ESTIMATED RESIDENT POPULATION
The preliminary estimated resident population (ERP) for South Australia was 1,575,700 at 31 December 2006, an increase of 16,100 persons (1.0%) since 31 December 2005. The annual population growth for the year ended 31 December 2005 was 0.9%. The total ERP was rebased on data from the 2006 Census of Population and Housing as of June 2006 and as such would be different from the total of population derived from the table components.
All states and territories recorded population growth over the 12 months ended 31 December 2006. Western Australia recorded the largest growth rate (2.1%) and Tasmania recorded the lowest growth rate (0.6%).
For the 12 months ending 31 December 2006, South Australia recorded a natural increase (i.e. net of births and deaths) of 6,332 persons. Net overseas migration provided a gain of 11,150 persons in the same period while net interstate migration realised a loss of 2,765 persons.
In the December 2006 quarter South Australia recorded a net natural increase of 1,514 persons and a gain in net overseas migration of 2,810 persons. For every quarter since September 1986, with the exception of June 1993 (-217 persons) and June 1994 (-5), there has been a net overseas migration gain in South Australia's ERP. Net interstate migration in the December 2006 quarter resulted in a loss of 1,100 persons from South Australia. Since September 1986, South Australia has only shown a net increase in population from interstate migration in 11 out of the 80 quarters, and 9 of these quarters occurred before March 1992.
Nationally, the preliminary ERP was 20,852,000 at 31 December 2006, an increase of 293,000 persons (1.4%) since 31 December 2005. The population growth rate for the year ended 31 December 2006 (1.4%) was about the same as that recorded for the year ended 31 December 2005 (1.4%). For the year ended 31 December 2006, Australia recorded a natural increase in population of 132,051 persons; net overseas migration resulted in a gain of 147,723 people.
In the December 2006 quarter Australia's population recorded a natural increase of 34,694 persons. The net overseas migration for Australia resulted in a gain of 38,468 persons.
