The data used in for this map is the official UK GPG reports from 2018-19.

The median GPG is used as identifying the wage of the middle earner is the best representation of the ‘typical’ gender difference because the median is less influenced by outliers than the mean.

The median hourly GPG reflects the hourly pay as percentage of men's pay (i.e. if the GPG is 22% it means that women on average earn 22% less than men). Remuneration provided otherwise than in money (e.g. vouchers) are excluded from the ordinary pay measures. Yet salary sacrifice vouchers (e.g. childcare) is calculated into the ordinary pay.
