基于隶属函数模型分民族人口老龄化的综合判别

The Aging Comprehensive Definition of Ethnic Minorities Based on the Subordinate Function

人口年龄类型的划分本身为一种模糊的划分,可认为其对应了一个模糊集合.本文以联合国人口年龄类型划分标准中的四个指标为基准,构建了一个综合界定人口年龄类型的隶属函数模型.基于第五、第六次人口普查资料,本文应用构建的综合界定人口年龄类型的隶属函数模型,按人口规模分类研究十年间我国各民族的年龄类型及老龄化程度的变化情况.

The type of population age division is a relatively vague concept, it can be considered to correspond to a fuzzy set. In this paper, we construct a subordinate function to define the type of population age model based on four indications of the United Nations. According to the fifth and the sixth census data of the country, we apply the subordinate function model to analyze the age type and aging degree of ethnic minorities in China by population size classification in ten years.
