Overview
- The 30-year projection shows the population rising from about 349 million in 2026 to 364 million in 2056 before declining thereafter.
- Net immigration is expected to be the only source of growth after 2030, with the CBO warning that future laws and enforcement changes could significantly alter the path.
- Stricter immigration enforcement, including measures funded in the 2025 Reconciliation Act, is estimated to reduce the population by roughly 320,000 over the next decade.
- CBO lowers its long-run fertility assumption to about 1.53 births per woman and projects fewer births among women under 30 with modest increases among women over 30.
- An aging population and slower labor-force growth pose budget pressures, with the CBO highlighting significant implications for Social Security and Medicare.
