This experimental series counts the number of people claiming Jobseeker's Allowance plus those who claim Universal Credit who are out of work and replaces the number of people claiming Jobseeker's Allowance as the headline indicator of the number of people claiming benefits principally for the reason of being unemployed. From May 2013 onwards these figures are not designated as National Statistics. Data prior to 2013 are counts of all persons claiming unemployment-related benefits i.e. Jobseeker’s Allowance . The constituency area boundaries used in the data are those defined by the Parliamentary Constituencies 2010 revision.
