The total value of private investable assets in China was more than 73 trillion yuan ($11.6 trillion) in 2012, up 14 percent year-on-year, the Boston Consulting Group said in a report on Thursday.

By the end of 2012, the number of Chinese high net worth households — those with investable assets of more than 6 million yuan — will reach 1.74 million, an increase of 17 percent from the same time last year. The growth, however, has been much slower than the 38 percent increase seen from 2009 to 2011, the report said.

High net worth households in China are still concentrated in the more economically developed southeast coastal region.

However, given the current economic situation, affluent cities and provinces, such as Beijing, Shanghai and Guangdong, have underperformed the national average growth of high net worth households.
