Description of the error:

This revision arises from an error found in the computation of tenure for 2007 EHCS grossing and analysis purposes. 105 housing association cases were mistakenly coded as local authority for 2007/08.

This did not in itself lead to any significant undercount of RSL/overcount of LA tenants for '2007' published findings because the partly misclassified tenure variable was itself an input into the grossing process (in other words, the error resulted in a reduced number of RSL cases receiving a higher weighting than should have been the case, and vice versa on the LA side). However the correction of the tenure classification for 2007 has necessitated a revision of the 2007 grossing factors themselves (household and dwelling), and the revision of these factors impacts on all results.

In general the revision results show very small to negligible differences. As the differences have no material impact on patterns and trends in results or on conclusions from those results, current publications will not be revised, but the revision will be incorporated into the English Housing Survey 2008 Housing Stock Report, and any future publications citing 2007 data.

The tables below compare the 2007 published results with corrected ones to illustrate the impact of the data revision.
