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 consistently negative and the principal factor adding population changed from B-D in the first period to NIM in the latest two periods.

The second chart shows the same data but with an adjustment to reflect births to immigrants shifted to NIM. In it, NIM rose from being a bare majority of population increase in the unadjusted data to a large majority in the adjusted data; becoming nearly the sole factor adding population in the most recent period.
