UK Parliamentary Constituency Population Estimates (2011 Data Zone based)
Last update: 27 August 2020 Next update: August 2021
This section provides annual mid-year population estimates for the 59 UK Parliamentary Constituencies (UKPCs) in Scotland. The population estimates are available for each year from 2001 onwards for 2011 Data Zones, broken down by sex and single year of age.
Populations for UKPCs are based on data zone population estimates where each data zone has been assigned to a particular UKPC. Where a data zone crosses the boundary of two (or more) UKPCs it was assigned to the constituency containing the location of the population-weighted centroid of the data zone.
Work carried out using 2011 Census data suggested that UKPC population estimates based on 2011 Data Zones were within 2.5 per cent of the ‘true’ (that is Postcode based) population for 57 out of the 59 UK Parliamentary Constituencies. The estimates for the remaining two UKPCs (Glasgow North West and Glasgow North) have been adjusted to account for a boundary problem. The Evaluation of Non Standard Geography Population Estimates report on this website, gives further information on the data used in the quality assurance process.
