Population bookkeeping over a stated interval adds births and immigration and subtracts deaths and emigration. It does not by itself predict future rates or carrying capacity. The fictional records here include every change in the model.

Worked example

Start 100; births 12; immigrants 5; deaths 7; emigrants 3. End = 100 + 12 + 5 - 7 - 3 = 107.
