95% C.I.: 95% confidence interval, the range within which we are 95% confident that the true value lies in the absence of bias.
See section 2.8 and Appendix 3.2 in the 'Self-reported work-related illness in 2004/05' (SWI04/05) report for more details on incidence estimates and rates.
The estimates in this table are based on self-reported work-related illness from the Labour Force Surveys in 2001/02, 2003/04, 2004/05 and 2005/06 and take account of revisions made to the Great Britain population estimates following the 2001 Census.
