The Effect of New Market-Rate Housing Construction on the Low-Income Housing Market

Mast

Main finding

Moves into new market-rate buildings open older homes throughout the market, and those chains reach lower-income neighborhoods within a few years.

100 new homes led 45–70 people to leave below-median-income tracts within five years

Most important limitation

The chain endpoint is modeled and counts people rather than housing units.

Study chart · redrawn

As moves propagate, the model reaches more below-median-income and rent-burdened neighborhoods.
