The spatial distribution of heal related vulnerability in the greater Sydney metropolitan region suggests that areas of higher risk are concentrated in the suburbs surrounding the city, extending along the northern coastal suburbs and inland through to western Sydney. Advancing age is the best predictor of heat related risk in the Sydney area. This corresponds to areas with larger proportions of older residents.
Emergency admissions to hospital were used to measure heat related health outcomes in Sydney between 1/1/2000 and 30/6/2010. The threshold temperature used to define hot days in Sydney was a mean Temperature of 31°C. The highest incident rate for emergency hospital admissions was predominantly in the outer western suburbs.
