Abstract

This study examines family planning dynamics globally, highlighting the stark differences between developed and developing economies, particularly concerning the "Dual Income, No Kids" (DINK) lifestyle. Analyzing data from 1980 to 2019, for various economies, it finds the DINK choice mainly in developed nations, correlating with higher Human Development Index (HDI) scores and preferences for childlessness or delayed parenthood. This reflects a shift towards valuing personal autonomy, career growth, and financial stability over traditional parenting roles. In contrast, developing economies show minimal adoption of the DINK lifestyle, as economic, cultural, and policy factors still promote traditional family models. This contrast underscores the complex relationship between economic development, societal norms, and family planning, indicating that trends in developed countries are not globally mirrored. The study advocates for policy frameworks that recognize these differences and support diverse family structures, calling for policies that cater to varying family planning preferences and address economic and societal factors shaping these decisions. This approach offers a more nuanced discourse on demographic changes, revisiting J.S. Mill’s "Malthusian lesson" within current socio-economic contexts.
