# ZIP 07976: H-1B profile

> ZIP profile: https://www.xh1b.org/zip/07976 · [county](https://www.xh1b.org/county/34027)

Employers in 07976 (NJ) filed 1 certified H-1B application requesting 1 worker across 1 company. The median offered wage is $100,000/yr. The displacement model assigns 1 worker-equivalent exposure to these filings.

| Metric | Value |

| H-1B filings | 1 |
| Workers requested | 1 |
| US workers displaced (modeled) | 1 |
| Distinct employers | 1 |

| Average prevailing wage | $90K |
| Average BLS market wage | $102K |

Headline filing and employer counts use certified H-1B records. The below-prevailing share uses filings with offered wage data as its denominator. Offered, prevailing and BLS averages use independently available values; their populations can differ. The BLS reference averages national occupation medians linked to certified filings, using each occupation's latest available year. It is not a ZIP-wide market median. The employer list includes all LCA outcomes and visa classes; quality-flagged rows are excluded.

## Modeled consequence estimates

**Conditional impacts associated with modeled displacement**

These are conditional population estimates scaled from ZIP 07976's current modeled displacement count. They are not observed outcomes, a prediction about any person, or evidence that this entity caused displacement.

20-year reference scenario: high-seniority male displacement effect. This is not an expected count for an unknown population.

Source-profile mortality point (deaths): 0.0292763860228

No sustained excess from year 7 (deaths): 0.0208927719419

Declared structural comparison; not a confidence interval or a model probability.

Baseline population: US prime-age men (45-54).

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.

Exact values: excess deaths over 20 years 0.0292763860228 (range 0.011465006811 to 0.0509973258614); child lifetime earnings lost $487,514.14 (range $126,627.05 to $823,075.82);

The displayed range is a parameter-support envelope, not a confidence interval.

Place reference: national reference.

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.

Outcome statistics use the displayed exposure. Baselines, coefficients, annual family schedules and component records retain their source normalization.
