Since 2000, rents have risen while the number of renters who need low-priced housing has increased. These two pressures make finding affordable housing even tougher for very poor households in America. Nationwide, only 28 adequate and affordable units are available for every 100 renter households with incomes at or below 30 percent of the area median income. Not a single county in the United States has enough affordable housing for all its extremely low-income (ELI) renters.
