5 DEMOGRAPHY AND DEMOGRAPHICS
5.1 Population Structure
5.1.1 Difference in GP Registered Population and Resident Population
Different population estimates are available from different sources. One source is the
2001 Census, which provides the number of residents for different geographical areas,
including for wards, local authorities and PCTs. This forms a baseline figure for
biannual projections completed by the Office for National Statistics (ONS). Another
population estimate source is from General Practitioner (GP) registrations 5 . The people
registered with GPs can then be either assigned to a geographical area based on their
postcode of residence or the postcode of their GP practice. In many cases, these are
the same, but not always particularly the smaller the geographical area. Residents of
East Riding of Yorkshire (ERoY) who live near Hull may be registered with General
Practices within Hull and vice versa. However, the local registration files contain
patients registered with GPs from both Hull and East Riding of Yorkshire (as well as
some in the immediately surrounding area), and therefore, the majority of Hull residents
who are registered with a GP will be included in this file. When people move address
and need to change their GP, there are often delays associated with this, particularly so
for the young who do not regularly attend a GP. However, it is hoped that the numbers
and characteristics of people who are down as registered with a local GP who have
moved away roughly balance with those people who are new to the area who have not
yet registered with a local GP. However, it is likely that the GP registration file
overestimates the population as there will be some individuals who have emigrated
abroad or moved to Scotland, and have not informed their GP (their records will not be
automatically updated).
The GP registration file is also important with regard to obtaining an estimate of the
registered population for Hull. Table 6 illustrates the difference between resident and
registered population using the GP registration file. In October 2010, there were
289,698 patients registered with Hull GPs and 265,257 Hull residents. Some postcodes
of practices or patients were missing and are included in the „outwith area‟ group.

5 Unless otherwise stated, most of the analyses in this document use (registered or resident) population
estimated from General Practitioner registrations (because it is available at individual patient level and this
format is required for the majority of the analyses).
