Baulkham Hills Castle Hill

Castle Hill and Baulkham Hills are neighbouring residential areas with large populations and high shares of university-qualified adults. Castle Hill is a more mobile and slightly younger hub, with 46.4% of people moving in during the last five years and a typical resident aged 37. In contrast, Baulkham Hills has a more settled and older population, with a typical age of 40 and a higher share of people aged 65 and over (17.3%).

Both areas have similar proportions of people who have served in the Defence Force, which sits right at the national figure of 1.5%.
