Housing insecurity is a growing problem in the United States, and how to best deal with it has been intensely debated. The number of families facing severe housing burdens, meaning they spend more than 50% of their housing income, has increased over the last decade. According to the Center for Economic and Policy Research, nearly 1 in 4 renters were severely burdened by the cost of rent in 2017, compared to 1 in 5 renters in 2001.
