This paper uses Vague set theory to make a comparative study in relation to the degree of population aging in different regions of China. By defining the Vague value of the aging vague and contrasting "Matthew effect" function, the paper makes a lateral assessment about the degree of population aging in different regions. This paper innovatively applies Vague set theory, a research tool for uncertainty issues, to study social science issues and reaches a satisfactory result based on the data of statistical yearbook. The research not only provides a new idea and method for the study of aging population, but also opens a new area of application of the vague set.

Key words: demography, population ageing, Vague set, Matthew effect
