Because the most basic consumption of college students is in the canteen, Engel coefficient is the proportion of total food expenditure to total personal consumption expenditure. But first of all, it should be explained that most college students have no other income except family supply, so they will not spend a lot of money except basic living needs, so it is normal for Engel coefficient to be higher than that of ordinary urban and rural residents.

Prices in third-and fourth-tier cities are naturally lower than those in first-tier cities, and there is not much money spent elsewhere, so the overall cost is not too high. The influence of the region and its own situation on the cost is not small, but it is still necessary to analyze the specific situation. Of course, we should adhere to the fine tradition of thrift, and don't hesitate to spend what we shouldn't.
