Hillingdon is one of the highest areas in the country for abortion rates, a Government study has found.
The statistics were obtained from the abortion notification forms returned to the Chief Medical Officers of England and Wales.
This is higher than the London average of 22.8 and well above the national average of 16.6.
This is despite an overall fall in abortion rates in Hounslow and Ealing.
The research also found that the number of aborted Down's Syndrome babies in England has risen by 50 per cent over the last ten years nationwide.
The Department of Health says one possible reason for the rise is the increase in the average age of expectant mothers - risks of disability are higher the older a woman is when she becomes pregnant.
There were 590 babies aborted under Ground E of the 1967 Abortion Act because of the condition in 2013, compared with only 401 in 2003.
This is in comparison to a rise of 22 per cent for all Ground E abortions over the same period.
