Excess of births

Excess of births is the difference of births over deaths.

This is one of the two major key variables affecting population size, the other being net migration. Excess of births is also known as the natural population growth as this reflects population growth when immigration and emigration figures are equal.

Glossary:

  • Excess of births is the difference of live births over deaths.
  • The ‘per 1,000 unit’ is used to account for differences in population, sex distribution, etc. This makes it possible to compare periods with e.g. different populations.
