Engel coefficient - Engel coefficient

Japanese: エンゲル係数 - エンゲルけいすう

The percentage of food expenses in a household's total consumption expenditure. The fact that this ratio generally increases with lower income levels is called Engel's Law, and was discovered by German statistician CLE Engel (1821-1896). He discussed it in his 1857 paper "Production and Consumption in the Kingdom of Saxony" and other publications. This coefficient is considered one measure of living standards, but is not necessarily useful for comparing social groups with different social security systems, price systems, or lifestyles. → Schwabe's Law → Related topics Household finances | Minimum living expenses

家計の総消費支出に占める食費の割合を百分比で表したもの。この割合が一般に低所得層ほど大となることをエンゲル法則といい，ドイツの統計学者エンゲルC.L.E.Engel〔1821-1896〕が発見。1857年の論文〈ザクセン王国における生産および消費事情〉ほかで論じた。この係数は生活水準測定の一基準とされるが，社会保障のあり方や価格体系，生活慣習の異なる社会集団の比較には必ずしも役だたない。→シュワーベの法則
