How to read the wage comparison
County wage averages combine occupations, locations, and years. They are a screening comparison, not a finding about any individual filing.
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Certified, denied, and withdrawn counts describe application decisions.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.

The math
5002 of 7591 filings below BLS median
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.
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 Jefferson 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
387.79
Range: 151.51 to 677.57
20-year reference scenario: high-seniority male displacement effect. This is not an expected count for an unknown population.
- Source-profile mortality point (deaths)
- 387.793262142
- No sustained excess from year 7 (deaths)
- 276.489053736
Declared structural comparison; not a confidence interval or a model probability.
Baseline population: US prime-age men (45-54).
Child lifetime earnings lost
Illustrative reference calculation · population applicability is not established
$8.4B
Range: $2.2B to $14.3B
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 calculations per 1,000 displaced workers and a standard family. Not a prediction about an individual or evidence that an entity caused displacement. Only county rows use county place inputs, including their WONDER-derived all-cause mortality baseline; all other types use the national reference.

Exact values: excess deaths over 20 years 387.793262142 (range 151.505239753 to 677.572439181); child lifetime earnings lost $8,437,376,974.93 (range $2,180,985,347.53 to $14,313,439,571.98);
The displayed range is a parameter-support envelope, not a confidence interval.
Place reference: county inputs where the model has a validated county value.
Not included: exposure estimation error; baseline estimation error; unmodeled pathways.
Blocked model paths: local_service_jobs_lost: requires a documented net local loss of tradable jobs; worker displacement alone is not this exposure.
