The availability of abortions on demand, as provided by the new New York State abortion law, had a profound effect on fertility in a large community with previously very restricted access to illegal abortions. Improved family planning and the availability of abbortions as a backup measure combines with a preference for a smaller family size led to a one-third reduction of live births in the short period since the new law became effective. Planning for paediatric and obstetric care had to be adjusted accordingly. The frequently hypothesized or reported secondary effects on illegitimacy or infant mortality could not be observed. The trend towards increasing illegitimacy was slowed down, but not reversed. Infant mortality continued its short-term erratic pattern; the trend towards a higher proportion of teenage pregnancies cancelled the effect that pregnancies at higher risk for infant death are also at higher risk for abortion.
纽约州新堕胎法规定按需提供堕胎服务，这对一个此前非法堕胎渠道极为有限的大型社区的生育率产生了深远影响。计划生育的改善以及堕胎作为一种备用措施的可及性，再加上对小家庭规模的偏好，导致自新法律生效后的短时间内活产数量减少了三分之一。儿科和产科护理规划不得不相应调整。未观察到对非婚生子女或婴儿死亡率的常见假设或报道的次生影响。非婚生子女增加的趋势有所放缓，但并未逆转。婴儿死亡率继续呈现短期的不稳定模式；青少年怀孕比例上升的趋势抵消了婴儿死亡风险较高的怀孕同时堕胎风险也较高所产生的影响。
