80年代以来我国少数民族出生人口性别比与生育水平变化的历史回顾

An Historical Review on the Sex Ratio at Birth and the Fertility Level Changes of Chinese Minorities Since 1980s

本文以“四普”、“五普”数据为基础,采用人口间接估计技术对20世纪80年代以来我国少数民族人口的生育水平和出生人口性别比变化的历史过程进行回顾,探讨生育水平下降过程中,出生人口性别比的变化趋势,并以蒙古族、回族和维吾尔族为例进行对比分析,结果表明当生育水平下降到较低水平时与出生人口性别比之间有明显的相关关系。

Based on the data of the 4th＇ and 5＇h national census, this paper reviews the changing process of fertility level and birth sex ratio of Chinese Minorities from 1980 to 2000 by indirect estimation, explores the trend of birth sex ratio during the fertility level declines. Taking Moguls, Hui and Unger as examples to explore the relationship, the result indicated the sex ratio at birth is highly correlated to fertility when the fertility level is getting into lower level.
