Active role records, by age
These figures use Koppers Holdings Inc.'s records marked active, excluding likely evergreen listings. Undated records count as active but do not contribute to posting ages. Role observations may be incomplete; these are not hiring or time-to-fill measures.
Historical records by posting-date cutoff
Includes active and inactive records with employer posting dates on or after each cutoff, excluding likely evergreen listings. These are historical date totals, not current openings or first appearances. Dates have no upper cutoff, so future-dated records can be included.

Recorded appearance and removal events
Events recorded by the tracker, grouped by event month. These are not posting-date totals or a count of current openings; one role can have multiple events. Reappearance events are not included in these totals. The event history may be incomplete.
