ABS - Socio-Economic Indexes for Areas (SEIFA) (CD) 2001

This data is Census Collection Districts (CD) based Socio-Economic Indexes for Areas (SEIFA) data based on the 2001 census. The data follows the 2001 Australian Standard Geographical Classification (ASGC) boundaries.\n\nThe Australian Bureau of Statistics (ABS) has developed indexes to allow ranking of regions/areas, providing a method of determining the level of social and economic wellbeing in that region. There are four indexes included in the SEIFA 2001 product. Each index summarises a different aspect of the socio-economic conditions in an area. The indexes have been obtained by a technique called principal components analysis. This technique summarises the information from a variety of social and economic variables, calculating weights that will give the best summary for the underlying variables. For the SEIFA indexes, each index uses a different set of underlying variables.\n\nThe four indexes are:\nIndex of Disadvantage (IRSD) - focuses on low-income earners, relatively lower educational attainment, high unemployment and variables reflecting disadvantage. \nIndex of Advantage/Disadvantage (IRSAD) - A new index, and is a continuum of advantage to disadvantage. Low values indicate areas of disadvantage; and high values indicate areas of advantage.\nIndex of Economic Resources (IER) - This index includes variables that are associated with economic resources. Variables include rent paid, income by family type, mortgage payments, and rental properties.\nIndex of Education and Occupation (IEO) - This index includes all education and occupation variables only.\nAll the indexes (including the Index of Relative Socio-Economic Disadvantage) have been constructed so that relatively disadvantaged areas (e.g. areas with many low income earners) have low index values.\n\nThis data is ABS data (catalogue number: 2033.0.55.001) used with permission from the Australian Bureau of Statistics. \n\nFor more information on this data please visit the [Australian Bureau of Statistics](http://www.abs.gov.au/AUSSTATS/abs@.nsf/allprimarymainfeatures/C53F24374E92E8D3CA2573F0000DA0BE?opendocument).Please note: \n\n * AURIN has spatially enabled the original data following the [2001 ASGC](https://data.gov.au/dataset/ds-dga-0b939a62-e53e-4616-add5-77f909b58ddd/details?q=).\n
