The report is the twelfth in the series of worst case housing needs reports that have been issued by the Department of Housing and Urban Development (HUD) since 1991.

Worst case housing needs (WCN) are experienced by unassisted very low-income renters who either (1) pay more than one-half of their monthly income for rent; or (2) live in severely inadequate conditions, or both. HUD defines "very low-income" as below 50 percent of the local area median income (AMI) and "extremely low-income" as below 30 percent of AMI.

This report is part of the collection of Affordable Housing & Worst Case Needs Reports to Congress.
