"Figure 1 displays the difference in fertility rates between repeal states and states with no law change. The pattern shows that differences were roughly constant through 1970. A sharp drop of about 6% observed in 1971 remained through 1973, indicating that fertility rates fell in repeal states relative to states with no law change during this period. Through 1974/75, the difference narrowed, and beginning in 1976 there were few differences between the states. The relative decline in fertility rates in repeal states occurred in exactly the years in which abortion was legal only in repeal states. The partial rebound in 1974/75 may indicate that abortion access in states affected by Roe v Wade increased less quickly following this decision relative to the rapid introduction of abortion services in repeal states in 1970. (A corresponding figure for reform states vs states with no legal changes showed no obvious difference in fertility rates over time and for purposes of brevity is not displayed here.)"
