The GMI results are based on Census data from 2001 and 2011 to show changes in the multicultural make-up of urban areas. This has been done by comparing the 43 local councils across the Sydney region, from Wyong and Gosford in the north, west to the Blue Mountains, and south to Wollondilly, Campbelltown, and Sutherland.
The GMI is a weighted index that considers four key factors:
1) Percentage of foreign born population;
2) Total foreign born population;
3) Percentage of population born in non-English speaking countries; and
4) Whether any one ethnic or national group makes up more than 25% of the foreign born population.
