Africa’s population will double by 2050
2050年 , 非洲人口将翻倍
But the education of more African girls means it might peak sooner than most people expect
但是受教育的非洲女童数量增长意味着人口峰值将比人们预料地更早到来
BY 2050, NIGERIA is forecast to have 400m people, meaning it will overtake the United States as the world’s third-most-populous country. The starkness of this fact (its population is currently about 200m) illustrates the degree to which demography will shape Africa’s future. Nigeria’s growth is part of an extraordinary population surge across the continent, but there is controversy about whether it will continue or can be reined in. The answer to that question has serious economic and political implications.
到2050年 , 据估计尼日利亚人口将达到4亿之多 , 这也就意味着该国将赶超美国而成为世界上第三人口大国 。 这一严酷的事实(尼日利亚目前大约有2亿人口)阐释了非洲人口与其未来的关系 。 尼日利亚的人口增长相对于整个非洲大陆的惊人人口数量而言只是冰山一角 , 但是 , 其人口究竟会继续增长还是得到有效遏制 , 各方对此争论不休 。 这一问题的答案会对经济和政治产生重大影响 。
Sub-Saharan Africa’s population is growing at 2.7% a year, which is more than twice as fast as South Asia (1.2%) and Latin America (0.9%). That means Africa is adding the population of France (or Thailand) every two years. Although Asia’s population is four times bigger, almost two children are born each year in Africa for every three in Asia. Most experts agree that, if it continues at its current growth rate, like Nigeria, Africa’s population will double by 2050. That would be 2.5bn people, meaning more than a quarter of the world’s people would be in Africa. Few question those figures because much of the growth is already baked into what demographers term “population momentum”—that is, Africa has so many women of childbearing age that even if most decided to have fewer babies today, the population would keep expanding.
撒哈拉以南的非洲人口每年以2.7%的速度增长 , 这一增速是南亚(1.2%)和拉丁美洲(0.9%)的两倍多 。 这意味着非洲每两年都在增加法国(或泰国)的人口 。 虽然亚洲的人口是非洲的4倍 , 但是每3个孩子出生在亚洲时就有2个孩子出生在非洲 。 大多数专家都认为如果非洲像尼日利亚一样保持现有的人口增长速度 , 截至2050年底 , 非洲人口数量将翻倍至25亿 , 这也就意味着25%以上的世界人口将生活在非洲大陆上 。 几乎没有人质疑这一数据 , 因为非洲人口增长已经符合人口学家所谓的“人口动力”理论———非洲有大量达到生育年龄的妇女 , 即使大多数非洲妇女选择减少生育数量 , 人口总量仍会继续增长 。
