“…In addition, studies of religion and fertility have focused almost exclusively on completed family size as the outcome of interest. The timing of first birth has been relatively neglected, although it carries significant consequences for women's socioeconomic attainment and long‐term health and well‐being, along with the health and well‐being of their children (Augustine, Prickett, Kendig, & Crosnoe, ; Loughran & Zissimopoulos, ; Royer, ; Williams, Sassler, Addo, & Frech, ). As women who have earlier first births are likely to have more births overall (Mills, Rindfuss, McDonald & te Velde, ; Rindfuss, Morgan, & Swicegood, ), studying the relationships between religion and the timing of first birth may additionally help us anticipate how macro‐level religious change might affect population growth or decline.…”
