^See （セルビア・クロアチア語）UN estimate, Kosovo’s population estimates range from 1.9 to 2.4 million. The last two population census conducted in 1981 and 1991 estimated Kosovo’s population at 1.6 and 1.9 million respectively, but the 1991 census probably under-counted Albanians. The latest estimate in 2001 by OSCE puts the number at 2.4 Million. The World Factbook gives an estimate of 1,804,838 persons living in Kosovo for the year 2009, 88% of thema are Albanians.
