In 2005 when Wagga Wagga region of Riverina projected a population of 58,055 ranking 29th in the list of populated cities in Australia (Wagga Wagga 2007), the Perth region ranked 4th with a population of 1,477,800 and a population density of 274.4 per sq. km in the same year (Perth 2007). According to the Australian Bureau of Statistics the Perth metropolitan area alone accounted for around 73% of Western Australia's population (Department of Local Government 2005).
In Perth people over the age of 65+ were found to be the fastest growing age group in 1996-2001 (Department of Local Government 2005). Considerable growth was also observed in the 0-14 year age group during the same inter-census period (Department of Local Government 2005). The picture was just a bit different in the Riverina region where a steady rise in the number of people in the age group of 30+ mostly paved the way for growth in the region (Riverina Regional Development Board n.d.a). The fall in the population of the younger age groups mainly below 30 was overcome to a certain extent by the consistent rise in the older demographics (Riverina Regional Development Board n.d.a).
