Passage: In 2016, Italy had about 5.05 million foreign residents, making up 8.3% of the total population. The figures include more than half a million children born in Italy to foreign nationals – second generation immigrants, but exclude foreign nationals who have subsequently acquired Italian citizenship; In 2016, about 201,000 people acquired Italian citizenship (130,000 in 2014). The official figures also exclude illegal immigrants, that were estimated in 2008 to number at least 670,000.Starting from the early 1980s, until then a linguistically and culturally homogeneous society, Italy begun to attract substantial flows of foreign immigrants. After the fall of the Berlin Wall and, more recently, the 2004 and 2007 enlargements of the European Union, large waves of migration originated from the former socialist countries of Eastern Europe (especially Romania, Albania, Ukraine and Poland). An equally important source of immigration is neighbouring North Africa (in particular, Morocco, Egypt and Tunisia), with soaring arrivals as a consequence of the Arab Spring. Furthermore, in recent years, growing migration fluxes from Asia-Pacific (notably China and the Philippines) and Latin America have been recorded.
