Positions are approximate. Figures come from each company's latest accounts; money and employee figures are compared only with companies that filed accounts in pounds for a period ending in the last two and a half years and are not dormant, so those groups are smaller than 6,507. The line on each bar marks the median.

Figures the company reported itself to the government's Check payment practices service, Gender pay gap service and Modern slavery statement registry (Open Government Licence v3.0). Only large companies and employers with 250 or more staff have to report, so most companies have nothing here.
