424 active role records

These records update separately from the snapshot figures above and may include an incomplete collection. Counts can also differ because the snapshot's listed-role count excludes likely evergreen listings and can retain roles since marked removed. Individual posting ages use employer-supplied dates only; records without one show “Posting date unavailable.” Listing age and Newest use those dates too: records without one are listed last and aren't in any age group, and age groups leave out continuous-hiring and evergreen postings, because they stay listed by design.
