DEMOGRAPHIC INDICATORS

  • Since 2002, when the fertility of the Western Australian population reached an historic low of 1.7 babies per woman, the total fertility rate (TFR) has trended upwards reaching 2.0 babies per woman in 2007. In line with national trends, the recent increase would appear to be the result of higher fertility among women aged 30 years and over.
  • In the 10 years to June 2007, the number of births to mothers aged 35 years and over rose by 72%. These births represented 14% of all births in Western Australia in 1997 but 21% of all births in 2007.
  • Life expectancy has continued to rise for both sexes. In the 10 years to 2007, it rose from 75.7 to 79.2 years for males and from 81.6 to 84.0 years for females.
  • In the past decade the median age at first marriage has steadily increased for both sexes reaching 29.9 years for males and 27.8 years for females in 2008.
  • The crude divorce rate has decreased over the last decade, falling from 2.9 divorces per 1,000 of the estimated resident population in 1998 to 2.2 in 2008.
  • Over the same period, the crude death rate has also decreased from 6.0 to 5.8 deaths per 1,000 of the population.
