I have been asked to reply.
The information requested falls within the responsibility of the UK Statistics Authority. I have asked the Authority to reply.
Letter from Colin Mowl, dated October 2008:
The National Statistician has been asked to reply to your Parliamentary Question asking what estimate has been made of the number of people who wish to work beyond retirement age in (a) Leeds West, (b) the Leeds City area and (c) Yorkshire and Humberside region in each year since 1997. I am replying in her absence. (228292)
The Office for National Statistics (ONS) compiles employment statistics for local areas from the Annual Population Survey (APS) and its predecessor the annual Labour Force Survey (LFS) following International Labour Organisation (ILO) definitions.
Estimates are provided for the number of people over statutory pension age (males aged 65 and over, females aged 60 and over) who stated they were available to work when surveyed. A respondent is classified as being available to work if they are unemployed and available to work, or employed.
Table 1, attached, shows the number of persons in employment and unemployment over statutory pension age in Leeds West, Leeds and the Yorkshire and the Humber region.
The estimates from 1998 to 2004 are for the 12 month period ending February that year and taken from the annual LFS. Figures for 2005 to 2008 are for the 12 month period ending March that year and taken 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. A guide to the quality of the estimates is given in Table 1.

See 4 as follows. 4 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.
