The data tables contain prevalence estimates of:

  • opiate and/or crack cocaine users, organised into age groups
  • opiate users, organised by age and gender
  • crack cocaine users

The tables also contain estimates at local authority, regional and national levels for 15 to 64 year olds. They can be used by local authority commissioners to help to plan services to tackle opiate and crack cocaine dependence .

The ‘Estimates of the prevalence of opiate use and/or crack cocaine use, 2014 to 2015’ published by the Liverpool John Moores University (LJMU) includes the methods used to get to the estimates, along with comparisons to previous estimates. The report compares estimates from 2014 to 2015 with estimates from 2011 to 2012.

LJMU has also published national and regional ‘Estimates of the number of children who live with opiate users, England 2014 to 2015’. The paper includes definitions and the methods used to get to the estimates.
