非洲的人口动态与分布

非洲的人口动态长期以来具有高出生率、高死亡率的特点，20世纪90年代以后，非洲的人口动态由高出生高死亡模式向高出生中死亡模式转变．死亡率的持续下降在很大程度上是由于数种过去危害最严重的急性传染病基本上得到有效控制的结果。正是死亡率的下降和持续的高出生率导致非洲人口迅速增长。在非洲人口增长的过程中．人口分布是极不平衡的。非洲人口分布的变化与经济因素的人口定期迁移是密切相关的，大致可分为三种情况．这种独特的迁移模式均与经济活动和生产方式直接相关。

Africa's population dynamics and distribution

Population dynamics in Africa a long time with high fertility, high mortality rates characteristic of the 20th century, after the 90＇s, Africa＇s population dynamics by high-born high-death model to the high birth death model, mortality continued to decline in large extent due to a number of past crimes against the most serious acute infectious diseases had been largely the result of effective control. It is the decline in mortality rates and continuing high birth rate leading to rapid population growth in Africa. Population growth in Africa, the population distribution is extremely uneven. Changes in population distribution in Africa and economic factors of the population regularly migration are closely related, can be broadly divided into three cases, this unique migration patterns are related to economic activities and modes of production are directly related.
