The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Stephen Penneck, dated
Dear Lord Bradley,
As Director General for the Office for National Statistics, I have been asked to reply to your Question asking what percentage of employed people in each constituency in Greater Manchester work in (a) the public sector, (b) the private sector, and (c) the voluntary sector. [HL1781]
Individuals are classified to the public or private sector according to their responses to the APS. Consequently, the classification of an individual's sector may differ from how they would be classified in the national accounts. Estimates of persons working in the voluntary sector are not available from the APS.
Table 1 shows the number and percentage of persons employed in the public and private sectors in each constituency in Greater Manchester from the APS for the period July 2008 to June 2009. As with any sample survey, estimates from the APS are subject to a margin of uncertainty. A guide to the quality of the estimates is given in table 1.
National and local area estimates for many labour market statistics, including employment, unemployment and claimant count, are available on the NOMIS website at http://www.nomisweb.co.uk.

|1 Coefficients of Variation have been calculated as an indication of the quality of the estimates. See Guide to Quality below.|
Guide to Quality: The Coefficient of Variation (CV) indicates the quality of an estimate. The smaller the CV value, the higher the quality.
|Coefficient of Variation|
|Key||(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|
