Numerator:
Numerator data - Estimated number of GP and resident relevant male and female population based on GP lists in
the 2010 Attribution Data Set (ADS) and constrained to Office for National Statistics (ONS) 2009 mid-year
estimates (excluding special populations).
Source of numerator data - The NHS Information Centre for health and social care (IC).
Comments on numerator data - GP patient registration data were extracted from Family Health Services (FHS)
registers at postcode level in April 2010 or re-assigned to the postcode geography of the respective GP list.
Special populations i.e. armed forces, dependents of foreign armed forces, and convicted prisoners who have
been inmates for 6 months or more are not included.
Denominator:
Denominator data - Not applicable.
Source of denominator data - Not applicable.
Comments on denominator data - Not applicable.
Statistical methods:
All data have been adjusted to be consistent with population estimates published by ONS and then special
populations removed - the figures bear no resemblance to actual people. Therefore no figures have been
suppressed, and the spreadsheet may contain figures of 1. This does not imply that there is one person in that
Primary Care Organisation (PCO) in that age band, nor should it be taken to suggest that the figures are accurate
to this level. Their accuracy will be limited by the combined accuracy of: the ONS mid-year estimates, FHS
registers and GP practice registers, and the postcode to NHS organisation translations in the NHS Postcode
Directory.
For more information on methodology, see Annex 10.
Interpretation of indicators:
Quality of indicator - Annex 12 describes the criteria that should be used to judge the quality of this indicator. The
application of the criteria is dependent on the context (e.g. describing a single organisation, comparing several
organisations) and the level (e.g. national / regional with large numbers of events, local with small numbers of
events) at which the data are to be used.
