For over 25 years the MRS Census and GeoDems Group (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.

On the sections above you will find details about upcoming events, resources and consultation responses available to download.

MRS CGG run the GeoDems Knowledge Base (GKB) which is a major database of geodemographic and other geodems sources. It provides a gateway into a comprehensive directory of several hundred selected websites covering the UK, Europe and many other parts of the world. Each site is checked and curated by members of the CGG and new contributions are encouraged from all users.

The GKB includes sections specifically devoted to areas of interest to the CGG. These include the CensusEurope (with links to all the national statistics agencies), Open Data and Real Time Geodemographics (the tracking of people and things on the move). New sections are added from time to time to reflect important developments in geodemographics.

How to get involved

The group encourage involvement, whether that be joining the LinkedIn network group, subscribing to bulletins via your MyMRS online account and managing your email preferences or joining the Census and GeoDems Group itself . Please also follow the group's twitter account: @MRS_CGG

Census Evaluation Workshop

On 8th January 2015, the ONS held an Outputs Evaluation workshop to collect feedback from users on the 2011 Census.

GKB

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.

Harmonisation is concerned with the use of standard definitions, concepts, questions and outputs. CGG have compiled a short guide on harmonisation, which gives information on standards available

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

Real Time Geodemographics is the study of people (or things) according to their spatial location through time. The GKB provides information on, and links to, websites about Real Time Geodemographics.

A guide to the 2001 Census

A guide to the 2001 Census.
