Sexual identity estimates were previously produced from the Integrated Household Survey (IHS), the IHS questions were removed from the Living Costs and Food Survey in 2014. The IHS variables (including sexual identity) were added to the Annual Population Survey (APS) in 2014 but they were still subject to IHS methodologies. The IHS variables were fully integrated into the APS in 2015 and are now subject to APS methodologies. A consistent back series from 2012 and a comparison of the estimates produced from the IHS and the APS are available.
