This bill requires the Congressional Budget Office, working with the Council of Economic Advisers, to produce and publish a study on the 20–40 year economic impact of immigration policies that took effect beginning January 20, 2025. The study must analyze industry-specific effects, demographic and migration flows, productivity and innovation, impacts on small businesses and consumer activity, public safety-related effects, and federal, state, and local fiscal consequences.
The statute also compels key agencies—the Department of Homeland Security, Bureau of Labor Statistics, and Internal Revenue Service—to provide data to the CBO on request. For analysts and policymakers, the bill creates a mandated, cross-agency empirical product focused on long-range economic and fiscal consequences of a specific set of administrative immigration actions.
At a Glance
What It Does
Mandates a publicly available CBO study, conducted in collaboration with the CEA, assessing the twenty- to forty-year economic effects of immigration policies implemented beginning January 20, 2025. It lists six analytic elements (industry breakdowns, public safety effects tied to fear, migration flows and demographics, productivity and innovation, small business impacts, and tax/revenue consequences) and requires interagency data sharing on request.
Who It Affects
Federal budget and economic analysts, CBO and CEA staff, DHS/BLS/IRS as data providers, state and local fiscal officers who may be evaluated in the study, and private-sector employers in agriculture, healthcare, services, and STEM-dependent industries whose future labor and tax contributions are subject to analysis.
Why It Matters
It forces a formal, long-range economic accounting of a defined set of immigration policies, creating a single authoritative federal analysis that could inform future legislative or administrative action. The law also creates practical obligations for data sharing and sets the analytical horizon unusually long (20–40 years), which shapes methodology and interpretation.

What This Bill Actually Does
The bill commands the Congressional Budget Office to produce a public study about the long-term economic effects of immigration policies that went into effect starting January 20, 2025. The CBO must work with the White House Council of Economic Advisers on the project.
The study is explicitly forward-looking: it must estimate outcomes over a 20-to-40 year window rather than just short-term fiscal impacts.
The statute specifies the topics the study must cover. Those include how different sectors—public sector employers, service and farm workers, health-care workers, and STEM-related academic and professional retention—will be affected; how fear-driven changes in public behavior might influence public safety and crime; the size and composition of future migration flows and demographic changes; effects on productivity, innovation, remittances, consumer spending, investment, and GDP contribution; consequences for small businesses; and net fiscal implications at the federal, state, and local levels.To do the analysis, the bill gives the CBO the ability to request and obtain data from three agencies: DHS, the Bureau of Labor Statistics, and the Internal Revenue Service.
The statute requires those agencies to share data the Director of CBO deems necessary and appropriate. Finally, the bill sets a firm timing consideration: the CBO must complete and publish the study by the earlier of 180 days after enactment or the last day of the 119th Congress, which creates a compressed window for a long-horizon analysis.Taken together, the measure creates a legally mandated, cross-agency empirical product focused on how a specific set of immigration policies may shape the U.S. economy and fiscal picture decades forward.
Because the study is public and enumerates precise analytic elements, it will likely be used by state fiscal offices, industry groups, researchers, and lawmakers to support or challenge policy choices moving forward.
The Five Things You Need to Know
The CBO must complete and publish the study within the earlier of 180 days after enactment or the last day of the 119th Congress, imposing a tight deadline for a 20–40 year projection.
The study must be conducted by the Director of the CBO in collaboration with the Council of Economic Advisers, explicitly tying CEA participation into the analysis.
Congress specifies six required analytic elements, including explicit industry breakdowns (public sector, service, farm, healthcare, STEM retention), public-safety effects linked to pervasive fear, migration flows and demographic change, productivity and innovation metrics, small-business impacts, and federal/state/local fiscal effects.
DHS, BLS, and IRS are statutorily required to share data with the CBO upon request—leaving the scope, format, and confidentiality handling to CBO’s determination of what is 'necessary and appropriate.', The geographic fiscal assessment must address net fiscal impacts of 'mass deportation' scenarios at the federal, state, and local levels rather than limiting the analysis to federal budgetary effects.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Gives the Act its name: the 'Studying Disastrous Impacts of Mass Deportation Act.' Though ceremonial, the title signals the bill’s focus and frames the study’s subject in politically charged terms, which could affect perceptions of the study’s neutrality even though the operative provisions only mandate analysis.
