The Census Dissemination Unit (CDU) at MIMAS, based at the University of Manchester, is pleased to announce the release of a 2005 update of the dataset supplied by commercial geodemographics specialists Experian for academic use.
The dataset includes the Mosaic household classification, and is supplied for lower level super output areas (LSOAs) for the entire UK. The previous 2004 version of the dataset will continue to be available to users.
The dataset has three main components:
Mosaic UK household classification
Mosaic UK is a market-leading consumer segmentation product. It classifies all 24 million UK households into 11 groups, 61 types and 243 segments, and is updated annually.
Median Household Income
Experian has used a multi-stage process to create models that predict personal and household income. Using data from a number of surveys, including MORI's Financial Tracking Survey, models have been developed to predict personal income for a number of standard employment types. These were then accumulated to create household income based on the composition of the household.
Population Projections
Using methodologies developed in accordance with JICPOPs (Joint Industry Council for Population Standards), Experian have produced contemporary estimates, as well as five-year and ten-year projections of resident populations split by gender and age.
Access to the data is controlled by Athens authentication. Information about the Athens authentication system is available from the Census Registration Service website at http://census.data-archive.ac.uk.
