Question

For which of the following populations is total population change equal to the rate of natural increase?

Answer 1

Answer:

Correct answer is E. Never is total population change equal to the rate of natural increase, because total population change includes migration.

Explanation:

Demography is the study of population statistics and its variations. Total population change is how the number of people living in a specific place changed over a specific period of time. But this includes a lot of factors: sex ratios in that specific population, migration rates AND the rate of natural increase, which only takes into account the life births and deaths occurring in that specific area.  

Answer 2

Answer:

D) World

Explanation:

The rate of population growth is the rate of natural increase combined with the effects of migration. Thus a high rate of natural increase can be offset by a large net out-migration, and a low rate of natural increase can be countered by a high level of net in-migration. Generally speaking, however, these migration effects on population growth rates are far smaller than the effects of changes in fertility and mortality.
