This report presents a spatial analysis of population density and its correlation with health and socio-economic factors in Australia, using QGIS software. The research investigates the impact of population density on circulatory and digestive diseases, as well as household income levels across different regions. The methodology involves loading and manipulating geospatial data from a geo package within QGIS, creating population density maps, and analyzing spatial patterns. The findings indicate that population density disparities affect health, income, and employment opportunities. Densely populated coastal areas show higher household incomes but also face higher unemployment and digestive health problems, while inland, sparsely populated areas experience more circulatory diseases. The report concludes by emphasizing the need for government initiatives to encourage investment in inland and rural areas to balance population distribution and resource pressure.
