Introduction Brazil's rapid development has led to profound social and economic stresses. With a Gini index of 60.7 it is one of the world's most unequal countries; the poorest 20% share just 2% of the nation's income. A third of the population lives in extreme poverty, unemployment is high and a quarter of all jobs are in the informal sector. Ten million people are aged 65 and over in Brazil, comprising 6% of the population. (1) Recent governments have sought to improve the lot of older people through progressive non-contributory pension schemes covering both rural and urban populations. Nevertheless, as in many developing countries, older people remain largely dependent upon family support, particularly in the event of the onset of disability. (2) There are no reliable estimates of the number of homeless persons in Brazil. The United Nations Centre for Human Settlements has defined homelessness (2000) in broad terms as a condition of detachment from society characterized by the lack of the affiliative bonds that link people into their social structures. Homelessness carries implications of belonging nowhere rather than simply having nowhere to sleep. Homelessness can thus encompass those living in insecure circumstances as well as hostel dwellers and those forced to sleep without shelter. In Brazil, rural poverty, rural-to-urban migration and income inequality are all likely to contribute to homelessness. The discourse on homelessness in Brazil is currently dominated by the landless rural poor and the plight of street children; the large numbers of urban street-dwellers are given relatively little attention. We investigated pathways into homelessness for older people through a survey of all older residents of public hostels in Rio de Janeiro. Setting and participants Rio de Janeiro has two statutory institutions providing board and lodging for homeless people. Most of the elderly are housed by the Fundacao Leao XIII funded by the state government. Applications for admission may be made by outreach programmes, directly by individuals or by referral from general hospitals. At the time of this survey, they lodged 802 people (567 men and 235 women), of whom 112 (13.9%) were aged 65 years or over. Narratives from open-ended interviews revealed that many of these older hostel residents were isolated, and that they had lived on the margins of society for much of their lives. Typically, they had migrated into Rio from the rural areas of the state or from Brazil's north many years previously. They had lost contact with their families of origin, and most had failed to establish settled ties in Rio. Few had married, and most who had married were divorced. Many had worked in the years leading up to becoming homeless, but in the informal sector. Loss of employment was critical for many participants: some had accommodation that was tied to their work and when they lost their work they lost their home; others simply could not afford to support themselves when their income was gone. The onset of impairment and disability was an important precipitant of homelessness, both because of the consequent loss of employment and income, and because family support was not forthcoming. Discussion The insecurities experienced by older people living in low- and middle-income countries with limited pension and social welfare provision are well recognized. However, this is to our knowledge the first systematic study of indigent older people from Latin America, and one of the first such studies from any developing country. …
