Answer:
The main components of population change are births, deaths, and migration. “Natural increase” is defined as the difference between live births and deaths. “Net migration” is defined as the difference between the number of people moving into an area and the number of people moving out. For OFM’s annual population estimates, it is more permanent movement that is of particular interest (i.e., not seasonal or temporary). Because it is difficult to measure actual migration, demographers often estimate migration as a residual value, by calculating the difference between total population change and natural increase.
