Boston ranks No. 4 among major U.S. cities with the worst housing shortages, according to an analysis by Angi.

Angi used data from Freddie Mac and Realtor.com to assess population trends, available housing and home price index percentage changes. It also measured available affordable housing to arrive at its ranking of the 10 cities facing the “worst housing shortage.”

The analysis pointed to construction slowdowns during the COVID-19 pandemic as one factor in creating housing shortages. It also noted that much of what is available is out of the price range for many locals. “Simply put, what is available isn’t affordable,” the report said.

The cities with the worst housing shortages, according to Angi, in order: San Jose, California; Washington, D.C.; San Francisco; Boston; Miami; Boulder, Colorado; Salt Lake City; San Diego; Minneapolis; Los Angeles.
