Over 38 million American households can’t afford their housing, an increase of 146 percent in the past 16 years, according to a recent Harvard housing report.
 
 Under federal guidelines, households that spend more than 30 percent of their income on housing costs are considered “cost burdened” and will have difficulty affording basic necessities like food, clothing, transportation and medical care.
 
 But the number of Americans struggling with their housing costs has risen from almost 16 million in 2001 to 38 million in 2015, according to the Census data crunched in the report. That’s more than double.
