This paper compares the determinants of living alone among elderly women in six countries (Tanzania, Kyrgyzstan, Indonesia, Brazil, Spain, and Sweden) with very different family systems, policy contexts, levels of development, and socio‐economic characteristics. Different factors behind the residential choices of elderly women are estimated by means of logistic regression. Decomposition models are used to assess the extent to which observed differences between countries correspond to specific population compositions or to other factors. Although the importance of all independent variables for living alone is shown to be strong and statistically significant, persistent intercountry disparities in behaviour linked to levels of familism and development remain. Population composition explains only a small part of the observed differences in living alone. Economic development provides an important underlying explanation for the incidence of living alone among women, but many specific differences can also be explained by societal characteristics such as family systems and available policy options.
