Methods Based on the Fifth National Popula- tion Census, the basic features, regional difference, spatial distribution and the influencing factors of the population ageing in Baoji City are analyzed respectively with the methods of data comparison, spatial cluster analysis and grey correlation analysis. Results Up to 2000, the characteristics of the population ageing in Baoji City are quite significant; the age compositions of population vary remark- ably in different regions; the proportion of ageing families in central region of Baoji City is relative high; the median age, the ageing population density, the immigrating population, etc, have great re- lation to the proportion of ageing population.
