What shows the social character of birth rate in population change?

Correct answer: It can be influenced by family size, marriage age, and education

Correct answer: A. Birth rate is a population measure showing the number of live births in relation to the population during a given period, often expressed per thousand people per year. It is not determined only by biology or physical geography. Social conditions such as the usual age at marriage, education, access to information and health services, ideas about family size, and the status of women can influence when and how many children families have. A is correct because it gives genuine social influences. B is wrong because river flow does not alone decide births. C is too absolute; birth rate and death rate are different measures, but both are parts of population change and may be studied together. D confuses a rate with area. Memory cue: birth rate reflects people’s reproductive behaviour within a social and economic setting.
