The latest available information is in the following table:

Lone parents are defined as single people with dependants. 3. 16 to 19-year-olds have been included in the sample. 4. The figures have been rounded to the nearest thousand. 5. Figures for any non-responding authorities have been estimated. 6. Housing benefit figures exclude any extended payment cases.

From February 2007, DWP has been collecting more detailed HB/CTB data electronically from local authorities. Over time this will improve the accuracy, timeliness and level of detail available in the published statistics. Quality assurance has been carried out on much of the new data, and the results are published at:
http://research.dwp.gov.uk/asd/hbctb.asp
However, as not all of the detail has been quality assured to publication standard, this particular question can only be answered by using data from the previous detailed data source, which is for May 2004.
