The math
16782 of 24724 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.

Excess deaths over 20 years
Illustrative reference calculation · population applicability is not established
1,653.38
Range: 647.48 to 2,880.07
20-year reference scenario: high-seniority male displacement effect. This is not an expected count for an unknown population.
- Source-profile mortality point (deaths)
- 1,653.3803058
- No sustained excess from year 7 (deaths)

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
$27.5B
Range: $7.2B to $46.5B
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.

Employers & filings
Who files here, and the filings behind every number above.Top employers (3,445)
5 largest employers account for 14% of the 24,724 filings attributed to 3,445 employers here (the records). See the ranking
Context & calculation notes how the share is built
Share = filings by the top 5 employers ÷ all filings in this geography with a resolved employer. Filings whose employer is not yet linked sit outside both numbers, so the denominator can be smaller than the geography's headline filing count.
The share describes this one geography. A high share is a concentration signal for inspection, not a finding about any employer.

What the filing rows show One application per row
Each row links to the disclosure record. The wage badge compares an offer with available benchmarks; it is a screening calculation, not a finding of a wage violation.
Wages & occupations
What wages are being offered, against which benchmarks.Wages
0.01% of the 22,890 filings with a wage on record offer below the employer's own prevailing wage. The prevailing wage is the floor the employer attested to, not a market benchmark.

|---|---|---|---|---|
| $55,000 | $65,000 | $82,000 | $104,166 | $135,000 |
Context & calculation notes wage sources and averages
Offered wages are employer-reported on the DOL record, annualized to year rates. Averages mix occupations and years: a geography-level average is a screening comparison, not a matched-role finding.
The BLS market median is the OES national median for the filing's occupation (latest available year). The prevailing wage is the employer's own attested floor. The two answer different questions and are not interchangeable.
The distribution covers positive offers with wage unit Year, across all outcomes and visa classes. It differs from the certified H-1B summary cohort. Hourly and other wage units are outside this distribution.
