Yearning , learning and conceding : ( Some of ) the reasons people change their childbearing intentions

People’s childbearing intentions change over their lives. These changes are sometimes conceptualised as a response to constraints such as the biological clock or lack of a partner. However, we find that they are influenced by a much wider range of factors: social norms; adaptation to the wishes of a partner; re-partnering; and learning about the costs and benefits of parenthood. In a departure from existing studies we analyse increases in planned fertility separately from decreases; we conclude that the determinants of increases in planned fertility are not simply equal and opposite to the determinants of decreases.
