In order to maintain a low birth rate despite the country's economic boom, authorities in China have stepped up surveillance on city's growing floating population of migrant workers who were found to have more children violating the one child policy norm.
The Chinese government will strengthen the surveillance of births among the floating population, especially migrant workers, who have created a headache for the government, who are trying to bring the city's population under control, 'Global Times' reported .
Statistics released by the Beijing Municipal Commission of Population and Family Planning showed that Beijing maintained a low birth rate in 2009, but births outnumbered those in previous years, with unplanned children among the floating population being one of the main causes.
In his work report early this month, Prime Minister, Wen Jiabao told the Peoples Congress that China, the most populous country in the world would continue to maintain low birth rate.
A large number of migrant workers living in suburban areas of Beijing keep "making contributions" to the growth in the population due to their deep-rooted "son preference" tradition.
