Headcount as the company states it in Item 1 of its annual report (some count full-time equivalents or exclude part-time and temporary staff), at the date it gives. Years where the report states no clear total are left out rather than estimated. Changes can reflect acquisitions and disposals as well as hiring and job cuts.
