are notable in the business sector. The labour market is characterized by high seasonality, due to climatic hazards. Traditionally, the inhabitants suspended all outdoor activities (construction, agriculture, etc.) between December and April. In 1999 the unemployment rate was 12.8%, and a third of the employed worked in the public sector. The employment situation was worsened by the complete cessation of deep-sea fishing, the traditional occupation of the islanders, as the unemployment rate in 1990 was lower at 9.5%. The unemployment for 2010 shows a decrease from 2009, from 7.7% to 7.1%. Exports are very low (5.1% of GDP) while imports are significant (49.1% of GDP). About 70% of the islands' supplies are imported from Canada or from other parts of France via Nova Scotia. The euro is the currency in Saint Pierre and Miquelon. The Canadian dollar is also widely accepted and used. The "Institut d'émission des départements d'outre-mer" (IEDOM), the French public institution responsible for issuing currency in the overseas territories that use the euro on behalf of the Bank of France, has had an agency in Saint Pierre since 1978. The islands have issued their own stamps from 1885 to the present, except for a period between 1 April 1978 and 3 February 1986 when French stamps not specific to Saint Pierre and Miquelon were used. Demographics The total population of the islands at the March 2016 census was 6,008, of which 5,412 lived in Saint-Pierre and 596 in Miquelon-Langlade. At the time of the 1999 census, 76% of the population was born on the archipelago, while 16.1% were born in metropolitan France, a sharp increase from the 10.2% in 1990. In the same census, less than 1% of the population reported being a foreign national. The archipelago has a high emigration rate, especially among young adults, who often leave for their studies without returning afterwards. Even at the time of the great prosperity of the cod fishery, the population growth had always been constrained by the geographic remoteness, harsh climate and infertile soils. Ethnography Ruins show that Indigenous American people visited the archipelago on fishing and hunting expeditions before it was colonized by Europeans. The current population is the result of inflows of settlers from the French ports, mostly Normans, Basques, Bretons and Saintongeais, and also from the historic area of Acadia in Canada (Gaspé Peninsula, parts of New Brunswick, Prince Edward Island and Cape Breton) as
