Executive Summary

On 13 May 2026, the Federal Council took note of an external study analyzing the consequences of limiting Switzerland's permanent resident population to 10 million people. The State Secretariat for Migration (SEM) commissioned the investigation to fulfill two parliamentary motions. The study models impacts on the economy, social insurance systems, and EU relations and is being published immediately before the vote on the popular initiative "No 10-Million Switzerland!"

The publication is deliberately timed close to the planned popular vote on the sustainability initiative and aims to bring transparency to the opinion-forming process. The study provides concrete fiscal scenarios for a long-term planning horizon extending to the year 2100 — relevant for decision-makers in parliament and administration who must assess the long-term consequences of migration restrictions. The results indicate substantial trade-offs between relief effects and economic costs.

Detailed Summary

The study combines existing population scenarios with restriction models and was accompanied by an inter-departmental working group led by the SEM, with participation from the Federal Department of Foreign Affairs (FDFA), the Department of the Interior (DI), and the Department of Economic Affairs (DEFEA). It fulfills the Broulis postulate (24.4038) on age structure and pension systems as well as the Binder-Keller postulate (25.4276) on cost-benefit analysis of labor migration.

The analysis presents a differentiated picture: Relief effects emerge in the housing market, infrastructure, the environment, and needs-based social benefits such as supplementary benefits and social assistance. However, these relief effects are significantly smaller than the identified costs. Fiscally particularly serious: The AHV pay-as-you-go balance deteriorates over decades by several billion francs annually, tax revenues decline more sharply than expenditures, and the share of health costs in national income grows disproportionately. Structural challenges such as demographic aging, skilled labor shortages, and rising health costs would, according to the study, further intensify.

The study emphasizes its limitations: It describes scenarios, not forecasts. The concrete impacts depend substantially on how a population limit is designed, and the quantitative results for the long-term horizon are subject to considerable uncertainties.

Key Findings

  • A population limit of 10 million would result in substantial fiscal costs over decades
  • Relief effects in housing, infrastructure, and the environment are quantitatively smaller than the costs
  • Demographic and economic challenges (aging, skilled labor shortages) would intensify

Critical Questions

  1. Evidence/Data Quality: What empirical foundations and population forecasts underlie the scenarios, and how sensitive are the results to assumptions about birth rates and life expectancy?

  2. Conflicts of Interest: To what extent could close oversight by federal departments (SEM, FDFA, DI, DEFEA) have influenced the orientation of the analysis toward migration policy or economic priorities?

  3. Causality/Alternatives: Does the study model alternative measures to address aging and skilled labor shortages (e.g., productivity increases, employment rates) as counter-hypotheses?

  4. Feasibility: How realistic are the assumed scenarios for implementing and designing a population limit (e.g., exemptions, control mechanisms)?

  5. Long-Term Horizon: How reliable are quantitative statements for a 75-year horizon (to 2100) given technological, political, and demographic uncertainties?

  6. Accounting Method: Does the overall assessment also consider qualitative factors such as innovation capacity, cultural diversity, or international competitiveness, or does the study primarily focus on measurable fiscal variables?
