To ask the Chancellor of the Exchequer (1) if he will list the 100 wards with the greatest fall in electorate over the last three years, giving the (a) percentage fall, (b) total numbers of electors and (c) political make-up in each case; (2) if he will list the 100 constituencies with the greatest fall in electorate over the last three years by
(a) percentage and (b) total number. 
The information requested falls within the responsibility of the National Statistician. I have asked him to reply.
Letter from John Pullinger to Chris Ruane, dated 12 June 2003:
The National Statistician has been asked to reply to your recent questions concerning the 100 constituencies and wards with the greatest fall in electorate over the last three years. I am replying in his absence. (118903, 118904)
I am placing in the House of Commons Library a table showing the percentage change and total number change of the 100 parliamentary constituencies with the greatest fall in electorate over the period 16 February 1999 to 1 December 2002. The Office for National Statistics (ONS) did not publish electoral data for parliamentary constituencies as at 16 February 2000 and this is why figures for 1999 have been used.
ONS does not produce electoral statistics on ward boundaries. The lowest geography at which electoral statistics are published is parliamentary constituencies. Electoral statistics on ward boundaries are only available from each individual local authority.
