Question

what is age composition?

Answer 1

Age Composition, in populationstudies, the proportionate numbers of persons in successive age categories in a given population. Age distributions differ among countries mainly because of differences in the levels and trends offertility. A population with persistently high fertility, for instance, has a large proportion of children and a small proportion of aged persons. A population, such as that of France, in which fertility has been low for a long time, has a smaller proportion of children and a larger proportion of aged persons. Changes in fertility have an immediate effect on numbers of children, but many years must pass before the change affects the numbers above childhood. Thus, a population that has experienced a recent decline in fertility tends to have relatively small numbers both of children and of aged persons and a large proportion of adults in the middle ages.

⭐⭐<==================>⭐⭐


✯AGE COMPOSITION: the population of a country compromises three broad groups :-
people aged below 15 years,people aged between 15 years and 65 years and people aged above 65 years.

►The relatively advanced countries have higher proportions of people aged above 15 years in the population. this is because better living conditions and medical facilities have resulted in a higher life expectancy in these countries.
