联合国人口基金会（UN Population Fund）指出，至10月31日，全球人口即将创下历史性里程碑，届时全世界将有70亿人共享地球资源。
联合国人口基金会在全球人口满70亿仪式前夕发布的报告中警告，人口压力对减少贫穷及环境保护带来极大挑战。
人口基金会警告，若出生率略高于预期，全球人口可能在2100年之前飙破150亿人。
联合国人口基金会执行主任欧索提梅辛（Babatunde Osotimehin）表示，人口突破70亿的确是个警讯，提醒相关单位做出行动，特别要注意少女教育和赋予女性控制生育数量的权利。
美国时代杂志（Time）探讨这个人类所面临最急迫的问题，列举出全球大最多的10大城市。以下是这些城市的排行以及目前的人口数量：
1.东京：人口3250万。
2.首尔：人口2060万。
3.墨西哥市：人口2050万。
4.纽约市：人口1980万。