Mandate for CBO study and collaboration with CEA
Directs the Director of the Congressional Budget Office to conduct and publish a study on the long-term economic impact of immigration policies that were implemented and in effect beginning January 20, 2025. It requires collaboration with the Council of Economic Advisers, making the White House economic shop an explicit partner in designing or reviewing methodology and findings. The clause sets public availability as a requirement, so the final product must be accessible to outside stakeholders.
Scope and analytic elements (20–40 year horizon)
Lists six discrete areas the study must assess: industry-level impacts (including public sector, service, farm, healthcare, and STEM retention), public safety and crime impacts tied to fear, migration flows and demographic shifts, productivity/innovation/remittances/consumer and investment effects, small-business impacts, and tax revenue/fiscal effects at federal, state, and local levels. The 20–40 year horizon forces long-run modeling choices (population projections, labor force participation, capital accumulation) rather than short-term budget scoring.
Data sharing requirement from DHS, BLS, and IRS
Requires the Department of Homeland Security, Bureau of Labor Statistics, and Internal Revenue Service to share data with the Director of CBO upon request, limited to what the Director determines 'necessary and appropriate.' The provision creates an affirmative interagency duty to cooperate, but leaves substantive decisions about data needs, aggregation, and confidentiality handling to CBO discretion—raising operational questions about access, formatting, and legal constraints on tax and immigration data.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Federal and state policymakers: They gain a single, mandated federal analysis focused on long-run economic and fiscal consequences tied to a defined set of policies, which can be used to inform legislation or administrative decisions.
- Academic and independent researchers: The public study and the forced data-sharing mechanism could expand access to aggregated administrative data and produce reproducible estimates useful for peer-reviewed work.
- Industries reliant on immigrant labor (agriculture, healthcare, hospitality, construction, and certain STEM employers): A formal analysis could quantify future labor shortages, productivity losses, or tax-base changes that firms and trade groups can use in planning and advocacy.
Who Bears the Cost
- Department of Homeland Security, Bureau of Labor Statistics, and Internal Revenue Service: These agencies must allocate staff time and resources to respond to CBO data requests and to prepare datasets in forms CBO deems necessary, possibly diverting resources from other priorities.
- Congressional Budget Office and Council of Economic Advisers: CBO must assemble long-horizon models and the CEA must collaborate within a compressed statutory timeline, imposing analytic and resource burdens on both offices.
- State and local fiscal officers and small businesses: If the study highlights negative local fiscal impacts, jurisdictions and small businesses could face political pressure or policy responses (e.g., recruitment incentives or compliance costs) as a result of publicized findings.
Key Issues
The Core Tension
The bill balances two legitimate goals—producing authoritative, long-term evidence about major immigration policies versus the practical limits of attribution and data confidentiality: policymakers want definitive answers about long-run economic and fiscal effects, but rigorous, unbiased causal inference over decades requires assumptions and data that may not exist or that agencies cannot legally disclose, meaning clarity will come at the cost of increased model dependence and potential legal and operational friction.
The bill creates several practical and methodological challenges. First, projecting 20–40 years into the future requires assumptions about fertility, migration, productivity growth, technological change, and policy persistence—each of which carries substantial uncertainty.
CBO will need to choose baseline scenarios and counterfactuals carefully; different plausible assumptions could yield materially different conclusions. Second, the statutory requirement that DHS, BLS, and IRS 'share such data' leaves open legal and operational constraints.
Tax return data are protected under strict confidentiality rules; immigration records implicate privacy and operational security concerns. Translating administrative records into usable, de-identified microdata or aggregated series will require negotiation and possible statutory interpretation.
Third, the bill’s political framing and the mandated collaboration with the CEA create optics issues. While CBO is conventionally nonpartisan, pairing it with a White House office and invoking a charged short title risks perceptions that the study is political rather than purely technical.
Finally, attributing long-run economic outcomes to a discrete set of administrative policies implemented beginning on a single date is inherently difficult; demographic trends, global shocks, and unrelated domestic policies could confound causal inference, limiting the study’s ability to produce definitive causal estimates rather than scenario-based projections.
