Trends in urban and slum indicators across developing world cities, 1990–2003

This paper analyses trends in the living conditions of slum and non-slum populations over the period 1990–2003, using urban and slum indicators from several developing world cities. It explains why where a person lives might condition his/her general health and household vulnerability. The data used are from UN-Habitat's Global Urban Observatory database for 188 cities belonging to 8 different Millennium Development Goals Regions. The study provides evidence of a general improvement in various slum indicators, such as durable structures, access to safe water and access to improved sanitation. However, although there has been a decrease in under-5 mortality at city level, we observe that the same indicator can be up to five times higher for slum than for non-slum groups. We conclude that this evidence supports the importance of slum improvement and highlights this issue as one of the major challenges that a predominantly urbanized world faces.
