China's one-child policy is expected to be loosened in the coming years as experts recognize the implications of China's rapidly aging population. Some Chinese experts say five provinces will relax the policy in 2011, allowing two children for families where one spouse is an only child, and this may expand nationwide by 2013-2014. The one-child policy has accelerated labor shortages and distorted China's gender balance, with 119 boys born for every 100 girls last year. While the policy has been enforced through fines and forced abortions, gradual reform is seen as inevitable due to the economic and social costs of an aging workforce.
