Why It Matters

The United States faces a housing shortage despite adding millions of new units over the past quarter-century. According to a new Congressional Research Service (CRS) report on housing supply, the total inventory of homes available for sale has collapsed from approximately 2.35 million in 2000 to roughly 1.3 million in 2025, even as total housing units grew 23 percent.

When adjusted for population growth, the picture worsens: housing units per capita have actually fallen 3 percent over the same 25-year period, suggesting the nation is falling further behind demographic demand. The Trump administration has identified federal policy levers, including tax policy, grants, trade, interest rates, and labor supply, as tools that can affect housing supply.

The Big Picture

The housing crisis stems partly from a post-2008 construction collapse that has never fully reversed. Single-family housing starts peaked at roughly 170,000 per month in 2006, then plummeted to approximately 30,000 per month in 2010, and have only recovered to around 60,000 per month as of 2025. When adjusted for population growth, combined starts across all unit types fell 31.1 percent from 2000 to 2024, even as the nation added tens of millions of residents.

Multifamily construction has partially offset the single-family decline, growing from roughly 10,000 units per month in 2000 to approximately 60,000 per month in 2025. Manufactured housing, which once provided affordable supply, collapsed from roughly 15,000 units per month in 2000 to just 1,000 units per month by the late 2000s and has remained stuck there through 2025.

The existing home inventory fell from approximately 2.25 million in 2000 to approximately 1.2 million in 2025, reflecting both the post-crisis construction shortfall and the tightening of the resale market.

The Bottom Line

Closing the housing supply gap will require action on multiple fronts. The Trump administration's policy choices on tariffs, immigration enforcement, and housing finance programs will shape whether construction can accelerate fast enough to meet demographic demand. Recent legislation, including the 21st Century ROAD to Housing Act (enacted July 2026) and increases to the Low-Income Housing Tax Credit authority under the FY2025 Budget Reconciliation Law, represent steps toward expanding supply, but the CRS analysis suggests these gains could be offset by rising construction costs and labor shortages if cross-cutting policies remain unchanged.
