According to Census 2011, in London that year there were some 4 million jobs, of which 2,1 millions (53,4%) where of males. In the Managers, Directors and Senior Officials there were 300.000 men and 164.000 women, while professional occupations had 461.000 men and 436.000 women. In administrative and secretarial occupations the ratio was 127.000 men for 286.000 women.
The interesting thing is how these jobs are geographically distributed by gender. As yesterday, red lines are the tube.
