|Welcome to the Leeds Geodemographic Analysis System (LGAS), the new and enhanced web-based version of GB Profiles91!
LGAS is a small area profiling system designed to provide quick and easy access to more than 100 small area census classifications that have been developed in the Centre for Computational Geography, University of Leeds.
You can enter a single enumeration district (ED) or postcode or you can upload a file containing several EDs or postcodes to generate a profile report. You can also provide the system with additional attributes such as mailing response information to plot gains charts.
