While Romania is both an origin and destination country for international migration, it remains primarily the former, with high net emigration. According to 2011 Census data provided by the National Statistical Institute, the number of Romanians residing abroad for more than 12 months was 727 000 persons while an additional 386 000 stayed abroad for less than one year. Thus, the 2011 Census data indicate a total stock of more than 1.1 million Romanian nationals abroad. However, the 2011 Census data is likely to underestimate emigration, as other estimates of the stock of Romanian emigration range as high as 3 million persons. Migration of Romanian nationals has been a source of concern for the national authorities, as the country loses young and skilled people. According to the 2011 Census data, the persons who left Romania for at least one year originated mainly from urban areas and 71% were aged between 20 and 44 years old. Most emigrants are from the Western counties (e.g. Sibiu, Timiş and Braşov). According to Census data, the main countries of residence for Romanian nationals abroad were Italy (511 000), Spain (242 000), Germany (62 000), United Kingdom (59 000) and France (45 000). Destination country figures are higher for Romanian emigration: Italy recorded more than one million Romanian residents, and Spain 918 000, at the end of 2012.
