The per capita income of China's urban residents rose 8.4 percent, after deducting inflation, to 21,810 yuan (3,434 U.S.dollars) in 2011 from a year earlier, the National Bureau of Statistics (NBS) said at a press conference Tuesday.

Meanwhile, the per capita income of rural residents grew by 11.4 percent year-on-year to 6,977 yuan, faster than the previous year, according to Ma Jiantang, director of the NBS.

China's consumer price index rose 5.4 percent from the previous year, well above the government's full-year control target of 4 percent, according to the NBS last week.

The population of migrant workers last year reached 252.78 million, an increase of 4.4 percent, or 10.55 million from the 2010 level, said Ma.
