Tashkent is Uzbekistan’s biggest city and the Fergana Valley is home to Uzbekistan’s largest concentration of people, a quarter of the population.
About three-quarters of the population are ethnic Uzbek.
Samarkand, the second city, is Tajik-speaking, as are many of the communities surrounding it, including Bukhara and Karshi.
The further west you travel the more sparsely populated the land becomes.
Karakal pakstan, home to Kazakhs,Karakalpaks and Khorezmians, has seen its population dwindle as a result of the Aral Sea disaster.
Around 37% of Uzbeks live in cities, with the rest in rural farming towns and villages.
Independent Uzbekistan has never done a census (although one is scheduled for 2010), so updated demographic information is certainly hard to come by.
The population growth rate, which was 2.2% at the time of independence, had declined to 0.94% in 2009 according to the CIA World Factbook.
The emigration of tens of thousands of mostly Russian Slavs has something to do with that.
Ethnic Russians comprised almost 10% of the population in the late 1980s; by 1996 that number was down to 5.5%, and today it could be as low as 2%.
About 28% of the population is under 15 years of age.
A number of minority groups make up a tiny portion of the population, most notably Koreans and Russians in Tashkent.
There is still a miniscule Jewish population in Bukhara and an even smaller one in Samarkand.
