Positions count by year

Hover over a name to see the position and date range. This table only includes positions where at least the start date is known. The positions count can count the same person multiple times if they held different positions; similarly, the list of staff may include the same person multiple times if they held more than one position during a single year. For each year, a person is included if they were at the organization for any part of the year; this means the actual staff count at any point during the year can be lower (or higher, if some staff held multiple positions in a single year).
