The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
Letter from Colin Mowl, dated 25 October 2007:
The National Statistician has been asked to reply to your question on the gender ratio for children born in England and Wales in each income decile in the last year for which data is available. I am replying in her absence. (160492)
In England and Wales parental income is not collected at birth registration. I am, therefore, unable to provide you with the statistics you have requested.
