Extensions to Estimated Housing Authority Service Areas Methodology

<p><span style='background-color:rgb(255, 255, 255);'><font size='4'>The data provided here denotes the authors’
revised service areas for a subset of 377 Public Housing Authorities (PHAs) for
which HUD <a href='https://hudgis-hud.opendata.arcgis.com/datasets/HUD::estimated-housing-authority-service-areas-1/about' rel='nofollow ugc'><span style='color:#1155CC;'>previously estimated service areas</span></a>. Using HUD
administrative data on the location of Housing Choice Voucher holders, HUD’s
estimated service areas were revised to better capture voucher activity.
Specifically, the authors developed two different tests and correction
procedures. The first assesses if the estimated service area omits a sizable
share of voucher holder locations (so is “too small”), and if so, adjusts to
include census designated places or counties containing at least 5 percent of a
PHA’s voucher holders.<span>  </span>The second test
checks whether the estimated service boundary includes areas the PHA does not
appear to serve and that are clearly served by another PHA (so is “too large”),
in this case adjusting by removing those areas. 148 of the 377 PHA estimated
service areas were found to be too small, too large, or both, and so have
revised service areas that differ from HUD’s estimated service areas. The
detailed methodology is provided below. Additionally, a spreadsheet is supplied
that identifies geographies that were added to and dropped from HUD’s estimated
services to create the revised service areas for affected PHAs.</font></span></p>
