HMRC do not produce statistics separately for child tax credit and working tax credit.
However, estimates of the number of families with tax credits in 2003-04, 2004-05 and 2005-06 in each constituency, based on final family circumstances and incomes, are produced in Table 3 of the HMRC publications ‘Child and Working Tax Credits. Finalised Awards. Geographical Analysis’ for each relevant year. These are available on the HMRC website at:
The number of out-of-work families includes those who are receiving the equivalent level of support via income support and jobseekers allowance.
Information on the average annual entitlement for families in each constituency is also available in Table 3 of these publications.
The same information for 2006-07 is due to be published on 20 May 2008.
