Abstract
Changes in marital fertility have accounted for 83 percent of the decline in total fertility since 1971; changes in marital status accounted for 19 percent, and changes in nonmarital fertility had only a negligible effect. Declines in the level of marital fertility account for a substantial part of the overall decrease; postponement of childbearing did not occur in any significant degree until the 1970s.
摘要
自1971年以来，婚姻生育率的变化占总生育率下降的83%；婚姻状况的变化占19%，非婚生育率的变化影响微乎其微。婚姻生育率水平的下降在总体下降中占很大一部分；直到20世纪70年代才出现显著的生育推迟现象。
