The mean gender pay gap is the percentage difference in the average pay of men and women. This is calculated by adding up all the hourly pay rates for all the women in a business and dividing it by the number of women, then doing the same for the men and comparing the difference. The mean can be affected by different numbers of men and women in different roles. Therefore, we also report the number of men and women in different pay quartiles.
We also report the median and mean differences in bonus pay over a twelve-month period, and the percentage of men and women who received a bonus. A positive percentage shows a gap in favour of men; a negative percentage shows a gap in favour of women.
