Black, Asian and minority-ethnic staff (BAME) who work at PwC in the UK earn almost 13% less than other employees, according to figures provided by the professional services firm.
The firm said its BAME workers were statistically paid less because more of them worked in administrative and junior roles, rather than senior ones.
PwC said it had published the data to help it speed up progress on the issue.
Currently reporting on BAME pay isn’t required under government regulations.
PwC said it hoped that publishing the data would help the firm to tackle “ethnicity challenges”.
“The more transparent we are with our diversity and social mobility data, the more we hold ourselves accountable to achieving real change,” said PwC chairman Kevin Ellis.
