If death rate decreases and birth rate remains the same in an area, what can happen to population growth?

Answer and explanation

Correct answer: Population growth may increase

Correct answer: A. Population growth depends partly on the balance between births and deaths. If the birth rate stays unchanged but the death rate falls, fewer people are being lost through death while births continue at the same level. Therefore, the difference between births and deaths can become larger, causing natural increase and overall population growth to rise. The word “may” is important because migration and other conditions can also affect the total population. B is wrong because a lower death rate cannot make the population zero. C is wrong because death rate and birth rate are separate measures; reducing deaths does not stop births. D is wrong because population processes do not automatically change the physical area of a region. Remember: same births plus fewer deaths generally means faster natural growth.
