Measuring the impacts of social housing

Our new working paper Measuring the wellbeing impacts of public policy: social housing - examines the impact of placement in social housing on peoples’ wellbeing. The paper tests a novel method of combining administrative and survey data to connect wellbeing measures with social service usage and includes preliminary results.

The wellbeing measures used are consistent with the wellbeing domains set out in our Wellbeing measurement approach.

Combining survey and administrative data to quantify impact

It is difficult to know if or how social support makes a difference in people’s lives without robust evaluation of those impacts. Administrative data can provide good information on service use over time, but not a measure of service impact, or outcomes. Survey data often has good outcome measures, but typically lacks information of service usage and how this changes over time. Our social housing working paper examines the impact of social services on people’s lives. It does this by linking administrative data and survey data to quantify the impact of social services in terms of the actual wellbeing outcomes experienced by a small sample of people, before and after living in social housing. Although we identified a number of methodological challenges in the analysis of social housing outcomes, the use of linked survey and administrative data in this way has strong potential to be applied to other areas of social policy.

The impact of social housing on New Zealander’s wellbeing

A small sample size and difficulty in identifying people before they move into social housing mean that the results of our analysis are experimental and should not be seen in isolation from other research on the impact of social housing. However, our analysis suggests wellbeing improves for people who move into social housing. They experience improved housing quality and more free time, but report lower feelings of safety in their new neighbourhood. People also report a higher overall satisfaction with their lives.

Toward the end of 2018 we will re-execute the research with the inclusion of Statistics NZ’s latest New Zealand General Social Survey data. We look forward to sharing the results early in 2019, which, together with this working paper, can support housing agencies’ own thinking when developing housing policy.
