China fact of the day

By 1978, Han constituted 42 percent of Xinjiang’s population, up from a mere 6 percent in 1949.  The flow was reversed in the reform era, as many Han who had been forcibly relocated to the province returned to China proper.  In 1990, the Han share of the population was down to 37.5 percent, and official estimates of the time projected a decline to 25.0 percent by 2030.
