A Computation and Discussion on MLG of Wang's Clansmen of Huizhou

"平均世代间隔"是一项关于现代人口研究的指标,它不能被用于对古代人口的研究。现笔者通过对徽州汪氏族人平均世代间隔的研究,提出一个用中国宗谱计算该指标的方法。

MLG (Mean Length of Generation) is an index on the population study in modern times, and it can not be used for the study to ancient population. Now the writer advances a way computed this index by the family trees of China by the study to MLG of Wang's clansmen of Huizhou.
