Economic Impact of Ending Birthright Citizenship

Key Concepts

• Birthright Citizenship: The legal principle that citizenship is determined by place of birth rather than the citizenship of one's parents.
• Economic Contribution: The total value added to the GDP by a specific demographic group through labor and consumption.
• Labor Shortages: The gap between the demand for labor and the available supply, exacerbated by an aging U.S. population.
• Underclass: A socioeconomic group lacking access to legal status, education, and professional opportunities, potentially created by the removal of birthright citizenship.
• Conservative Estimation: A methodology that uses the lowest reasonable assumptions to ensure findings are not overstated.

1. Economic Impact and Projections

The study estimates a $7.7 trillion loss to the U.S. economy over the next few decades if birthright citizenship for children of undocumented or temporary immigrant parents is revoked.

• Scope: This figure accounts for the lifetime contributions of individuals already in the workforce, as well as future generations yet to be born.
• Geographic Concentration: The impact is not uniform. California and Texas alone account for one-third of the total economic effect, with estimated losses of over $2 trillion and $1.5 trillion respectively.
• Methodology: Researchers used current data on working-age individuals who benefited from birthright citizenship to project the future economic output of children and future beneficiaries. They analyzed current employment sectors, earnings, and labor market participation.

2. Impact on Labor Markets and Industries

The study identifies specific sectors that would face significant disruption if the labor supply provided by this demographic were curtailed:

• Top Impacted Sectors: Office administration, construction, and architecture are projected to be hit hardest.
• Long-term Consequences: Because these individuals would lack legal status, they would likely be barred from post-secondary education. Since nearly two-thirds of current beneficiaries work in industries requiring higher education, the U.S. would lose a significant portion of its skilled workforce.
• Synergistic Effects: The loss of this labor force would exacerbate existing labor shortages caused by the aging U.S. population and current mass deportation policies, potentially rendering some industries unable to function effectively.

3. Methodological Framework

The researchers employed a "long-term accounting exercise" rather than a short-term political analysis:

• Conservative Approach: The $7.7 trillion figure is considered a conservative estimate. Depending on the assumptions applied to the data, the actual economic loss could be as much as double that amount.
• Non-Retroactivity: The experts noted that if an executive order were implemented, it would likely not be retroactive. Therefore, the most severe economic impacts would unfold over the next several decades as the affected cohorts reach adulthood.

4. Global and Societal Perspectives

• The "Underclass" Argument: The researchers argue that removing birthright citizenship would create a permanent underclass of individuals who, unlike in other countries with different citizenship models, lack clear pathways to naturalization or legal status.
• International Comparison: While some countries base citizenship on parentage rather than birthplace, they typically provide established legal pathways for children of temporary residents to naturalize. The U.S. lacks such mechanisms, making the proposed policy shift a "very big departure" from both U.S. history and international norms.
• Significant Statement: Philip noted, "It’s a world that we really don’t know of in the United States where birthright citizenship doesn’t exist... it would be an experience that really we don’t comprehend totally because we’ve never seen it before."

Synthesis and Conclusion

The study concludes that birthright citizenship is a critical engine for U.S. economic growth. The potential revocation of this policy would not only result in a multi-trillion-dollar loss to the GDP but would also create a structural labor crisis. By preventing a segment of the population from accessing education and legal employment, the U.S. risks creating a permanent underclass, further straining industries already struggling with labor shortages and demographic shifts. The findings emphasize that the economic consequences are long-term, profound, and geographically concentrated in major economic hubs like California and Texas.
