Total growth  (TOTAL growth)


The interaction of fertility and mortality leads to a consideration of population growth1. Itis convenient to regard a population decline2 as negative growth3. A distinction may be drawn between a closed population4 in which there is no migration either inwards or outwards and whose growth depends entirely on the difference between births and deaths, and an open population5 in which there may be migration. The total growth6 of an open population consists of the balance of migration (cf. chapter 8) and natural growth7 or natural increase7 which is the excess of births over deaths8, sometimes called the balance of births and deaths8.
