Tibet is one of the least densely populated regions in China.
Explanation:
China is one of the biggest countries in the world, and it is also the most populated country in the world. Despite having more than 1.3 billion people, China's population tends to be concentrated in certain parts of the country, while others have very low population density. In general, the eastern parts of the country tend to be the most populated, while the northern and western tend to be the least populated.
Some of the least populated regions in China are:
- Tibet
- Xinjiang
- Qinghai
- Inner Mongolia
Tibet is one of the four regions in China that has population density of below 50 people per square km. The basic reason for this is the geography of this region. It is a very high region, connected with the Himalayas, with very little arable land, and very harsh climate. Naturally, the people have avoided this region, as apart from having harsh conditions, it is also not a region that can support large population.
