Under the revised system the yearly averages for examination degrees awarded was about 21. The way in which the four regional racial categories were divided tended to favor the Mongols, Semu-ren, and North Chinese, despite the South Chinese being by far the largest portion of the population. The 1290 census figures record some 12,000,000 households (about 48% of the total Yuan population) for South China, versus 2,000,000 North Chinese households, and the populations of Mongols and Semu-ren were both less. While South China was technically allotted 75 candidates for each provincial exam, only 28 Han Chinese from South China were included among the 300 candidates, the rest of the South China slots (47) being occupied by resident Mongols or Semu-ren, although 47 "racial South Chinese" who were not residents of South China were approved as candidates.
