The aim of the project was to understand the politics, economics and sociology of the membership and services of Chambers of Commerce. An important part of the analysis involved charting the financial structure of chambers, subscriptions, staff, committee structures, membership size, membership sector and corporate status, etc. Information has been constructed for 16 cross-sections, every 10-20 years, 1790-2005 for the United Kingdom and Ireland. The variables include the size of membership, membership by business sector and business type, finances of Chambers, staff numbers, major services provided, range of publications produced, committees, and codes for status in relation to government initiatives since the 1990s.
