What XH1B calculates / Local wage comparisons
How to read the wage comparison
County averages mix occupations and years. Offered wages and the latest available national BLS occupation medians are averaged separately over available records, so their populations can differ. This is a screening comparison, not a comparison of matched filings or a finding about an individual wage.
Definitions & methodology ↗Filings & wages
Annual filing records and a county-level wage comparison.Filing history
Annual DOL filing records. Workers requested are not confirmed hires.
Inspect filing outcomes All available years and DOL statuses
Certified, denied, and withdrawn counts describe application decisions. They do not measure visas issued or workers hired.

How this distribution is built Year-unit offers, all outcomes and visa classes
The distribution covers positive offers with wage unit Year, across all outcomes and visa classes. It differs from the certified H-1B summary cohort. It does not adjust for occupation, employer, or worksite mix.

52 notices filed
Σ workers×(1+wage_gap) + Σ WARN layoffs. The 1.0 base rate per certified H-1B worker request is a site model assumption. Wage gap multiplier = (BLS median − offered wage) / BLS median, applied only to filings offering less than the BLS median. Related research provides context, not validation of these exact coefficients. This is a modeled estimate, not a count of actual displacements. WARN layoff counts are government-reported.
Exposure method v1.2 · This is a modeled worker-equivalent count.
Modeled consequence estimates
Conditional impacts associated with modeled displacement
These are conditional population estimates scaled from Linn County's current modeled displacement count. They are not observed outcomes, a prediction about any person, or evidence that this entity caused displacement.

Excess deaths over 20 years

Illustrative reference calculation · population applicability is not established
$8.5B
Range: $2.2B to $14.4B
Canadian father–son firm-closure effect, applied to a US male lifetime-earnings baseline in 2024 dollars. The reference result uses 2 children per worker.
Baseline population: US male median lifetime earnings.
The mortality effect comes from a high-seniority male study cohort. Treat the count as a reference scenario unless the population matches. A mixed population needs a reviewed transport rule.
The range is the engine's parameter-support envelope: it varies declared parameters only and adds none of the exposure input's uncertainty.
The math, limits, and citations
Illustrative reference calculation scaled by the supplied worker-equivalent exposure. Two children per worker; 20-year mortality follow-up. This does not establish that an entity caused these outcomes.
