In 2005, the proportion of the population in the 20–24, 25–29 and 30–34 year age groups was larger in the Sydney Statistical Division (SD) than for those resident in the balance of the state. Within the Sydney SD males and females aged 25–29 comprised 7.7% and 7.5% of the population respectively, compared with 5.5% and 5.2% for those resident outside of Sydney. In contrast, people over 65 years of age comprised a greater proportion of the population in the balance of NSW than for those resident in the Sydney SD.
POPULATION, SYDNEY SD AND BALANCE OF NSW, By age and sex—30 June 2005
The median age of the NSW population at 30 June 2005 was 36.8 years (36.1 years for males and 37.6 years for females). This was an increase of 1.3 years for males and 1.4 years for females since 2000, again indicating the ageing of the population.
The population of the Sydney SD had a median age of 35.6 years. Three of Sydney's 43 LGAs had median ages over 40.0 years. These were Ku-ring-gai (A) (41.0 years), Gosford (C) (40.4 years) and Pittwater (40.1 years). The lowest median ages were in the west and south-west metropolitan LGAs of Campbelltown (C) (31.9 years), Blacktown (C) (32.2 years), Penrith (C) (32.3 years), Liverpool (C) (32.3 years) and Camden (A) (32.5 years).
In the balance of NSW the highest median age was in the Mid-North Coast SD (42.9 years), while the Murrumbidgee SD (36.0 years) had the lowest median age. In contrast to Sydney, half of the LGAs in the balance of NSW had median ages at or over 40.0 years. The highest medians were located in the coastal region LGAs of Great Lakes (A) (49.1 years), Eurobodalla (A) (46.9 years), Gloucester (A) (45.4 years), Nambucca (A) (45.1 years) and Hastings (A) (45.1 years). The lowest median ages outside of Sydney were in the north west LGAs of Bourke (A) (31.4 years) and Brewarrina (A) (31.9 years) followed by the regional centres of Armidale Dumaresq (A) (33.1 years) and Wagga Wagga (C) (33.5 years).
For NSW in 2005, there were 99.0 males for every 100 females. The 0–4 year age specific sex ratio was 106.1 males per 100 females. Age specific ratios then declined to 101.8 at 25–29 years before stabilising at around 100.0 until the 60–64 year age group. The ratio declined for people in age groups over 65–69 years towards its lowest level of 47.6 for people aged 85 years and over.
For LGAs in the Sydney SD, the highest sex ratios were in Sydney (C) (116.3 males per 100 females) and Auburn (A) (109.5). The harbour-side LGAs of Woollahra (A) (88.2 males per 100 females) and Mosman (A) (89.6) had the lowest sex ratios. Within the remainder of the state, the LGAs with the highest sex ratios were Walgett (A) (124.8 males per 100 females) and Central Darling (A) (124.2). The LGAs of Armidale Dumaresq (A) (93.6 males per 100 females) and Hastings (A) (93.8) had the lowest ratios in non-metropolitan NSW.

WORKING AGE POPULATION – AGED 15–64 YEARS
Over two-thirds of the NSW population (66.9% or 4.53 million people) were of working age (15–64 years) at 30 June 2005, an increase of 39,300 people since June 2004.

All but eight of Sydney's 43 LGAs had proportions of working age residents at or above that of the state. Four inner city LGAs – Sydney (C) (82.1%), North Sydney (A) (78.2%), Leichhardt (A) (77.1%) and Marrickville (A) (75.2%) – recorded over three-quarters of their population in this age group.
