JoTrAn.AI | Job Trend Analysis

This page shows which sources were actually checked, every row returned, every exclusion, every exact-ID overlap and the final unique US requisitions kept. It describes data collection, not confirmed hiring.

Source-by-source evidence

Live employer sources and archive captures use different arithmetic, so they are shown in separate tables.

Current employer sources

Source	Company	Query hits	Repeated across queries	Outside named AI org	Outside US	Could not verify	Current US jobs	Checked	Evidence

Historical archive captures

Archive source	Company	Rows captured	Repeated in archive	Outside US	Same ID live	Could not verify	Historical-only added	Capture date	Evidence

Other source connections

Connected, manual and unavailable discovery sources are disclosed even when they contribute no jobs. Discovery-source candidates are never counted until an official employer requisition confirms them.

Data completeness for job statistics

Shows how many loaded jobs actually contain salary, experience or title-skill information. Missing values are never guessed, treated as zero or included in averages.

Detailed requirementsNot collected

What this shows: Availability of fields used in calculations. How calculated: Coverage = jobs with an employer-published value divided by all loaded jobs under the selected company and source filters.

Historical coverage gaps and next steps

The archive-source arithmetic appears once in “Source-by-source evidence” above. This section shows whether each target company has enough historical evidence to support a trend.

Backfill coverage by target company

What this shows: Why some companies have archive history and others do not. “Candidate lower-bound found” means official archived detail pages exist, but they are not a complete company-wide record and are therefore not yet used in trends. Zero added jobs means “not imported,” not “the company had no jobs.”

Trend and comparison graphs

All four charts use the same selected jobs and date ranges, so their totals match the numbers above.

Jobs through the selected dates

Current vs comparison

Each pair of bars counts jobs published in one equal slice of time. Color shows company; solid is the current dates and pale is the comparison dates. The number above each bar is the job count.

Jobs by company

Posting count

Each company has two bars: solid for the current dates and pale for the comparison dates. The number beside a bar is the confirmed job count.

Jobs by region and company

CA vs NY vs rest of US

Each bar counts jobs in that region and is split by company. The label shows the job count and its percentage of all selected US jobs. Multi-location requisitions are counted once using the primary US location retained.

Jobs by function and company

Top functions by volume

Each bar counts jobs in that type of work and is split by company. Solid is the current dates; pale is the comparison dates.

Company comparison

Compare each company's confirmed US jobs, where they are located, and the salary and experience information employers published.
