As a result of the profound economic and social changes brought about by postwar industrialization, including low birth rates, an aging population and thus a shrinking workforce, during the 1980s Italy became to attract rising flows of foreign immigrants. The present-day figure of about 5 million foreign residents, that make up some 8% of the total population, include 97,000 children born in Italy to foreign nationals (14% of total births in Italy) in 2014, but exclude foreign nationals who have subsequently acquired Italian nationality; this applied to 106,000 people in 2014. The official figures also exclude illegal immigrants, the so-called "clandestini", whose numbers are very difficult to determine. In May 2008 "The Boston Globe" quoted an estimate of 670,000 for this group. Since the fall of the Berlin Wall in 1989, and more recently, the 2004 and 2007 enlargements of the European Union, the main waves of migration came from the former socialist countries of Eastern Europe (especially Romania, Albania, Ukraine and Poland). The second most important area of immigration to Italy has always been the 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 the Far East (notably, China and the Philippines) and Latin America (Ecuador, Peru) have been recorded. Currently, there are 1.2 million Romanian-born citizens living and working in Italy. Today the Romanians make up the largest community in the country, followed by Albanians (441,027) and Moroccans (422,980). The fourth largest community in Italy are the Chinese. The majority of Chinese living in Italy came from the city of Wenzhou in the province of Zhejiang. Currently the foreign-born population of Italy was from: Europe (54%), Africa (22%), Asia (16%), the Americas (8%) and Oceania (0.06%). The distribution of immigrants is largely uneven in Italy: 84.9% of immigrants live in the northern and central parts of the country (the most economically developed areas), while only 15.1% live in the southern half of the peninsula.
