Counting homelessness

We’ve seen in the past that NZ has very high estimated numbers of homeless people by international standards, and that this is at least in part because we have a very broad definition of “homeless”.

In this podcast, journalist Elizabeth Spiers talks to Brian Goldstone about his new book on homelessness in the US, and in part about how the problem is a lot broader than the official homelessness statistics.  His book takes into account the same sorts of people without a home that the NZ statistics do, and his estimate that the true number is about six times the official number would rate the USA as a little worse than NZ.
