文本：Fair enough, but in the longer term, the figures aren't going to be dominated by the likes of you and me. It's the birth of new people that will have the largest effect on future statistics. And here's where it gets interesting. For a long time statisticians have observed something which they call the "demographic transition". 

 

译文： 很好，但从更长远的角度来看，未来的数据并不是由我们这些已经出生的人决定的，而是由新生儿决定的。这一点十分有意思。长期之来，统计学家一直在研究“人口过渡”这一概念。
