As of 1 January 2017, there were 5,047,028 foreign nationals resident in Italy.
 This amounted to 8.2% of the country's population and represented an increase of 92,352 over the previous year.
 These figures include children born in Italy to foreign nationals (who were 75,067 in 2014; 14.9% of total births in Italy), but exclude foreign nationals who have subsequently acquired Italian nationality; this applied to 129,887 people in 2014.
 Around 6,2 million people residing in Italy have an immigration background (around the 10% of the country population).
 They also exclude illegal immigrants whose numbers are difficult to determine.
 In May 2008, "The Boston Globe" quoted an estimate of 670,000 for this group.
 The distribution of foreign born population is largely uneven in Italy: 59.5% of immigrants live in the northern part of the country (the most economically developed area), 25.4% in the central one, while only 15.1% live in the southern regions.
 The children born in Italy to foreign mothers were 102.000 in 2012, 99.000 in 2013 and 97.000 in 2014.
