History: Central Asia, 140 Years Ago

Demographics
By a broad definition including Mongolia and Afghanistan, but excluding Pakistan, more than 90 million people live in Central Asia, about 2% of Asia's total population. Of the regions of Asia, only North Asia has fewer people. It has a population density of 9 people per km², vastly less than the 80.5 people per km² of the continent as a whole.
• Languages
Russian, as well as being spoken by around six million ethnic Russians and Ukrainians of Central Asia, is the defacto lingua franca throughout the former Soviet Central Asian Republics. Mandarin Chinese has an equally dominant presence in Inner Mongolia, Qinghai and Xinjiang.
