About 95 percent of migrant mothers in China had their children delivered in hospital in 2012, according to a report issued by the National Health and Family Planning Commission on Saturday.

The commission estimated that the number of married migrant women of child-bearing age topped 63 million in that year.

About 70 percent of migrant mothers chose to deliver their children in the place where they were working and living, the report said.

To help this most under-privileged group, China provides in-hospital delivery subsidies for rural women, a project that has made a significant contribution to reducing maternal deaths and neonatal tetanus.

According to China's official statistics, its migrant population hit 236 million in 2012, meaning there was one migrant citizen per six Chinese.

In recent years, the Chinese government has intensified its efforts to enhance its health services for the migrant population.
