Two countries have zero total growth, but one has births and deaths near 30 per thousand while the other has both near 8 per thousand. What difference is likely?

Answer and explanation

Correct answer: The first may have higher demographic turnover and a relatively younger age structure

Zero total growth means that additions to the population are balanced by losses, but it does not mean that birth and death rates must be equally high or that the age structure must match. A country with births and deaths near 30 per thousand has much more demographic turnover: many people are born and many die each year. A country with both rates near 8 per thousand has much less turnover.

The first country may have a relatively young population because high birth rates continually add children, even though mortality is also high. The second may have an older or more stable age structure. Thus option A is the valid possibility. Option B is too definite, while C and D do not follow from the given rates.
