The Progress in Australian Regions–Yearbook is a statistical resource that measures progress in a region against social, economic, environmental and governance indicators. The Yearbook brings together information about Australia's regions from a range of different sources and presents that data in a consistent format over time. This fourth edition updates information from previous editions of the Yearbook and is incorporating newly released data from the 2016 Census where appropriate. Update (July 2018): New Excel files have been added with additional geographic boundaries, where data is available at that scale (Local Government Areas, Statistical Urban Areas, Statistical Areas Level 2, Statistical Areas Level 3). These are additional to the data in the published Yearbook. Note that data for areas with very small populations should be used with caution, as small numbers can be significantly impacted by random adjustment.
