For several thousand years, the world has been experiencing increased urbanization. In 2008, the UN Population Fund announced that the world now has more urban than rural inhabitants(1), and this trend is far from slowing down. It is projected that between 2007 and 2050, the population of the world will increase by 2.5 billion, at which point two thirds of the developing world will reside in urban areas.(2) Approximately 75% of this rapid expansion is expected to be found in smaller cities (500,000 to 1.6 million people), which currently house more than 50% of the world’s urban population.(3) Cities offer many health benefits, including large markets with a reliable food supply, economies of scale, stable public services, and a collection of educated individuals that contribute to enterprise, education, and innovation.(4)
However, while urbanization has helped improve development and health in the long run, it has produced some negative consequences as well. As populations increase at unprecedented rates, communities are overwhelming cities that lack adequate infrastructure and municipal organization to handle the rising challenges. This situation is most problematic in developing countries, where urban slums and other areas with concentrated populations have grown, thereby increasing greenhouse gas emissions. Further, these countries face an elevated risk of disease, while health care systems struggle to catch up and are unable to respond effectively.(6)
Measures of poverty have traditionally been based on income or consumption, and many official measures of poverty, particularly in developing countries, are still centered on these figures. To calculate food consumption, a standard measure is specified, typically in terms of a “basket” of basic nutritional necessities. The estimated monetary income required to purchase the basket then sets the food poverty line. To calculate the overall poverty line, non-food goods and services such as shelter, health care and clothing are added to the food calculations. Additionally, surveys of living standards gauge consumption based on ownership of items such as a bicycle or refrigerator, and include questions about the materials used to construct the home.(7)
Recently, the focus has moved beyond traditional measures and switched to a more multidimensional analysis, as income or consumption alone may produce false notions of poverty. In his Population Bulletin, Mark Montgomery provides a framework for multiple aspects of urban well-being. This consists of the following areas:
Links between dimensions can provide a more comprehensive understanding of poverty. For instance, a household that is not considered poor in terms of one of the above variables may lack in many other vital areas of well-being. This is clear in places such as Indian slums, where many families’ consumption levels place them far above the poverty line, though their houses are so poorly constructed that they could be considered inhospitable.(8)
Urban absolute poverty usually includes interrelated deprivations relating to each of Montgomery’s dimensions. These typically include:(9)
Though cities are growing, most of the poor populations of the world remain in rural areas. Rural areas are home to about 75% of the poor and are still expected to house 60% by 2025. Based on comparison studies, rural populations of Vietnam, India, and Zimbabwe suffered significantly more than urban populations did in categories that included numbers of impoverished residents, child mortality rates, sanitation quality, and levels of education.(10) This suggests that when dealing with averages (and not distinguishing between rich and poor urban groups), there appears to be what is generally considered an “urban advantage.”
On the other hand, averages do not account for major differences between socioeconomic groups within each region, and they do not reflect multidimensional forms of poverty. Large groups of the urban poor live in environments equal to or worse than those of rural villagers, in terms of health. Though rural families may not have the sanitation services, for instance, that many urbanites have, rural communities have lower population densities, helping to limit the spread of disease.(11) Thus, even if there is an “urban advantage” in some aspects of life, there can also be an “urban disadvantage” in other dimensions, creating concepts of “poor” that are not necessarily related to income or consumption. While many differences exist within cities, variety between cities is also important to note. In East Asia, for example, “more than 90 % of the poor live in rural areas,” while Latin America and the Caribbean have more of an urban poor population, with rural families comprising 40% of the poor.(12)
When comparing averages, it is important to remember that city and countryside communities work together and influence each other. Christopher Dye of the World Health Organization (WHO) uses the term “national metabolism” to describe the interaction between cities and rural areas.(13) Studies show that the wealth of cities often directly benefits rural villagers. On the other hand, greater availability of jobs draws people to migrate to cities, where they then suffer from unfamiliar urban poverty. In this way, improvements in rural poverty can aid urban poverty as well.(14)
Several features distinguish urban poverty from poverty in other areas. As Mark Montgomery summarizes in his report, these features include:
“The monetization of urban living; the spatial concentration of the population in environments that are sometimes but not always well-supplied with protective public services; the inescapable economic and social diversity that confronts the urban-dweller in daily life; and the geographic proximity of modern health care institutions that may nevertheless lie beyond the reach of the poor – these and similar factors are far more prominent in urban than in rural settings.”(15)
The urban poor are not a homogenous group; there are three discernible categories of poor urban dwellers, according to Akin L. Mabogunje, Chairman of the Presidential Technical Board of the Federal Mortgage Bank of Nigeria. The first is the “new poor” who have been recently impoverished, and the second is the “borderline poor” who are employed yet unskilled and below the poverty line. The third is the “chronic poor” who have been poor for five or more years and are sometimes impoverished due to the process of migration to cities, rather than from urban poverty itself.(16) Furthermore, children make up a large percentage of the urban poor population. For example, in Bangladesh, the majority of residents are under fifteen years old. Despite child advocacy interventions, many of these children and teenagers are part of the workforce.(17)
A large proportion of cities’ poor residents live in slums. According to studies by WHO and the United Nations Human Settlements Programme (UN-HABITAT), one third of all urban inhabitants reside in slums or informal settlements, and more than 90% of slums exist in cities within developing countries. Typically, the fastest growing cities have the highest concentrations of these settlements. In a recent study comparing regions in the developing world, Sub-Saharan Africa was found to have the highest rate (62%) of urban residents living in slums.(18)
A slum residence is defined by UN-HABITAT as one with “inadequate housing, sanitation, tenure security, and no or few basic services.”(20) This type of housing exists in a variety of forms, “from high-rise tenements to shacks to plastic sheet tents on sidewalks.”(21) These critical challenges that slums face should be the focus of future development strategies, as slums often have the worst conditions and health risks within cities.
