The aim of this document is to describe the socio-demographic, environmental and health-related profile of the population in the Frankston - Mornington Peninsula region, an area south-east of Melbourne, Australia. This population profile serves as an important information source for understanding the context for the National Centre for Healthy Ageing (NCHA) Data Platform. It is also a guide to the types of demographic and spatial data that are available, for potential linkage with electronic health records (EHR) data held within the Healthy Ageing Data Platform and provides context for researchers using data from the Data Platform.
