The Unrepresented Nations and Peoples Organization estimates the Greek minority at approximately 70,000 people. Other independent sources estimate that the number of Greeks in Northern Epirus is 117,000 (about 3.5% of the total population), a figure close to the estimate provided by "The World Factbook (2006)" (about 3%). But this number was 8% by the same agency a year before. The 2014 CIA World Factbook estimate put the Greek minority at 0.9%, which is based on the disputed 2011 census. A 2003 survey conducted by Greek scholars estimate the size of the Greek minority at around 60.000. The US State Department uses a 1.17% figure for Greeks in Albania. The total population of Northern Epirus is estimated to be around 577,000 (2002), with main ethnic groups being Albanians, Greeks and Vlachs. In addition an estimated of 189,000 ethnic Greeks who are Albanian citizens reside in Greece.
