This Congressionally mandated study of the current (or "backlog") modernization needs of the public and Indian housing stock is one of the most complex research and cost estimation projects ever funded by the Department of Housing and Urban Development. New methods of measuring and costing modernization needs were specially developed for this project. These methods were tested, refined, and validated before conducting the full scale study, which involved data collection at more than 1,000 housing developments. Scientific sampling techniques were used to select representative developments, including a variety of project building types (e.g., high rises, townhouse-type buildings) and dwelling units.

This report is part of the collection of scanned historical documents available to the public.
