Sources of Population Change

The primary sources of population change are:

Natural Change [Births minus Deaths or B-D];
Net Domestic Migration [NDM - movement between states]; and
Net International Migration [NIM - movement into and out of the country].
There is also a residual "other" amount that isn't placed in one of those three categories.

The first chart below shows the three population change factors for three periods adjusted for annual average amounts. Domestic migration (NDM) was the primary source of population increase in the first and second periods, and that was due to B-D in the most recent period.

The second chart shows the same data but with an adjustment to reflect births to immigrants shifted to NIM. In it, the same relative roles of the three factors in adding population continued.
