Where they came from FY2025 incumbents · previous disclosed position
| Previous position | People | Share | Median yrs in it | Median pay change | Same employer |
|---|---|---|---|---|---|

52 of 115 people (45%) in this position in 2025 came from a position shown here. The rest first appeared on the list in this one, came from a less common position, or had earlier titles that weren't normalized. Previous positions are shown when they're at least 5% of moves and 3 people. Pay change compares salary paid in the last year in the previous position with the first year in this one, so a partial year can skew it. Same employer is the share who made the move without changing employer.

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.
