For example, World Bank survey data suggest that India’s per capita household expenditure has grown by only 1.5% annually since the early 1990’s, implying that the average Indian spent $720 in 2010. But national-income-accounts data show a 4.5% annual rise, on average, over the last two decades, translating into per capita expenditure of $1,673 in 2010 – roughly 2.5 times higher than the Bank’s estimate.
其次，世界银行不加鉴别地接受调查数据——即便它与其他来源的数据冲突。比如，世行调查数据表明印度人均家庭支出自20世纪90年代初以来的年增长率仅仅为1.5%，这意味着2010年印度人均支出为720美元。但国民收入账户数据表明过去二十年的平均年增长率为4.5%，即2010年人均支出为1673美元，比世行的估计高出2.5倍左右。
