POLAR4 data

This page contains all the available resources for our third update to the classification of small areas across the UK, known as ‘POLAR4’.

Please note: The postcodes that were unclassified under POLAR3 have also had POLAR4 quintiles removed. We will shortly be analysing these postcodes in order to re-instate those that are safe for measurement.

POLAR4 classification files

The files contain header records describing the specification of the data they contain. The Middle Layer Super Output Areas (MSOA) data is presented in comma-separated variable (CSV) format. The POLAR4 postcode look-up file is also in CSV format but is zipped due to its large original size (approx. 31,000 KB).

(Note for those running Windows-based operating systems: the postcode to POLAR4 classification file will not open fully in Microsoft Excel. Either a specialist database or statistical software package is required [such as Microsoft Access, SPSS, SAS, S-plus, R]. Alternatively the file will open fully in Microsoft Wordpad.)
