HUD Housing Affordability Data System

The Housing Affordability Data System (HADS) is a set of files derived from the 1985 and later national American Housing Survey (AHS) and the 2002 and later Metro AHS. This system categorizes housing units by affordability and households by income, with respect to the Adjusted Median Income, Fair Market Rent (FMR), and poverty income. It also includes housing cost burden for owner and renter households. These files have been the basis for the worst case needs tables since 2001. The data files are available for public use, since they were derived from AHS public use files and the published income limits and FMRs. We are providing these files give the community of housing analysts the opportunity to use a consistent set of affordability measures.<br><br>This data set appears to not be upated after 2013

住房负担能力数据系统（Housing Affordability Data System, HADS）是由1985年及后续年份的全美住房调查（American Housing Survey, AHS）、以及2002年及后续年份的大都市住房调查（Metro AHS）衍生而来的数据集文件集合。该系统以调整后中位数收入、公平市场租金（Fair Market Rent, FMR）与贫困线收入为参照，将住房单元按负担能力分类、住户按收入水平划分，同时涵盖自有住房住户与租赁住房住户的住房成本负担情况。自2001年起，这些文件便成为编制最差情形需求表的核心依据。由于本数据集衍生自AHS公开使用文件及已发布的收入限额与公平市场租金数据，因此面向公众开放获取。我们推出此类数据文件，旨在为住房分析从业者群体提供一套统一的负担能力衡量标准以供使用。<br><br>该数据集似乎在2013年之后未再进行更新。
