From the article :

The threshold at which tax becomes payable was raised from 3,500 yuan ($503) to 5,000 yuan a month on October 1st. The finance ministry says the number of people liable for income tax should fall to 64m as a result.

Is the article correct that only 64M out of 1.1B people will pay income tax or did they miss an order of magnitude? Just trying to calibrate since only 64M people making ~>$750/month seems like a low number for China.
