Answers
Answer:

Demographic structure describes the age distribution of a population and thereby is also called population age structure. It is usually measured by the total dependency ratio, which is the ratio of the total number of the dependent population, aged below 15 and above 65 years, to that of the working-age population.
occupational structure This refers to the aggregate distribution of occupations in society, classified according to skill level, economic function, or social status. ... Such classifications are also used as a basis for the empirical analysis of economic and social class.
