Neither the level of AFDC benefits nor the AFDC acceptance rate appear to serve as economic incentives to out-of-wedlock childbearing; nor does the availability of contraception and abortion seem to encourage teenagers to initiate sexual activity. However, the availability of subsidized family planning services does apparently lower pregnancy rates, especially among black teenagers; and the availability of abortion seems to reduce substantially the incidence of out-of-wedlock childbearing, especially among whites.
对有子女家庭的援助福利水平和该援助的接受率似乎都不是非婚生育的经济诱因;避孕和堕胎服务的可获得性似乎也不会促使青少年开始性行为。然而,有补贴的计划生育服务的可获得性显然会降低怀孕率,尤其是在黑人青少年中;堕胎服务的可获得性似乎会大幅降低非婚生育的发生率,尤其是在白人中。
