Migration, population growth, and development

Area of Science:

• Demography
• Urban Studies
• Sociology

Background:

• The developing world's population nearly doubled between 1950 and 1980, leading to significant urbanization and international labor migration.
• Cities in Africa, Asia, and Latin America experienced growth rates more than twice those in North America and Europe.
• Approximately 15 to 20 million workers, primarily from developing nations, were international migrants during this period.

Purpose of the Study:

• To analyze the drivers and patterns of rapid urbanization and international labor migration in developing countries.
• To evaluate the effectiveness of existing government policies aimed at influencing population distribution.
• To identify potential interventions for managing population growth and migration trends.

Main Methods:

• Analysis of population data from 1950 to 1980, focusing on urban growth and international migration.
• Review of government policies and their limited success in controlling population distribution.
• Examination of economic factors as primary drivers of migration decisions.

Main Results:

• Urban populations in developing countries grew from under 300 million in 1950 to about one billion.
• Urban growth was driven by 40% migration and 60% natural increase (births).
• International migration was largely economically motivated, with varied settlement intentions and patterns across regions.

Conclusions:

• Rapid urbanization and international migration present significant social, economic, and political challenges for developing countries.
• Existing policies to influence population distribution have had limited success due to persistent high birth rates and wage differentials.
• Family planning programs offer a viable strategy to reduce birth rates, thereby addressing a key component of urban growth and potential migration.
