SHANGHAI, April 9 (Xinhua) -- Senior citizens account for more than 20 percent of the population of Shanghai, an economic powerhouse in eastern China, a city official said Thursday.

    Gao Julan, deputy head of the municipal civil affairs bureau, said that as of the end of 2008, there were more than 3 million registered citizens aged above 60 in Shanghai, or 21.6 percent of the population.

    The proportion was 4.8 percentage points higher than a year earlier.
