[Demographic dynamics of urban growth in Mexico: 1940-1980].

"In this article, the author analyzes the relationship between growth rates and the sizes of cities [in Mexico] to determine what kind of cities are the most dynamic ones in terms of their demographic growth during the 1940-1980 period. [His findings contradict] the widespread belief that in Mexico, as of 1970, there has been a process of 'metropolitanization' and of 'growth of intermediate cities'." He proposes changes to current population policy, which attempts to control urban growth through regulation. (SUMMARY IN ENG)

Population turnaround in the Canadian inner city: contextual factors and social consequences.

"The paper begins with a brief review of the theoretical arguments and empirical evidence that might be used to explain the emergence, sources and spatial variations of inner-city repopulation. The discussion then examines the various forms of property development that underlie the process of repopulation and the possible origins and potential impacts of each form. Examples are introduced to illustrate the trends and relationships involved, drawing on selective references from North American and European cities, but with special emphasis on Canadian cities and the recent Toronto experience. The paper concludes with a brief assessment of the significance of these processes for understanding the changing residential functions and social environments of the inner city."

Africa: rapid population increase retards development.

The Organization of African Unity (OAU), the African Development Bank (ADB) and the UN Economic Commission for Africa (ECA) have criticized African governments for not taking the problem of unchecked population growth seriously enough. "Until recently most African governments did not view rapid population growth as a matter for concern," said the OAU assistant secretary-general for political affairs, Machivenyika Mapuranga, at a seminar on 'population and development'. The OAU estimates that an annual average population increase of 3.1% far outstrips Africa's economic growth, which in 1992 was less than 1%. Mapuranga acknowledged that cutting the population increase is an uphill struggle, especially among rural communities. African agriculture is largely labor intensive, sustained by smallholders, which encourages farmers to have more children. Like other wage earners, African farmers look to support from their family when they grow old and, for that reason, the number of children also counts. But with agricultural production growing at an average annual rate of 2.5%, self-sufficiency in food remains an elusive goal. Cities in sub-Saharan Africa are growing much faster than the overall rate of population increase of 3.1% per year. Between 1980 and 1988 the region's urban population increased at the rate of 6.9% a year. Urban areas now account for nearly 30% of the sub-Saharan Africa population, currently put at 680 million. By 2025, approximately 700 million people are expected to live in urban areas. Despite migration to towns, the rural population is expected to rise more than 68%, reaching over 590 million.
