The headcount was then converted (by gender and five-year age group) into the full-time equivalent using the assumed values for average usual weekly working hours. “ Full-time” in this instance refers to usual weekly working hours equal to 40 hours per week, so the FTE labour force was calculated as the headcount labour force multiplied by the usual weekly working hours of the relevant group, divided by 40. Figure 3.A2.1 shows the resulting estimates for the projected size of the German full-time equivalent labour force (15-74 year-olds).
