Ripidly rising birth rate AND FALLING DEATH rate is OPTIONs (A) Life Expectancy (B) overpopulation (C) Polution (D) Pollution

Answer 1

Answer:

Hence, a relatively large number of couples each having one or two children can still produce a large excess of births. This phenomenon is known as population momentum. In the United States, birth rates are higher than death rates at present, partly due to the relatively young age structure of the U.S. population.
