Why is the social effect of a falling death rate not limited only to population growth?

Answer and explanation

Correct answer: Because age structure and the dependent population can also change

Answer: A. When the death rate falls, more people survive to older ages and average life expectancy may rise. This changes the age composition of the population, not merely its total number. The share of children, working-age people and older people can affect family responsibilities, the dependency burden, healthcare needs, pensions, education and the supply of workers. A is correct because a demographic change can produce several social consequences. B is wrong because death rates strongly affect families and society. C is meaningless and does not describe any demographic effect. D is wrong because a falling death rate can increase population size unless it is balanced by low births, high out-migration or other factors. The exact effect depends on the whole age structure and other population processes. Memory cue: fewer deaths change both the number of people and the composition of people.
