More than 60 percent of families in cities in Sichuan Province are moderately well-off - a standard of living known as xiaokang - but more should be done to help those on lower incomes, a survey by the National Bureau of Statistics (NBS) showed over the weekend.

The survey recorded the per capita annual disposable incomes of 24,000 city-based households.

Of those, 61.7 percent were found to have incomes of between 15,000 yuan ($2,000) and 60,000 yuan, which the surveyors said had attained the xiaokang standard.
