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. All the population increase in each of the three periods is due to either natural change (B-D) or immigration (NIM) as there was a population loss - net outflow - from domestic migration (NDM). Natural change (B-D) was the primary factor in population increase for each of the three periods.

The second chart shows the same data but with an adjustment to reflect births to immigrants shifted to NIM. In it, NIM replaced B-D as the primary factor in population increase.
