Social Security Trustees Revise Down Fertility Projections, Raising Program Solvency Concerns

The Social Security trustees released their annual report projecting a decline in the national fertility rate to 1.75 over the next 25 years, down from 1.9 projected the previous year. However, the current fertility rate has already fallen to 1.6, the lowest in a century according to CDC data, and other government agencies project even more conservative figures—the Census Bureau projects 1.61 by 2045 and the Congressional Budget Office assumes a long-run decline to 1.53. This discrepancy raises concerns that the trustees' projections may be overly optimistic, potentially masking the true magnitude of Social Security's funding challenges. The lower fertility rate directly impacts the program's solvency, as fewer workers will be available to support retirees through payroll taxes. The Social Security retirement trust fund's projected 75-year solvency gap widened from 3.82% to 4.42% of taxable payroll, with lower fertility projections accounting for approximately half of that deterioration. Experts warn that declining fertility will also have broader economic consequences, including slower labor force growth, reduced tax revenues, and larger federal budget deficits.
