Notes: Standard deviations in brackets. All consumption figures are in grams per capita. Calorie share is the percent of total calories attributable to the particular food category. Income and expenditure per capita are in 2006 yuan (Rmb). 1 jin = 500g. The only pair-wise difference that is statistically significant (at the 10 percent level) is meat per capita consumption in Hunan for the 0.3yuan/jin versus 0.2yuan/jin groups.
