dynamics of growth of major cities
Trends in the growth of large cities
at the present stage.
Currently there are over 130 large and major cities with a total demographic potential of about 87 million people. In the 23 cities with populations of 1 million or more in 1986, lived 42 million people in 33 cities with a population of 500 thousand to 1 million people - 22 million people in 76 cities with a population of 250 to 500 thousand people - 23 million people.
The growth of cities and major towns, the development of their national economic potential for a long period are, as noted, based on extensive factors, demanding involvement in the major cities of large migration flows. Maintaining economic growth was caused mainly a continuation of increasing concentrations of primary production in large and large cities. Its overall level in this country in recent years was higher than in developed capitalist countries, reinforced by centripetal tendencies in the formation of resettlement.
One of the constraints of extensive growth of large and major cities is a sharp narrowing of the demographic base of the replenishment of their workforce (particularly acute in relation to the slow growth of productivity) of labor associated with a decrease in natural population growth and a reduction in the absolute number of rural population. In some areas of the country have a situation where not only the migration to the cities, but insufficient growth of the population can no longer support the functioning of the established settlement.
Despite the fact that the rural population in the country still significantly (in recent years has slowed the pace of decline) significantly transformed its structure. Drastically reduced the number of residents under 40 years while the population over age 40 increased by 1 / 3 compared with 1959
