If the birth rate is falling but the total population is still increasing, what is the best conclusion?

Answer and explanation

Correct answer: वृद्धि दर अब भी धनात्मक हो सकती है

Direct answer: B is correct. A falling birth rate means that births are occurring at a lower rate than before; it does not automatically mean that births are fewer than deaths or that the total population is declining. If the birth rate remains higher than the death rate, or if net in-migration adds people, the total population can continue to rise. Thus the population growth rate may still be positive, although it may be slowing. A is wrong because declining birth rate and declining population are not identical. B is correct because positive growth simply means that additions from births and migration are greater than losses from deaths and out-migration. C is wrong because continued growth does not require a zero death rate. D is wrong because migration may contribute to the increase and cannot be dismissed without data. Memory cue: a falling rate can still be a positive rate.
