NOM AND POPULATION GROWTH
Each change to the inward and outward flow of NOM contributes to changes in the growth, size and structure of Australia's population. The official measure of Australia's population is based on the concept of usual residence. As such it includes all people, regardless of nationality, citizenship or legal status, who usually live in Australia (for 12 months or more), with the exception of foreign diplomatic personnel and their families.
Australia's population increases each year as a result of both natural increase (births minus deaths) and NOM (NOM arrivals minus NOM departures). In 2009-10, preliminary NOM estimates added a net of 215,600 persons to Australia's population. This represents 57% of Australia's total population growth for the year (377,100 persons). The remaining 43% was due to natural increase (the number of births minus the number of deaths) with 161,500 persons.
Table 3.3 shows the components of population change over the previous 20 years and the impact NOM has had each year on Australia's population growth. During the majority of this time period, the contribution of NOM to population growth was less than half, whereas in the last four years it has been the major contributor, adding 62%, 65%, 66% and 57% respectively to Australia's total population growth for each year. This increase is partly due to improvements in methodology which better measures the actual true travel behaviour of migrants but also reflects the recent increases of temporary migrants arriving in Australia (see figure 3.13).

(b) Prior to 2006-07, differences between growth and sum of components are due to intercensal discrepancy. |
(c) Estimates for 2009-10 are preliminary - see paragraphs 9-10 of the Explanatory Notes. |
Australia's total population growth rate for 2009-10 was 1.7% with NOM contributing 1.0% to this growth (see figure 3.4). The peaks and troughs in Australia's annual population growth are clearly driven by NOM. Over time, however, the long-term trend shows that NOM has had an increasing contribution to Australia's population growth.
