Sujiatun, China

The population of 524,336 belies the harsh realities of living in Sujiatun. Bureaucracy is a persistent headache, with only 87 approved hospitals permitted to conduct organ transplants as of 2008 - a sharp drop from over 600 just a year prior. The organ transplant industry remains mired in allegations of unethical sourcing, with reports of organs being harvested from prisoners without consent. Sujiatun is not for the faint of heart.
