INTRODUCTION
The cultural and linguistic diversity of Australia's resident population has been reshaped over many years by migration. Successive waves of migrants to, and from, every area of the world have contributed to the ever-changing mosaic of Australia's diverse population. Historically, more people immigrate to, than emigrate from, Australia. At 30 June 2010, data on the estimated resident population of Australia (22.3 million people) revealed that 27% of the population was born overseas (6.0 million people). This continues the historical trend of a large proportion of overseas-born among Australia's population.
