demographic trend

Speaking to a pensions conference in Edinburgh, Mr Coughlan explained there were two kinds of longevity risk: the general demographic trend and scheme-specific risk.

在爱丁堡召开的一项养老金会议上，考夫兰解释道，有两种寿命风险：一般的人口统计学趋势，以及各计划具体的风险。

With a population of 1.4bn, part of the issue in China is its scale, says Prof Kohlbacher, although the one-child policy has exaggerated the demographic trend.

科尔巴赫表示，由于拥有14亿人口，中国的部分问题与其规模有关，但独生子女政策又放大了这种人口老龄化趋势。

This could happen either when the favourable demographic trend worsens or urbanisation ends.

当有利的人口统计学趋势恶化，或城市化进程结束时，都可能出现这种局面。

These modifications are necessary aiming at simulating the real system. Then a population model is presented and the demographic trend is forecasted during the next dozens of years.

这部分给出了一个人口模型，并用该模型预测了未来几十年我国的人口结构。
