What it measures
- Unique Certified H-1B case records
- Total requested worker positions
- New employment requests, independently of extensions and amendments
- Matched decision-month comparisons with the preceding fiscal year
What it does not measure
Most misreadings of labor data come from asking a dataset a question it was not built to answer. These are the limits worth holding onto.
- Completed hires, visa approvals or unique people
- Net job creation or all open vacancies
- A direct replacement for job-posting or payroll measures
- A component of Job Market Health scores
Update cadence
Quarterly disclosures; file coverage varies.
Occupation pages name the specific release behind each figure and when it was imported, so you can see how current a number is rather than assuming it is new. More on that on about the data.
How JobMarketHealth uses it
- The H-1B Demand page uses a validated committed aggregate snapshot; visitors never request DOL files.
- Case-level duplicate rows count once; conflicting duplicates stop the import. Certified - Withdrawn, Denied, Withdrawn and other visa classes stay outside position measures.
- Employment categories can overlap and are never summed as a hiring total. Exact detailed DOL codes are preserved without an assumed BLS crosswalk.
- Source-check dates, decision windows and file checksums are displayed separately. Single-quarter and cumulative file coverage are validated separately, never blindly stacked.
Where it sits
This dataset is displayed as context on the pages described above and is not an input to the score. Read the methodology.
