SGSEP - Rental Affordability Index - 3 Bedroom dwellings for Capital Cities (Polygon) Q1 2011-Q2 2021
收藏资源简介：
This dataset presents the Rental Affordability Index (RAI) for 3 bedroom dwellings. The data uses different income values for each region within the Greater Capital Cities, and spans the quarters Q1 2011 to Q2 2021. The RAI covers all states with available data, the Northern Territory and Western Australia does not form part of this dataset.\n\nNational Shelter, Bendigo Bank, The Brotherhood of St Laurence, and SGS Economics and Planning have released the RentalAffordability Index (RAI) on a biannual basis since 2015. Since 2019, the RAI has been released annually.\n\nIt is generally accepted that if housing costs exceed 30% of a low-income household's gross income, the household is experiencing housing stress (30/40 rule). That is, housing is unaffordable and housing costs consume a disproportionately high amount of household income. The RAI uses the 30 per cent of income rule. Rental affordability is calculated using the following equation, where 'qualifying income' refers to the household income required to pay rent where rent is equal to 30% of income: \n\nRAI = (Median income ∕ Qualifying Income) x 100\n\nIn the RAI, households who are paying 30% of income on rent have a score of 100, indicating that these households are at the critical threshold for housing stress. A score of 100 or less indicates that households would pay more than 30% of income to access a rental dwelling, meaning they are at risk of experiencing housing stress.\n\nFor more information on the Rental Affordability Index please refer to [SGS Economics and Planning](https://www.sgsep.com.au/projects/rental-affordability-index).\n\n The RAI is a price index for housing rental markets. It is a clear and concise indicator of rental affordability relative to household incomes, applied to geographic areas across Australia. \n\n AURIN has spatially enabled the original data using geometries provided by SGS Economics and Planning. Values of 'NA' in the original data have been set to NULL.
本数据集提供了针对三居室住宅的租金负担能力指数（Rental Affordability Index, RAI）。数据覆盖大首都城市区域内各分区的不同收入水平，时间跨度为2011年第一季度至2021年第二季度。该指数涵盖所有有可用数据的澳大利亚州份，但北领地与西澳大利亚州未纳入本数据集。 国家庇护所（National Shelter）、本迪戈银行（Bendigo Bank）、圣劳伦斯兄弟会（The Brotherhood of St Laurence）以及SGS经济与规划公司（SGS Economics and Planning）自2015年起每半年发布一次租金负担能力指数（RAI）；2019年起改为年度发布。 学界普遍认可，若住房支出占低收入家庭总收入的比例超过30%，则该家庭正面临住房压力（即30/40准则）。换言之，住房负担能力不足，住房成本占用了家庭过高比例的可支配收入。本租金负担能力指数采用30%收入占比准则。租金负担能力通过以下公式计算，其中“合格收入”指当租金占收入的30%时，家庭所需支付房租对应的收入水平： RAI = (家庭收入中位数 / 合格收入) × 100 在该指数体系中，房租支出占收入30%的家庭得分为100，表明此类家庭正处于住房压力的临界阈值。若得分低于或等于100，则意味着家庭需支付占收入30%以上的租金才能租住住宅，即面临住房压力风险。 如需了解租金负担能力指数的更多信息，请参阅[SGS经济与规划公司](https://www.sgsep.com.au/projects/rental-affordability-index)发布的相关内容。 租金负担能力指数是住房租赁市场的价格指数，是衡量澳大利亚各地理区域内租金负担能力与家庭收入相对关系的简洁明确指标。 AURIN采用SGS经济与规划公司提供的几何数据对原始数据集完成了空间化处理，原始数据中标记为“NA”的数值已被统一设置为空值（NULL）。
