Future states that "The current belief that illegitimacy will be reduced if teenage girls are given an effective contraceptive is an extension of the same reasoning that created the problem in the first place. It reflects an unwillingness to face problems of social control and social discipline, while trusting some technological device to extricate society from its difficulties. The irony is that the illegitimacy rise occurred precisely while contraceptive use was becoming more, rather than less, widespread and respectable."[23] The illegitimacy rate for births among teenaged girls hovered around five to seven percent for decades, until about 1960. Between 1960 and 1970, it doubled as the birth control pill helped usher in the 'Sexual Revolution.' After 1970, the teenage illegitimacy rate literally exploded as comprehensive sex education programs and school-based clinics were introduced. The overall illegitimacy rate for all children born in the United States was 5 percent in 1960. This rate has more than quintupled to more than 28%."
