Urban land use in cities in less economically developed countries (LEDCs) differs from patterns in more economically developed countries (MEDCs) in several ways. LEDC cities typically have industry and informal settlements like shanty towns or favelas located on the edge of cities. Favelas are often found on marginal land because it is the only available space, and they are near industry to provide access to jobs. Conditions in favelas are very poor with lack of services and infrastructure. Rapid urbanization in cities like Mumbai and Rio de Janeiro has led to housing shortages and the growth of favela settlements in undesirable areas.
