Claimant Count denominators for local authorities, counties, LEPS, regions and countries were updated on 16 September 2015 for all areas in the UK for 2014, based on the latest mid-year population estimates. Denominators for Westminster Parliamentary Constituencies in Northern Ireland have also been updated for 2014 as well as minor revisions to 2013 denominators for some local authorities.

The 2014 denominators will be carried forward for 2015 until updated estimates are released.

Denominators for Westminster Parliamentary Constituencies in Great Britain will be updated as soon as practical after the 2014 mid-year small area population estimates are published by ONS.
