To direct the Secretary of Housing and Urban Development and the Director of the Bureau of the Census to conduct a study and submit a report about how Federal agencies identify and record cases of housing loss in the United States, and for other purposes.

HR 3988 requires the Department of Housing and Urban Development (HUD) and the Census Bureau to jointly study how federal agencies track and record "housing loss" in the U.S. Housing loss is defined as involuntary displacement, including evictions, foreclosures, or displacement from natural disasters. The study must identify common types of housing loss, review existing federal data sources, assess data quality, and recommend improvements for better tracking. HUD and the Census Bureau must submit a report to Congress within six months detailing these findings and recommendations. This bill does not change current laws but mandates a federal review to improve how housing loss is measured.
