Why are birth and death data useful in the National Population Policy?

Answer and explanation

Correct answer: They help understand population change

The direct answer is D: birth and death data help us understand population change. Births add people to a population, while deaths reduce its size. By comparing these figures over time, planners can identify whether the population is growing rapidly, growing slowly or changing in another way. This information helps the government plan schools, hospitals, vaccination, food supply, housing and other services. A is wrong because birth and death records do not measure festivals. B is wrong because weather is studied through atmospheric and climatic observations. C is wrong because crop colour is not a population measure. D is correct because these two vital statistics are basic indicators of natural population change. Memory cue: births add, deaths subtract; together they show natural population change.
