How many people changed their nationality?

The previous official figure was about 654.38 million+900,000 per year (only in Chinese mainland).

But this figure is moisture, because a large number of people are not within this statistical caliber. In fact, if we look at the number of people from European and American countries who come to China, they generally account for more than 50% of Chinese people. So in 20 14, a centralized clean-up was carried out, and the household registration and nationality of10.5 million people who had obtained foreign nationality were cancelled at one time.

To sum up, a reasonable estimate is that 400,000 people give up their China citizenship every year.
