联合国曾作出规定,把用于食物方面的支出与总消费支出的百分比,作为衡量一个国家富裕程度的重要标准,这就是恩格尔系数。 当个人或家庭生活在恩格尔系数大于59％以上时,则视为绝对贫困化;50％——59％之间,为勉强度日;40％—50％之间为小康生活水平;20％—40％之间为富裕生活水平,以下为最富裕生活水平。 The United Nations has made it a rule that the percentage of expenditures on food and total expenditures spent on food should be regarded as an important criterion for measuring the wealth of a country. This is the Engel’s Coefficient. When personal or family life is greater than 59% of the Engel’s coefficient, it is considered as absolute impoverishment; between 50% and 59% is barely satisfactory; 40% -50% is well-off; 20% 40% for the rich living standards, the following is the richest living standards.
