The article views the recent fertility dynamics in a number of Tropical African countries for which the necessary data is available. It is shown that in the majority of these countries fertility started to decline in the mid-1970-s – early 1990s. However, in the mid-1990s and early 2000s a mass fertility stall occurred throughout the great part of Tropical Africa. Importantly, in most cases fertility got stalled at very high levels, more than 5 children per woman. A decade-long absence of fertility decline bears serious threats of demographic explosions. We present some ways of avoiding the catastrophic scenarios.
Demographic analysis and clusterization of the crisis monotowns, determined by the Ministry of Industry and Trade of the Russian Federation, on type and components of demographic dynamics is carried out in the article. Proceeding the features of the demographic processes, seven types of monotowns are allocated: the cities with positive demographic dynamics (population growth) are presented in three of them, with negative (population decline) — in the rest four types. Th e demographic projections till 2030 are developed for one “standard” monotown from each type (Cherepovets, Norilsk, Lipetsk, Chapaevsk, Tolyatt i and Novotroitsk)
