Потери мегаполиса в контексте миграции (на примере Москвы)
The article analyzes the specifics of urbanization dynamics in Egypt, which is noteworthy for a number of reasons. First, there was a shift from the logistic trend in the 1970s, and the share of urban population stopped growing. The UN data analysis shows that such a shift usually occurs against the background of very serious economic difficulties (and other problems associated with them). However, the urban population proportion stopped growing in Egypt when the country was experiencing a period of exceedingly rapid economic growth. We find labor migration of unprecedented scale to be the main reason which engendered this seemingly paradoxical situation. We further proceed to analyze the UN forecast on the dynamics of the Egyptian urban population proportion up to 2050, which implies a return to the logistic trend and rapid growth of the urban population share, which is fraught with socio-political instability risks. However, we present data proving that the logistic urbanization trajectory is not inevitable for Egypt, and the destabilization risks connected with the rapid increase of urban population share are largely irrelevant to Egypt in the forecasted period.
The article presents research results in respect to the model of evaluation of sustainable development of a megalopolis, fulfilled with the financial support of St.Petersburg municipal government. The informational model presented allows providing for the complex of measures necessary for the systemic increase of sustainability of megalopolis' development.
Regional variation of all features of mortality is quite significant. Being noted for many decades The North-Ost gradient of increased mortality rate continues its trend. In a time despite essential regional variation of mortality the difference in the orientation of its dynamic is not significant at all. An important condition for development of measures to ensure a decrease of mortality rate is information on social and demographic factors.
