NET REGIONAL MIGRATION
Net regional migration is the net gain or loss of population through the movement of people from one location to another location within Australia. For the first time, the Australian Bureau of Statistics has prepared a series of annual experimental estimates of regional internal migration. This was based on the 2011 edition of the Australian Standard Geographical Classification (ASGC). The following provides a brief analysis at three substate geographic levels: the Statistical Local Area (SLA), the Statistical Subdivision (SSD) and the Statistical Division (SD). For further information about the methodology used and the ASGC refer to Explanatory Notes 59 to 61.
Statistical Local Area
Just over two million people moved between Statistical Local Areas during 2010-11. This was 1.6% lower than the number of moves estimated in 2009-10 (2.04 million). Around 2.18 million people moved between SLAs in 2008-09, which was the highest number of inter-SLA moves for any year from 2006-07 to 2010-11.
The three SLAs with the highest gains in 2010-11 were all in the Melbourne metropolitan area: Whittlesea (C) - North (4,600 persons), Wyndham (C) - South (4,000 persons), and Casey (C) - Cranbourne (2,800 persons) in Melbourne's north, west and south-east respectively.
Canterbury (C) in Sydney (-2,600 persons), and Gr. Dandenong (C) - Dandenong (-2,000 persons) and Brimbank (C) - Keilor (-1,700 persons) in Melbourne were the three SLAs with the highest net internal migration losses in 2010-11.
At the Statistical Subdivision level, Melton-Wyndham in Melbourne's western suburbs had the highest positive net internal migration estimate in 2010-11 (9,600 persons). Most arrivals into Melton-Wyndham came from the neighbouring SSD of Western Melbourne (9,200 persons), which was well ahead of the next highest source SSDs, Inner Melbourne (1,700 persons) and Hume City (900 persons).
Eastern Middle Melbourne (-5,700 persons) had the highest net outflow of all SSDs in the country in 2010-11. Eastern Outer Melbourne received the most departures from Eastern Middle Melbourne (4,500 persons), followed by Southern Melbourne (2,800 persons) and Booroondara City (2,600 persons) SSDs.
Central Northern Sydney was the SSD with the highest number of net internal migrants aged 0-14 years in 2010-11 (1,700 persons), while Inner Sydney SSD lost the most 0-14 year olds (-2,000 persons).
Melton-Wyndham SSD gained a net 5,700 people aged 25-44 years from other parts of Australia in 2010-11, which was the highest net gain for any SSD in the country. The SSD of Inner Melbourne had the biggest loss of internal migrants aged 25-44, with 3,100 more departures than arrivals in 2010-11, the net outflow of females (-2,000 persons) much higher than males (-1,100 persons).
In terms of people aged 85 and over, Inner Melbourne (200 persons), Eastern Adelaide (70 persons) and Eastern Outer Melbourne (60 persons) were the SSDs with the biggest net internal migration gains in 2010-11. Western Adelaide (-100 persons), Canterbury-Bankstown (-90 persons) in Sydney, and Southern Melbourne (-80 persons) were the SSDs with the highest net outflows of people aged 85 and over in 2010-11.
Perth was the Statistical Division with the highest net internal migration gain of 15-24 year olds in 2010-11 (2,500 persons), with the figure for males (1,500 persons) around 50% higher than for females (1,000 persons). South-Eastern in NSW, which surrounds the Australian Capital Territory, had the highest net outflow of people aged 15-24 to other SDs (-1,100 persons).
