Why is census useful in the study of population growth?

Answer and explanation

Correct answer: It gives official population figures for different years

Answer: A, because a census provides official population information for a particular time, and repeated censuses allow comparison across years. By comparing population totals and other recorded characteristics, researchers can study growth, distribution, age structure and related changes. Governments can also use census information for representation, resource allocation and public-service planning. A is correct even though a census may collect more than just total population. B, C and D describe weather, rivers and mountains, which are not the main purpose of a population census. Memory cue: census is an official population count used for comparison and planning.
