BBC has created a series of data visualizations showing that 78 percent of companies in the UK pay men more than women and that the average pay gap is 9.6 percent, almost identical to the 9.7 percent pay gap firm’s reported in 2018, when the UK first required firms to disclose their pay gap. One reason for the pay gap is that every business sector in the UK has fewer women than men in high-paying, senior roles. For example, four firms in the airline industry have a pay gap of at least 40 percent, largely because men occupy most high-paying pilot roles, while women mostly work in lower-paying stewardess jobs.
