Lazio (Latium) is a NUTS-1 region of west central Italy, bordered by Tuscany, Umbria, and Marche to the north, Abruzzo and Molise to the east, Campania to the south, and the Tyrrhenian Sea to the west. It is the region of Rome, capital of Italy.The population density ranges from 765 inhabitants per km2 in the province of Rome to less than 60 inhabitants per km2 in the province of Rieti (2008 est.). The overall population density in the region of Lazio is of 326 inhabitants per km2, which is the third highest amongst the Italian regions after Campania and Lombardia.
The best performing sectors are the aerospace industry, biomedicine, pharmaceuticals and biotechnology, tourism, shipbuilding and the audiovisual and media industry.Agriculture, crafts, animal husbandry and fishery are the main traditional sources of income. Industrial development in Lazio is limited to the areas south of Rome. Firms are often small to medium in size and operate in the building and building materials (Rome, Civitavecchia), paper (Sora), petrochemical (Gaeta, Rome), textile (Frosinone), engineering (Rieti, Anagni), automobile (Cassino), electronic and electro technical (Viterbo) sectors.Approximately 73% of the working population are employed in the services sector; this is a considerable proportion, but is justified by the presence of Rome, which is the core of public administration, banking, tourism and insurance.
