WA leads the country in population growth
Results from last year's census have shown Western Australia's population has surpassed 2 million people for the first time.
The state's population grew by 14 per cent since 2006, to almost 2, 240,000 people.
That has led to a 76 per cent increase in the price of rental properties to $300 per week.
The national average is 285-dollars a week.
Monthly mortgage repayments also rose from $1,200 to almost $2,000.
The Indigenous population in WA increased by 19 per cent to almost 70,000 people in 2011.
However, the Australian Bureau of Statistics says that may also reflect better surveying of Indigenous people and more people identifying themselves as Indigenous, compared to previous data collections.
The data also reveals the East Pilbara has largest proportionate population growth in Australia.
The region's population has increased by 82 per cent since the last census was conducted in 2006.
The data reveals the East Pilbara's population in 2011 was almost 12,000 people.
Five years ago, that number was just over 6,500.
Census results are used to determine the allocation of government funding and planning for services and infrastructure.
