The Chamber Of Commerce of Milan has produced economic connections since 1811, focusing on the area of Milan. Since 1910, with the birth of the modern register for the companies, the Chamber has been given an accurate map of the productive system of the district. By unifying these data to those coming from other institutes and bodies, a statistic compendium of the area of Milan was formed. It represents a complete synthesis of information on physical, economic and social structure of the district of Milan, a product written for economic operators and institutions use.
