Résumé :
This report provides estimates of the prevalence of opiate and/or crack cocaine use at the Government Office Region and national level in England for 2009/10. It is a follow up to the four reports that provided prevalence estimates for 2004/05 (Hay et al. 2006), 2005/06 (Hay et al. 2007a), 2006/07 (Hay et al. 2008) and 2008/09 (2010). Estimates of the prevalence of opiate use, crack cocaine use and drug injecting (by users of opiates and/or crack cocaine) are also presented. Two prevalence estimation methods have been used; the capture-recapture method and the multiple indicator method.
The capture-recapture method examines the overlap between different sources of data on individual drug users that are available at the local level to estimate the size of the hidden drug using population at the DAT area level.
The multiple indicator method models the relationship between the capture-recapture estimates and readily available drug indicator data, such as numbers of drug offences in an area. It then applies that relationship to the areas where capture-recapture estimates are not available and provides estimates of drug use for those areas. The DAT area estimates are then summed to provide regional and national estimates.
