This research explores factors which differentiate non-institutionalized elderly persons living alone, living only with a spouse, and living with other persons (with or without a spouse present). Special attention is devoted to the measurement and investigation of several social norms and personal preferences. These factors are organized in terms of a decision-making framework developed from micro-economic and demographic theory. Choice of a living arrangement is seen as the product of underlying norms and preferences, a set of socio-demographic factors, and constraints on choice. This research relies on data from 454 personal interviews drawn from a stratified random sample of persons 65 and over living in private households in London, Ontario, Canada.
Data analysis indicates that the decision of whom to live with is complex and is influenced by a large group of variables. However, the most important factors are the social norms and personal preferences of the respondents. Of these, a preference for independence and privacy surfaces as the strongest predictor of living arrangements. Being able to do what one wants without outside interference in conjunction with a private living style tends to be viewed by older persons as very important household ‘goods’. The expected separateness of the elderly, age segregation or differentiation, and kinship obligations and ties were found to be influential social norms affecting living arrangement decisions. The analysis also suggests that the constraining effects of domestic competence, physical strength and mobility, and availability of kin for co-residence are also important. In addition, several socio-demographic variables including age, sex and ethnicity arise as significant predictors of living arrangements.
