Procida inhabitants live at the northeastern end of the island, in small houses overlooking the sea, with exotic bright colours; superb vineyards and citrus groves dotted with white buildings appear on the edge of this picturesque group of houses. The city centre is inhabited mostly by sailors; countryside is mainly cultivated with vineyards that give very popular wines; also the crops of citrus, fruits and potatoes are widespread. The marine activities, even though in decline, remains one of the largest sectors of employment, with people of different ages employed on merchant ships of the biggest shipping companies around the world, continuing a centuries-old tradition. Next to the navy, in recent years the habitants have tried to encourage the development of the tourist industry, and although in this area the results have been encouraging, they were lower than expected, due to the absence of a strong entrepreneurial tradition, as well as the lack of accommodation. Marginal part of the working population is engaged in commercial fishing with a decent fishing fleet, while even less people are devoted to the shipbuilding industry or agriculture. A limited industrial activity shall be added to fishing and agriculture (shipbuilding and preparation of hair silk fishing, obtained by silkworms and exported abroad).
