我国这几年的人口增长已经很低了，而隔壁日本和韩国更低，甚至人口开始负增长了。随着经济的发展，人口增长减速是很正常的事情。即便是现在我们觉得人口增长速度很快的印度，实际上近些年人口增长率也大大降低了。而更贫穷的非洲地区已经成为地球人口增长最快速的地区。
但是根据联合国的一项统计数据显示，到2084年的时候，地球人类将会迎来一个大拐点。60年后的时候，地球每年的出生人口将会小于死亡人口，整个地球上的人口开始减少。
下面的表格中我们将会统计从1950年到2100年这151年时间里全球人口的变化数据情况：

在2023年，全世界大约有1.32亿名婴儿出生，同时有6200万人死亡，也就是说这一年地球上新增了7000万人口（增长率为0.9%）。
但是到了2100年的时候，全球人口将减少近1300万人，大约相当于玻利维亚目前的人口。
当然，上述情况的出现有一个大前提，那就是未来这60年里世界不会有更大的变革，还会和当前世界的发展类似。
