This article reviews the current literature regarding living arrangements among older adults in the United States. The reasons for studying living arrangements are outlined and the aggregate trends are summarized. Then, the two commonly used conceptual models in this area of research are presented. These models identify the individual level characteristics that influence living arrangements in later life. It is argued that a more dynamic perspective is needed to explain the living arrangement transition process. This perspective builds on Lawton's person-environment theory and relies on longitudinal data analysis. Finally, directions for future research are discussed.
