A lack of affordable rental housing can push more tenants into substandard or overcrowded living situations, she adds. Housing units within reach for lower income residents might be squeezed up against a highway, for instance, putting tenants in close proximity to noise, traffic, or air pollution, thus increasing their risks for experiencing heart or respiratory problems. Substandard housing also makes lead or mold exposure more likely, possibly triggering serious health issues over time.
The map is part of a broader DPH initiative known as the Sustainable Communities Index, which provides datasets for more than 100 health indicators. There’s a whole section on housing, which even covers the negative health effects of eviction: “Involuntary displacement contributes to stress, loss of supportive social networks and increased risk for substandard housing conditions and overcrowding,” DPH points out.
