… and other questions


This is a summary of population and related statistics for Cornwall from the 2011 census and other sources.

The ONS divides the country into several areas of differing sizes. The ones I look at here are output areas (OA), lower layer super output areas (LSOA), wards, and constituencies. In blogposts I have called the LSOAs subwards.

In Cornwall (excluding Scilly) there are 1792 OAs, 326 LSOAs, 123 unitary council wards, and (including Scilly) 6 parliamentary constituencies. The LSOAs and their census code numbers can be found by the interactive map here.

The average population of an OA is around 300 and of an LSOA 1500. Each has a distinctive 2011 census code number.

The census population of Cornwall (excluding Isles of Scilly)was 532 273. There were 230 389 households each with an average of 2.3 people. Cornwall comprised 354 619 hectares with an average population density of about 1.5 per hectare.

The PHP01 tables, giving the details of the census population statistics for the OAs, LSOAs, and wards, released 23 November 2012, are here. The constituency figures are mid-2011 estimates (released 30 May 2013) and are here.

Electoral register
The Office for national statistics (ONS) has published electoral register statistics. These are people aged 18 and over who are eligible to vote and thus exclude some foreign citizens for example; people who move away are removed from the register but this may not be instantaneous. They are up to date up to December 2014.

Cornwall local government electors: 416 264
Cornwall parliamentary electors: 413 311
(Parliamentary electors in Camborne and Redruth 65 157, North Cornwall 65 464, South East Cornwall 69 873, St Austell and Newquay 75 117, St Ives (including Isles of Scilly) 66 330, Truro and Falmouth 71 370.

Patients registered with GPs in Cornwall and Isles of Scilly (Kernow Clinical Commissioning Group)
Clinical commissioning group population 2012: 555 917

The number of GP patients in England has regularly exceeded the population every year since 1961. Reasons for excess population on GP lists are given here: some patients are registered with more than one practice, some have more than one NHS number, some patients remain on the list after they have died or moved abroad, and the effectiveness of the removal of ex-patients varies.
