China, the world's most populous nation, is expected to have more than four million wealthy households by 2015, making it the world's fourth-largest country in terms of the number of wealthy families, trailing the US, Japan and Britain, a research report released by McKinsey & Company said.
The number of wealthy households whose annual income exceed 250,000 yuan ($36,574) living in urban areas topped 1.6 million last year, it said.
While the wealthy currently accounted for less than one per cent of urban Chinese households, the number is expected to grow at an annual rate of 15.9 per cent in next five to seven years, said the report.
The wealthy in China were concentrated in the country's more prosperous eastern and southern regions, with around 30 per cent of the wealthy families living in China's four largest metropolitans -- Beijing, eastern Shanghai, southern Guangzhou and Shenzhen, the official Xinhua news agency reported.
