The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Caron Walker, dated March 2014
On behalf of the Director General for the Office for National Statistics, I have been asked to reply to your Parliamentary Question asking the Secretary of State for Work and Pensions how many (a) 18 year olds and (b) people under 25 have been out of work for over a year; and what the equivalent figures were in each of the last six years. 193505
Estimates of unemployment by age are derived from the Labour Force Survey (LFS). The table provides estimates for period 2008 to 2013 for the number of people aged 25 and under who have been unemployed for over 12 months. Due to the small sample size, it is not possible to provide estimates for 18 year olds.
As with any sample survey, estimates from LFS are subject to a margin of uncertainty. These are indicated by the guide to quality in the table.
|Number of unemployed people, by duration for select age groups, three months ending November each year, 2008 to 2013, United Kingdom, not seasonally adjusted|
|Aged 16 to 24 years|
|Unemployed all over 12 months (thousand)||As a percentage of all unemployed in age group (%)|
|Guide to Quality: The Coefficient of Variation (CV) indicates the quality of an estimate, the smaller the CV value the higher the quality. The true value is likely to lie within +/- twice the CV—for example, for an estimate of 200 with a CV of 5% we would expect the population total to be within the range 180-220. Key: * 0 ≤ CV <5%—Statistical Robustness: Estimates are considered precise ** 5 ≤ CV <10%—Statistical Robustness: Estimates are considered reasonably precise *** 10 ≤ CV <20%—Statistical Robustness: Estimates are considered acceptable **** CV ? 20%—Statistical Robustness: Estimates are considered too unreliable for practical purposes CV ≥ Coefficient of Variation Source: Labour Force Survey.|
