In 2004, the NSW Department of Health, in conjunction with the 8 area health services, completed the third year of the New South Wales Population Health Survey, an ongoing survey of the health of people of New South Wales using computer assisted telephone interviewing (CATI). The main aims of the survey are to provide detailed information on the health of the people of New South Wales, and to support the planning, implementation, and evaluation of health services and programs in New South Wales. This 2004 Report on Adult Health from the New South Wales Population Health Survey reports on the health of residents aged 16 years and over.
