Mr. Michael Foster
To ask the Chancellor of the Exchequer if he will estimate the number of working families tax credit claimants(a) per constituency and (b) per head of population per constituency. 
§ Dawn Primarolo
For the number of recipients of working families tax credit in each constituency, I refer my hon. Friend to my answer to my hon. Friend the Member for Jarrow (Mr. Hepburn) on 16 January 2002,Official Report, column 293W.
I understand from the Office for National Statistics that they do not currently produce population estimates for parliamentary constituencies. I am therefore unable to estimate the number of recipients per head of population in each constituency.
