Something from Harriet Harman's equality obsessed past

"In June 2009, Sir Michael Scholar, head of the UK Statistics Authority, wrote to Harman to warn her that different headline figures used by the ONS and Government Equalities Office with regards to pay differentiation between men and women might undermine public trust in official statistics. The GEO's headline figure was 23%, which was based on median hourly earnings of all employees, not the 12.8%, based on median hourly earnings of full-time employees only, used by the ONS. Scholar wrote: "It is the Statistics Authority’s view that use of the 23% on its own, without qualification, risks giving a misleading quantification of the gender pay gap". The Equalities Office rejected his criticism, saying: 'With women representing over three-quarters of the part-time workforce, we believe this figure gives the fullest picture of the country's gender pay gap.'"
