或者如果一个家庭少报了开支，他假设同一家庭同时也相应少报食物开支，这样恩格尔系数才不受影响。

Or if a household does underreport its spending, he assumes that it also downplays its food expenses proportionately, so that their Engel’s coefficient is unaffected.

比如在王晓鲁的调查中，最贫穷的人将收入中48%花费在食物上，而最富裕的仅为29%(恩格尔系数是0.29)。

In Mr Wang's survey, for example, the poorest people devoted 48% of their outlays to food, whereas the richest spent only 29% (an Engel's coefficient of 0.29).

如果人们少报了总开支，却对食物开支不隐瞒，这样恩格尔系数就人为的调高了。

If people underreported their overall spending, but told the truth about their food spending, their Engel's coefficients will be artificially high.
