In 1985, China’s rate of population increase was nearly 15 per 1,000. Based on prereproductive population, this projection is:

The key idea here is how growth rate is projected from age structure. People in the prereproductive ages (those not yet reproducing) tell you about the potential for future births, but they don’t determine the actual growth rate in a given year. The rate of population increase in a specific year comes from births minus deaths (and migration) happening that year. So using the size of the prereproductive group to claim the annual growth rate for 1985 is not appropriate—it reflects future potential, not the real current increase. That’s why the statement is not correct.
