Even today there are still large concentrations of San Marino citizens residing in foreign countries, above all, in the United States, in France and in Argentina. There are more than 15,000 San Marino citizens spread throughout the world. An important turning-point in the political and social life of the country took place on March 25, 1906, when the Arengo met; out of 1,477 heads of family, 805 were present. Each head of family received a ballot which contained two questions: the first asking if the Government of San Marino should be headed by a Principal and Sovereign Council, and the second, if the number of members of the Council should be proportionate between the city population and the rural population.
