Book excerpt: The Connecticut Economic Information System (CEIS) is a central source of economic and demographic data about the state, its towns and its regions. It is maintained by the Connecticut Department of Economic and Community Development's research division. Types of data available through CEIS include employment and labor force statistics for Connecticut, substate areas, and towns, updated on a monthly basis; demographic and social statistics from the 1990 census of population and housing; statistics on the level of exports from Connecticut to other countries, and what industries those exports are concentrated in; measures of the growth of the national and state economies; profiles of towns and other areas, containing the most used and informative statistics about each town in a concise summary; and economic indicators showing the most recent information about the state's production, construction, consumption, and revenue collection, gathered from all participating state agencies.
