今天我学到了一个新知识——“恩格尔系数”。我大概知道了“恩格尔系数”是食品支出总额占消费支出总额的比。联合国根据“恩格尔系数”的大小,对世界各国的生话水平制订了一个划分标准,即一个国家平均家庭恩格尔系数大于60%为贫穷;50%~60%为温饱;40%~50%为小康;30%~40%为相对富裕;20%~30%为富裕;20%以下为极其富裕。 Today I learned a new knowledge - “Engel Coefficient ”. I probably know that the “Engel’s Coefficient” is the ratio of total food expenditure to total consumption expenditure. According to the “Engel’s Coefficient”, the United Nations has formulated a division standard for the living standards of all countries in the world. That is, the average Engel’s coefficient of a country is greater than 60% for poverty, 50% -60% for food and clothing, 40-50% 30% to 40% for the relative wealthy; 20% to 30% for the rich; 20% for the most affluent.
