Data are extracted as a quarterly snapshot in time from the GP Payments system maintained by the Health and Social Care Information Centre (HSCIC). This release was extracted on 1 July 2014 so will be up to close of play on 30 June 2014. From April 2014, geographical references are taken from 2011 census information. At GP Practice, Clinical Commissioning Group, NHS England Area Team and NHS England Region levels, data are released in 5-year age bands which now finish at 95+, split by gender and aggregated. 
For the above reports, the data for GP Practices with 100 or fewer registered patients has been suppressed due to possible identification of individuals when data are linked to other data sets.
Data for GP practices at Lower Super Output Area (LSOA) level are provided by gender but not by age bands so no suppression is required. An additional machine readable version is provided in practice / LSOA /totals format. Further information on LSOA is available via the link below. NOTE: After publication it was found that the files for GP Practice, Clinical Commissioning Group, NHS England Area Team and NHS England Region showed data up to the upper age band of 85+ rather than 95+ as indicated above. This was revised the same day of publication.
