Edited sentence: According to the 2001 national census, Ibiza had 93,000 inhabitants (against 76,000 in 1991, 64,000 in 1981, 45,000 in 1971, and 38,000 in 1961).Demographically, Ibiza display a very peculiar configuration, as census agencies diverge on exact figures.However, two years later, this figure jumped to 108,000 (Govern de les Illes Balears - IBAE 2004).In decreasing order, foreigners are Germans, British, Latin Americans, Moroccans, French, Italians, Dutch, in addition to a myriad of other nationalities.In private correspondence, a state technician explained to me, ‘Considering that the Pitiusas have witnessed strong immigration in recent years, it has become difficult to know their exact population at any specific moment’.In terms of origin, about 55 per cent of island residents were born in Ibiza, 35 per cent are immigrants from mainland Spain (mostly working-class families from Andalusia, and the remainder from Catalonia, Valencia and Castilla), and the about remaining 10 to 15 per cent are foreign, dual and multi-national citizens of the EU and abroad (Govern de les Illes Balears - IBAE 1996).This discrepancy stems from the amnesty which incorporated a number of unregistered foreign migrants.This mosaic reflects the fluidity of foreigners living and moving across the island, in ways that render impossible to quantify the expatriate population (Rozenberg 1990)
