Explore the Data

Download the data to explore trends over time for MTW agencies and traditional PHAs.

The data include the total number of households assisted and the characteristics of the people residing in those units for 2008–16, for each MTW agency.

With these data, you can

  • explore trends in MTW housing assistance,
  • look at MTW PHA-specific trends in local housing assistance,
  • explore differences between MTW and traditional PHAs over time, and
  • explore variations in households assisted by different types of rental assistance.

About the data

This analysis and the accompanying report use a combination of HUD’s Public and Indian Housing Information Center (PIC) and Voucher Management System data; HUD-provided counts of MTW agencies’ local, nontraditional assistance activities; and US Census Bureau data. The Picture of Moving to Work Agencies’ Housing Assistance appendix describes how we cleaned the data and constructed each of the measures included in the report.

HUD PIC data are the primary source for this feature. They are entered by staff members at over 3,800 PHAs and uploaded to HUD for processing. In any given year, some household records may be omitted from PIC or dropped from our analyses because of data entry errors or processing issues. HUD provided data to the Urban Institute in 2018, and some MTW or traditional PHAs may have updated their PIC or local, nontraditional data later—which could account for any differences between our numbers and those found in later data extracts or in individual housing authority records. In some cases, specific years—notably 2012 and 2013—appear to have missing data for some MTW and traditional agencies or for some programs. It may also be the case that individual MTW agencies aggregate their data slightly differently for their own reporting or program management. Throughout the data-cleaning and analysis process, we worked closely with HUD to understand data quality and coverage, as well as any variations in reporting for MTW compared with traditional PHAs. And MTW agencies reviewed their data to identify any large discrepancies between their internal accounting and our PIC data calculations. We have not adjusted or interpolated the data to address any missing data points.

With these data considerations in mind, minor variations in measures year to year or between MTW and traditional PHAs must be interpreted with caution. There may be slight differences between the data for download file, data visualizations in this feature, and the Picture of Moving to Work Agencies’ Housing Assistance report because of rounding or minor differences in how household-level records and missing data were processed. In addition, minor differences in trends for MTW and traditional PHAs may in part reflect different sample sizes for the two groups of PHAs. Reporting errors for any single MTW agency in a given year can disproportionately affect group averages and trends. Finally, it is not possible to precisely re-create the counts or measures we present in the MTW evaluation reports from publicly available HUD data, given slight variations in how data are accessed, processed, or aggregated.
