Abstract
Amidst pressing global challenges and internal demographic threats, it is crucial to understand the institutional dynamics shaping the well-being of large families. This study delves into the intricate web of institutional factors that influence the prosperity of such families, examining key theoretical frameworks including institutional theory, human and social capital theories, and concepts of family. The empirical investigation draws upon extensive data sources, encompassing population censuses spanning five decades (1970–2020) and the comprehensive 2021 All-Russian sociological study Demograficheskoe samochuvstvie regionov Rossii [Demographic Well-Being of the Regions of Russia]. We conducted 22 in-depth interviews with members of large families across 10 regions. These interviews gave us a nuanced picture of the trends in family structure and the reasons behind reproductive decisions within these families. While institutional support is viewed as a “bonus” rather than a decisive factor in reproductive decisions, parents require various resources, including material, temporal, socio-psychological, informational, and educational resources, to develop necessary family and human capital skills. Furthermore, the study identifies the institutional conditions and resources crucial for bolstering the well-being of large families as well as the importance of effective family policies.
