We revisit the discussion on family limitation through stopping and spacing behavior before and during the fertility transition with a sample of 12,800 settler women's birth histories in nineteenth- and twentieth-century South Africa. Using cure models that allow us to separate those who stop childbearing from those who continue, we find no evidence of parity-specific spacing before the transition. We do find evidence of non-parity-based birth postponement before the transition. Increased stopping and parity-independent postponement characterized the beginning of the fertility transition, with increased parity-specific spacing following later in the transition phase.

停止！去！我们可以从1835-1950年在南非塞特勒的出生时间中学到什么计划生育？

我们通过在19世纪和20世纪南非的12,800名定居妇女的生育史样本，通过在生育力过渡之前和期间停止和间隔行为来回顾关于家庭限制的讨论。通过使用治愈模型，我们可以将不再生育的人与继续生育的人区分开，在过渡之前，我们没有发现特定于奇偶性间隔的证据。我们确实找到了过渡之前非基于奇偶校验的出生推迟的证据。停止的增加和不依赖于奇偶性的推迟的特征是生育力过渡的开始，而在过渡阶段的后期跟随着奇偶性特定的间隔的增加。
