Has housing affordability for young families declined across US metro areas?
Core argument: The authors' Young Family Median Multiple, comparing median personal incomes of individuals ages 20–34 to local median home values, shows just 21% of metro areas met a basic affordability standard in 2018–2022, versus virtually all of them in 1969.
We developed a new indicator we labeled the Young Family Median Multiple (YFMM). It compares the median personal incomes of individuals ages 20-34 to median home values in their local area. Whereas in 1969, virtually every metro area met a basic standard of affordability for young people, in 2018-2022, just 21% did, and over half of the nation’s metro areas were rated as seriously unaffordable for young families, or worse. Between 2012 and 2023, 13.4 million new housing units were completed, while new household formations were 17.2 million, for a supply gap of 3.8 million housing units. Only 9.5 million of these new completions were single-family units.
