Indeed, in this age group, 61 per cent of doctors are now women and 39 per cent men.
In the age group 30 to 50 years, over the same period, the number of female doctors increased by 24 per cent compared with 2 per cent for males. In this age group, men still outnumber women by 54 per cent to 46 per cent — but that ratio will soon reverse.
I fear this gender imbalance is already having a negative effect on the NHS.
The reason is that most female doctors end up working part-time — usually in general practice — and then retire early.
As a result, it is necessary to train two female doctors so they can cover the same amount of work as one full-time colleague.
Given that the cost of training a doctor is at least £500,000, are taxpayers getting the best return on their investment?
There is another important issue. Women in hospital medicine tend to avoid the more demanding specialities which require greater commitment, have more antisocial working hours and include responsibility for management.
Interesting problem, isn’t it?
