BIRTHS AS A COMPONENT OF POPULATION CHANGE
Births are an important component of population change. In 2009, there were roughly twice as many births as deaths. Although the number of births per woman is low, there are enough women currently in childbearing ages to retain a relatively high total number of births. Conversely, there are relatively few people at older ages, resulting in a relatively low number of deaths per year. As the population ages, the difference between numbers of births and deaths will decrease. Based on Series B of the most recent ABS population projections (Population Projections, Australia, 2006 to 2101, cat. no. 3222.0), the number of births is projected to remain higher than the number of deaths throughout the projection period.

| (a) Calendar year. |
| (b) For 2008 and earlier years, births and deaths in this table are based on year of occurrence, for population estimation purposes. For 2009, a combination of data based on quarter of occurrence (for the March and June quarters) and quarter of registration (for the September and December quarters) is used. Numbers of births in this table will therefore differ from data elsewhere in this publication. |
| (c) Population increase will not necessarily equal the sum of natural increase and net overseas migration due to intercensal discrepancy. See Glossary for more information. |
