Raise is the average change for people who held this exact role, in this sector, in both years — not a same-role year-over-year average, which would be skewed by people newly crossing the disclosure threshold or leaving. Promotions is a heuristic (title changed and raise ≥10% in the same year), not verified. Gender is a name-based estimate, shown only for years with 20 or more disclosed employees.
