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 <em>a lot of factors</em>: 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.
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.
