Earlier today, HUD announced that it published a Housing Choice Voucher Dashboard. The dashboard provides information about vouchers at both the state and national levels. It includes budget and leasing utilization information, reserve balance information (it highlights PHAs that have high reserves as a percentage of their budget authority and in absolute terms), attrition, per unit cost trends, and leasing potential. There is also utilization data on special purpose vouchers (HUD-VASH, FUP, Mainstream, etc.). The data is mostly taken from the voucher management system.
