Because pay varies considerably between occupations, simple pay gap comparisons between sectors that have different occupational compositions are problematic. Controlling for the effect of the occupational structure of the Public Service gives an adjusted gender pay gap 5 of 8% 6 in the Public Service, compared with 17% for the labour force 7 as a whole. While this is larger than last year's Public Service figure of 6% 8 , this is mostly due to changes to the scope of the survey. If these employees are excluded, the adjusted gender pay gap in 2004 remained at 6%.
As in 2003, just over half the unadjusted gender pay gap in 2004 could be attributed to men working in larger-sized jobs, as measured by established job evaluation methods. However, 27% of the gap was attributed to the occupations women tended to work in being paid less than those men tended to work in, even after factors such as job size, length of service and age were taken into account.
