From June 2006 to June 2007, Western Australia had the highest growth in the nation, which was an increase of 46,800 persons (2%) from June 2006 and 307,700 persons (17%) from June 1997. In percentage terms, Western Australia's population growth of 17% between June 1997 and June 2007 was higher than the national average of 13% and was the second highest among the states and territories behind Queensland with 23%.
In June 2007, the median age (the age at which half the population is older and half is younger) of the Western Australian population was 36.4 years. This is slightly younger than the national median age of 36.8 years. The median age of the Western Australian population increased from 33.5 years in 1997.
The ratio of males to females aged 0-64 years increased slightly between 1997 and 2007 (103.8 and 104.7 males per 100 females respectively). However, for those aged 65 years and over, the ratio increased from 79.7 to 85.7 males per 100 females over the same ten year period. In 2006, life expectancy at birth was 83.8 years for females and 79.1 years for males in Western Australia. Between 1997 and 2006, the difference in life expectancy between males and females fell from 5.9 to 4.7 years.
