The interaction of fertility, mortality and migration leads to a consideration of population growth 1. It is convenient to regard population decline 2 as negative growth 3. A distinction may be drawn between a closed population 4 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 population 5 in which there may be migration. The growth of an open population consists of the balance of migration 6 or net migration 6 and natural increase 7, which is the excess of births over deaths 8, sometimes called the balance of births and deaths 8.
