Brooks-Powers asks IBO to expand on data constraints. Armbruster says IBO cannot identify serious mental illness specifically in its data, nor substance use disorder or domestic violence histories, though those factors matter for programs and diversion.

Selvena N. Brooks-Powers

Thank you for that.

Selvena N. Brooks-Powers

You mentioned data constraints.

Selvena N. Brooks-Powers

Can you expand on that?

Selvena N. Brooks-Powers

What data do you need?

Arden Armbruster

So I think in particular with this analysis, what we wanted to make clear is that this intersection of mental health needs and housing needs is not the only intersection that people should be aware of.

Arden Armbruster

So something, for example, we don't look specifically at serious mental illness because in the data that we have available, we don't have a marker for that specifically.

Arden Armbruster

So data limitations like that, similarly substance use disorder or a history of experience with domestic violence, those other factors that are often considered when

creating programs and diversion programs for these populations.
