ABS Socio-Economic Indexes for Areas (SEIFA 2021) Data - Free

## Australian Bureau of Statistics Socio-Economic Indexes for Areas (SEIFA) Data<br/>(SEIFA 2021 – ABS)

The Socio-Economic Indexes for Areas (SEIFA) are a suite of indexes produced by the Australian Bureau of Statistics (ABS) that rank geographic areas across Australia according to relative socio-economic advantage and disadvantage. SEIFA is derived from Census data and is widely used in government, finance, real estate, infrastructure planning, and social research to provide socio-economic context for analysis and decision-making.

SEIFA 2021 is based on data from the 2021 Census of Population and Housing and reflects the relative socio-economic conditions of people living in different areas at that time. The dataset provides consistent, nationally comparable measures that enable analysis across multiple geographic levels.

The four SEIFA indexes included are:

• Index of Relative Socio-Economic Disadvantage (IRSD)<br/>• Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD)<br/>• Index of Economic Resources (IER)<br/>• Index of Education and Occupation (IEO)

Each index includes scores, ranks, and deciles that allow areas to be compared both within and across geographies. These measures support use cases such as identifying relative disadvantage, assessing investment risk and opportunity, informing service delivery planning, enriching location intelligence platforms, and enhancing socio-economic modelling.

Geographic coverage includes Statistical Areas Level 1 (SA1), Statistical Areas Level 2 (SA2), Statistical Areas Level 3 (SA3), Local Government Areas (LGAs), and Postal Areas (POAs).

Typical use cases include socio-economic profiling, property and location intelligence, credit and risk analysis, public sector reporting, infrastructure planning, and enrichment of analytical and predictive models requiring consistent, Census-derived socio-economic indicators.

澳大利亚统计局（Australian Bureau of Statistics, ABS）区域社会经济指数（Socio-Economic Indexes for Areas, SEIFA）数据集<br/>(2021版SEIFA——澳大利亚统计局出品)<br/><br/>区域社会经济指数（Socio-Economic Indexes for Areas, SEIFA）是澳大利亚统计局（Australian Bureau of Statistics, ABS）编制的一系列指数，用于依据相对社会经济优势与劣势对澳大利亚全国范围内的地理区域进行排序。该指数体系源自人口普查数据，被广泛应用于政府、金融、房地产、基础设施规划及社会研究领域，为分析与决策提供社会经济层面的背景支撑。<br/><br/>2021版SEIFA基于2021年人口与住房普查数据编制，反映了当时澳大利亚不同区域居民的相对社会经济状况。本数据集提供了统一且可在全国范围内比较的衡量指标，支持跨多个地理层级开展分析。<br/><br/>本次数据集包含以下四项SEIFA指数：<br/>• 相对社会经济劣势指数（Index of Relative Socio-Economic Disadvantage, IRSD）<br/>• 相对社会经济优势与劣势指数（Index of Relative Socio-Economic Advantage and Disadvantage, IRSAD）<br/>• 经济资源指数（Index of Economic Resources, IER）<br/>• 教育与职业指数（Index of Education and Occupation, IEO）<br/><br/>每一项指数均包含得分、排名及十分位分组，可实现区域在同一地理层级及跨地理层级间的对比。上述指标可应用于诸多场景，例如识别相对劣势区域、评估投资风险与机遇、为服务交付规划提供参考、丰富位置智能平台的数据维度，以及优化社会经济建模工作。<br/><br/>详见：<br/>[https://www.abs.gov.au/statistics/people/people-and-communities/socio-economic-indexes-areas-seifa-australia/latest-release](https://www.abs.gov.au/statistics/people/people-and-communities/socio-economic-indexes-areas-seifa-australia/latest-release)<br/><br/><p><br/></p><br/>**可用模式：**<br/>SEIFA<br/><br/><p><br/></p><br/>**可用数据表：**<br/>SEIFA.SEIFA_SA1<br/>SEIFA.SEIFA_SA2<br/>SEIFA.SEIFA_SA3<br/>SEIFA.SEIFA_LGA<br/>SEIFA.SEIFA_POA<br/><br/>数据集的地理覆盖范围包括：1级统计区域（Statistical Areas Level 1, SA1）、2级统计区域（Statistical Areas Level 2, SA2）、3级统计区域（Statistical Areas Level 3, SA3）、地方政府区域（Local Government Areas, LGAs）以及邮政区域（Postal Areas, POAs）。<br/><br/>典型应用场景包括：社会经济画像绘制、房地产与位置智能分析、信贷与风险评估、公共部门报告编制、基础设施规划，以及为需要统一普查来源社会经济指标的分析与预测模型补充数据维度。
