Description: The Index of Household Advantage and Disadvantage (IHAD) provides a summary measure of relative socio-economic advantage and disadvantage for households, based on the characteristics of dwellings and the people living within them, using 2021 Census data. All in-scope households are ordered from lowest to highest score. A low score indicates relatively greater disadvantage and a lack of advantage in general. A high score indicates a relative lack of disadvantage and greater advantage in general. This dataset presents IHAD data in quartiles. The lowest 25% of households are given a quartile number of 1, the next lowest 25% of households are given a quartile number of 2 and so on, up to the highest 25% of households which are given a quartile number of 4. This means that households are divided into four equal sized groups, depending on their score. In practice these groups won’t each be exactly 25% of households as it depends on the distribution of the IHAD scores. The data is grouped by Statistical Area Level 1 (SA1 2021). SA1s are defined by the Australian Statistical Geography Standard (ASGS) Edition 3. Key Attributes: Field alias Field name Description Statistical Areas Level 1 2021 code SA1_CODE_2021 2021 Statistical Areas Level 1 (SA1) codes from the Australian Statistical Geography Standard (ASGS), Edition 3. SA1s are designed to maximise the geographic detail available for Census of Population and Housing data while maintaining confidentiality. Statistical Areas Level 1 2021 name SA1_NAME_2021 2021 Statistical Areas Level 1 (SA1) names from the Australian Statistical Geography Standard (ASGS), Edition 3. SA1s are designed to maximise the geographic detail available for Census of Population and Housing data while maintaining confidentiality. Area in square kilometres AREA_ALBERS_SQKM The area of a region in square kilometres, based on the Albers equal area conic projection. Uniform Resource Identifier ASGS_LOCI_URI_2021 A uniform resource identifier can be used in web linked applications for data integration. IHAD quartile 1 IHAD_QUARTILE1 Proportion of in-scope dwellings in the SA1 that fall into IHAD quartile 1, indicating relatively greater disadvantage and lack of advantage in general. IHAD quartile 2 IHAD_QUARTILE2 Proportion of in-scope dwellings in the SA1 that fall into IHAD quartile 2. IHAD quartile 3 IHAD_QUARTILE3 Proportion of in-scope dwellings in the SA1 that fall into IHAD quartile 3. IHAD quartile 4 IHAD_QUARTILE4 Proportion of in-scope dwellings in the SA1 that fall into IHAD quartile 4, indicating a relative lack of disadvantage and greater advantage in general. Occupied private dwellings OPD_2021 Dwellings in-scope of the IHAD i.e. classifiable occupied private dwellings. SEIFA IRSAD quartile IRSAD_QUARTILE Index of Relative Socio-economic Advantage and Disadvantage quartile. All SA1s are ordered from lowest to highest score, the lowest 25% of SA1s are given a quartile number of 1, the next lowest 25% of SA1s are given a quartile number of 2 and so on, up to the highest 25% of SA1s which are given a quartile number of 4. This means that SA1s are divided into four equal sized groups, depending on their score. In practice these groups won’t each be exactly 25% of SA1s as it depends on the distribution of SEIFA scores. Usual resident population URP_2021 Population counts in this column are based on place of usual residence as reported on Census Night. These include persons out of scope of the IHAD. Dwellings DWELLING Total dwellings at Census time, including dwellings out of scope of the IHAD e.g. unoccupied private dwellings.
