In the middle of the second decade of the new century, more than 210 million people were living in western Asia (Afghanistan, Iran), central Asia (Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan) and the Caucasus (Azerbaijan, Armenia, Georgia, Russia). The level of population is low in some of these countries, for instance Armenia with fewer than three million inhabitants, but average in others, such as Uzbekistan and Afghanistan, each with a little more than thirty million. Iran is the country with the largest population in this zone: more than eighty million.
A population of more than 200 million but an average density
From the Altai Mountains to the Black Sea, from the plain of western Siberia to the coast of the Indian Ocean, the geographical zone of western and central Asia and the Caucasus covers 6,730,000 km². There are 31 inhabitants/km². Compared with densities worldwide, this region is relatively sparsely populated; and compared with the demographic giants of eastern and southern Asia, it might seem empty. China’s and India’s populations are more than 1,395 and 1,342 million respectively, with densities of nearly 150 and 400 inhabitants/km².
