For over 25 years the CGG has been a leading independent voice in the geodemographics sector. Part of MRS, it exists to promote the full use of Census and geodemographic information. It works with the Office for National Statistics (ONS) and others to represent the needs of research.

How to get involved

The Geodemographics Knowledge Base (GKB)
 www.geodemographics.org.uk is an international online directory of carefully selected websites on geodemographic and geo-spatial analysis, socio-economic and demographic data sources. The site also includes articles of interest to those working in these areas and publishes an email bulletin.

The GKB Census page provides a gateway to the Census.

Social Grade

The ONS has produced census output on approximated social grade, by applying an algorithm developed by members of the MRS CGG – click here to find out more.

MRS and CGG consultation responses

The CGG advises MRS on matters relating to demographic, geographic and census information. Together, they have responded to a number of industry consultations – click here to read more.

Article: Under the Microscope by Robin Flowerdew and Barry Leventhal, based on an article in New Perspectives Magazine, September 1998. Despite their obvious success, no hard theory underlies today’s geodemographic classifications. Robin Flowerdew and Barry Leventhal put one of today’s products to the test and offer fuzzy geodemographics as a possible alternative. Read Under the Microscope

Marketing and geodemographics need high quality address information for sample frames, contacting customers, and geocoding data for analysis. Therefore, there was immediate interest when the government announced in early December 2010 a joint venture between Ordnance Survey and the Local Government Group – GeoPlace – to create a definitive national address gazetteer (NAG). However, it was also immediately apparent that access to NAG as proposed would be on a hybrid free to public sector (under the Public Sector Mapping Agreement) but charged to private sector basis. Also, that GeoPlace could gain an effective monopoly in address information, which, with continuing uncertainty about the future of the Postcode Address File (PAF), raised risks of lower quality and higher costs for private sector users. MRS decided to take steps to get a better deal.

Getting the best deal on address information
