Kinship is a fundamental and universal form of social structure. All humans belong to kinship structures in the same way that all humans are born and die. Yet, the degree to which individuals benefit from these structures varies largely across subgroups and over age and time.
The term "kinship inequalities" refers to differences in kin presence, availability, and resources for individuals. These disparities arise from a range of factors, including demographic dynamics, socioeconomic inequalities, and societal norms. For example, longer lifespans allow grandparents to spend more time with their grandchildren. This is, potentially, a positive development for grandchildren, grandparents, and parents, who benefit from childcare support. Yet, in practice these gains distribute unevenly among sub-populations that have different legacies of mortality, fertility, and migration.
The Research Group on Kinship Inequalities, funded by the Max Planck Society, conducts research to advance the subfield of kinship demography and the study of kinship inequalities. The group studies how differences in kinship among persons and groups determine individual outcomes and structure human societies. The group has three main objectives:
- to study kinship inequalities by combining classical demographic approaches with new data, methods, and technologies;
- to improve our understanding of fundamental population dynamics by leveraging insights from kinship demography;
- to contribute to the training of scholars in areas related to kinship demography.
The study of kinship has a long tradition in demography, often in the context of analytical family demography. Yet, applying a "kinship lens" to broader social phenomena can produce novel and unexpected insights. The group conducts research on four main substantive areas: (1) kin availability, intergenerational overlap, and transfers; (2) the experience of kin loss and bereavement; (3) the effects of demographic change on family structures; and (4) the implications of these processes for individuals, families, and societies. These are pressing topics as families becomes increasingly diverse and complex, extending beyond biological kin and across national borders.
