## Premium Fields Explained

### Display and Raw Variants

Premium includes additional name variants and the original source data:

* **`name.display`**: Best-quality company name with original casing preserved (e.g., `"FoodPop"`, `"AT&T"`) — ideal for UI rendering
* **`raw[]` arrays**: Original source data alongside cleaned values for `name`, `headline`, and `description`

These are valuable for:

* **Customer-facing UIs**: Render company names with correct casing
* **AI/ML training**: Preserve original formatting for model training
* **Data lineage**: Trace values back to original sources
* **Advanced matching**: Use variations for fuzzy matching

### Workforce Analytics

All fields with the `legion_` prefix are derived from our person data and only available in Premium:

* **Employee counts and growth**: Track workforce size changes over 1, 3, 6, and 12 month windows
* **Hiring and attrition**: Monitor new hires and departures by time period
* **Workforce distributions**: Breakdown by seniority, job function, expense category, tenure, and education
* **Distribution growth rates**: Growth rates per seniority level, job function, and expense category
