A study from the Mediterranean Migration Observatory maintains that the 2001 census recorded 762,191 persons residing in Greece without Greek citizenship, constituting around 7% of total population. Of the non-citizen residents, 48,560 were EU or European Free Trade Association nationals and 17,426 were Cypriots with privileged status. The majority come from Eastern European countries: Albania (56%), Bulgaria (5%) and Romania (3%), while migrants from the former Soviet Union (Georgia, Russia, Ukraine, Moldova, etc.) comprise 10% of the total. Some of the immigrants from Albania are from the Greek minority in Albania centred on the region of Northern Epirus. In addition the total Albanian national population which includes temporary migrants and undocumented persons is around 600,000.

In 2001, how many Greek residents were not citizens?
