Analysis of territorial patterns of age population structure at the subnational level in Chile

Abstract

<div><p>From the evidence obtained in the 2017 Chilean population census pyramid for the country scale, the question arises whether the population structure by age is replicated homogeneously at the subnational level or, on the contrary, it presents heterogeneous local characteristics based on age groups. For each of the third-level subnational units (n=346), the standard deviation of the different age classes was compared in relation to the national population pyramid. With these differences, the k-means method was used to identify eight groups of communes, and four demographic indicators were calculated. The results allow to affirm that the population structure by age and sex at the communal level presents heterogeneous characteristics. The analysis of territorial patterns identified groups of the aging population, households with active aging, transition to aging, adult population, men in terminal productive age, men in initial age, households with children under 15 years and households with children over 15 years.</p></div>
