Scotland 2001 comparison:

The table population for 2001 table KS22 differed from the equivalent 2011 table, so the data were re-run using the 2011 KS107SC table population (all lone parent households with dependent children where the lone parent is aged 16 to 74).  The 2001 data are included in the text on pages 20 and 21 of the release 2C bulletin.
