| Abstract: | What motivates adult children, parents, and even grandchildren to live together? To answer this question, we review the sociological and social gerontological research on multigenerational households and families. We first provide a snapshot of multigenerational coresidence in the US and then discuss the primary theoretical perspectives used to explain these patterns: exchange theory, altruism, and norms and obligations. Structural conditions including economic crises tend to facilitate adult children moving in with parents (often with dependent children in tow), while spousal loss and declining health act as catalysts for parents moving in with adult children. Furthermore, economic struggles often facilitate the formation of grandparent-headed families where the middle generation parents may or may not be present. We suggest that the current economic recession and housing crises will have profound effects on multigenerational households and may also encourage more coresidence. Changes in social welfare policies, increases in coresident grandparenting, and changes in the racial and ethnic composition of the US also have implications for multigenerational households’ economic and social security. |
