Pay ratios show women's pay as a percentage of men's pay (100), not the gender mix of the workforce. Men's childcare leave rates may exceed 100% due to the timing of leave. Sector comparisons use companies with the same calculation basis.
Figures come from each annual report. Temporary employees are annual averages shown separately and are not added to employee counts. Salaries flagged for review are omitted.
Sector comparisons use each listed peer's latest reported period, which may differ between companies. Medians require at least five available observations and exclude flagged salaries. Rankings are largest first and do not indicate quality.
