Housing mix against assessed need

Supplement P Tables P.5 and P.10

How this region's housing is distributed across design categories, against how its assessed need is distributed. Shares of each side's own mix, because dwellings and people are different units.

Share of enrolled dwellings Share of participants with an SDA need

Shares are renormalised over the four design categories the NDIA reports on both sides. Excluded: 0.7% of dwellings (Basic and Multi-Design Category, which the demand tables do not use) and 9.0% of participants (design category not recorded). Supply from Supplement P Table P.5, need from Table P.10.
