ABS - Socio-Economic Indexes for Areas (SEIFA) - The Index of Relative Socio-Economic Advantage and Disadvantage (LGA) 2006

This data is Local Government Areas (LGA) based Socio-Economic Indexes for Areas (SEIFA) Index of Advantage/Disadvantage (IRSAD) - Is a continuum of advantage to disadvantage. Low values indicate areas of disadvantage; and high values indicate areas of advantage. This data is based on the 2006 census and follows the 2006 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 2006 product. They relate to socio-economic aspects of geographic areas. 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\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/356A4186CCDDC4D1CA257B3B001AC22C?opendocument).Please note: \n\n * AURIN has spatially enabled the original data following the [2006 ASGC](http://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/1216.0Main+Features1Jul%202006?OpenDocument).\n

本数据集为基于地方政府区域（Local Government Areas，LGA）的区域社会经济指数（Socio-Economic Indexes for Areas，SEIFA）优势/劣势指数（Index of Advantage/Disadvantage，IRSAD）——该指数为优势至劣势的连续谱系，指数数值越低代表区域劣势程度越高，数值越高则代表区域优势程度越强。本数据集基于2006年澳大利亚人口普查数据，遵循2006年澳大利亚标准地理分类（Australian Standard Geographical Classification，ASGC）的区域边界。

澳大利亚统计局（Australian Bureau of Statistics，ABS）开发了一系列区域排序指数，用于评估区域社会经济福祉水平。SEIFA 2006数据集共包含四类指数，均围绕地理区域的社会经济特征展开，每类指数分别概括区域社会经济状况的不同维度。上述指数均通过主成分分析（principal components analysis）技术构建：该方法整合多类社会经济变量的信息，通过计算权重以最优方式概括核心变量的特征，且每类SEIFA指数所采用的核心变量集合各不相同。

所有SEIFA指数（包括相对社会经济劣势指数）的构建逻辑均为：劣势程度较高的区域（如低收入群体占比高的区域）对应较低的指数数值。
