《科学警报》(Science
Alert)评出欧洲、亚洲和世界其他国家由于出生率下降和老年人比例增加而受到慢性人口炸弹威胁的国家,其中包括美国、西班牙、意大利、韩国,以及日本和中国。
人口慢性定时炸弹是指劳动力比例减小。为了避免这种情况出现,每个妇女必须生育2.2个孩子,但许多发达国家的生育率已经低于2个。出生率降低的结果可能会促使放宽劳动移民限制。但是,如果大量公民去其他国家工作的话,这些措施也无法完全阻止这场危机。
日本的出生率为1.44,韩国为1.26。
中国现在允许每个家庭生两个孩子,但即使这样,到2030年,四分之一的人口将达到60岁(2010年,老年人仅占人口的大约13%)。
新加坡的出生率最低(0.83),但当局计划通过吸引移民来缓和人口炸弹威胁。
