 The Department of Statistics of Georgia estimated Abkhazia's population to be approximately 179,000 in 2003, and 178,000 in 2005 (the last year when such estimates were published in Georgia).Encyclopædia Britannica estimates the population in 2007 at 180,000 and the International Crisis Group estimates Abkhazia's total population in 2006 to be between 157,000 and 190,000 (or between 180,000 and 220,000 as estimated by United Nations Development Program in 1998).The size of Abkhazia's population more than halved due to the 1992-1993 war – at the time of the 1989 census it had measured 525,061.
