Sources of Population Change

• 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. Natural change (B-D) was the primary factor in population increase in all periods.

The second chart shows the same data but with an adjustment to reflect births to immigrants shifted to NIM. In it, NIM was the primary factor in population increase in all periods.
