Which source is used to know population growth?

Answer and explanation

Correct answer: Census data

Direct answer: A, census data. A census is an organised counting and description of the population carried out at a particular time. When population figures from two different census years are compared, we can find whether the population has increased, decreased, or remained nearly unchanged. The comparison can also show changes in population size and growth rate. B is wrong because a song does not provide measured population figures. C is wrong because a drawing book is not a demographic record. D is wrong because a tourism poster may advertise places but does not provide systematic population data. Memory cue: census counts people; comparing census counts helps measure population growth.
