The information requested falls within the responsibility of the UK Statistics Authority. I have asked the Authority to reply.Letter from Karen Dunnell, November 2008:"'As National Statistician, I have been asked to reply to your Parliamentary Question about how many people were (a) employed (i) full-time (ii) part time and (b) unemployed in (A) City of York constituency, (B) City of York local authority area, (C) Yorkshire and The Humber and (D) the United Kingdom (1) at the latest date for which figures are available and (2) at the same date in each of the previous 10 years.""(237046)""The Office for National Statistics (ONS) compiles employment statistics for local areas from the annual Labour Force Survey (LFS) and the Annual Population Survey (APS) following International Labour Organisation (ILO) definitions.""Table 1, attached, shows the number of people aged 16 and over who were in full-time and part-time employment, and those people who were unemployed, in the City of York Parliamentary Constituency, York Unitary Authority, Yorkshire and The Humber and the UK. Estimates are provided for the 12 months ending in February from 1998 to 2004 from the annual LFS, and for the 12 months ending in March from 2005 to 2008, from the APS.""As these estimates are for a subset of the population in small geographical areas, they are based on small sample sizes, and are therefore subject to large margins of uncertainty."

The figures presented are weighted to population estimates published in 2007 ² Coefficients of Variation have been calculated for the latest period as an indication of the quality of the estimates. See Guide to Quality as follows: 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 per cent. we would expect the population total to be within the range 180-220. Key Coefficient of Variation (CV) (%) Statistical Robustness * 0 = CV< 5 Estimates are considered precise ** 5 = CV < 10 Estimates are considered reasonably precise *** 10 = CV < 20 Estimates are considered acceptable **** CV 20 Estimates are considered too unreliable for practical purposes Source: Annual Labour Force Survey/ Annual Population Survey
