As the International Women's Day reaches its centennial anniversary, men still take home disproportionately higher pay than women in 370 of the UK's 426 job classifications. While women earn more in only 53 categories, according to data supplied by the Office for National Statistics and analysed by the Guardian. Equal pay prevails in three job categories only.

The biggest disparity is in steel foundries and other parts of the metal-making and treatment industry, with men's median annual pay 52% ahead of women's. Second is the brokerage industry, where men earn 42.4% more in their annual salaries.

The average man working full-time has a median salary, including overtime, of £28,091 in 2010, 19.9% more than his female counterpart, according to the ONS. The gap falls to 10.2% when overtime - which typically pays a much higher rate and is largely carried out by men - is eliminated by comparing hourly rates, which is the favoured measure for the ONS.

The pay gap has narrowed considerably in the past decade, from 16.3% (excluding overtime) in 2000 to 10.2% last year in hourly full-time wages. But the gap is far from being bridged and continues to attract almost universal condemnation.
