Composição, formação e localização de domicílios: um estudo dos domicílios com jovem adulto

Abstract

The main purpose of this thesis is to identify the probability of happening different young adult living arrangements in the urban space due to changes on the young adults characteristics and environmental aspects. From the economic theory of household formation some hypothesis were developed between the household structure and its relation with intra-urban structure. These hypotheses were tested in two models stock and flow by analyzing the effects of demographic, socioeconomic and environmental factors. It is been concluded that household stock occur through young adults living with their parents and family cohabitation, while flow happens through union/ marriage. In some ways stock household categories represent the possibility of a new household formation and the others the materialization of this process. The family cohabitation has more frequency in the low socioeconomic status family, mainly in monoparental families headed by women. This kind of extension confirms the effect of income on the household extension, in other words, lower potential income of household members increases the household size. However the household extension happens in higher socioeconomic status family through young adults living with their parents, contradicting the income effect hypothesis. The answer to this condition can be household price. In the flow model there is the individual income paradox on the couples formation. The probability of couples living in a new households goes on the opposite way of traditional vision that an increase in income induces an increase in union/ marriage. The analyses of environmental aspects show that average income and centrality are related while the intensity land use and accessibility somehow break this socio-spatial organization. Lower commuting time allows the development of scattered the most valued areas. The combination of accessibility and verticalization promotes the household access to lower socioeconomic families near the most valued areas.
