- An Engel curve is a graph which shows the relationship between demand for a good (on x-axis) and income level (on y-axis). If the slope of curve is positive, the good is a normal good but if it is negative, the good is an inferior good.

The Engel curve, named after the German statistician Ernst Engel (1821-96), is a relation between the demand for a good and the income of its buyers, the former depending on the latter. The Engel curve of an individual consumer can be obtained from his ICC.
In microeconomics, an Engel curve describes how household expenditure on a particular good or service varies with household income. [1][2] There are two varieties of Engel curves. Budget share Engel curves describe how the proportion of household income spent on a good varies with income.
Jun 8, 2019 · An Engel curve is a graph which shows the relationship between demand for a good (on x-axis) and income level (on y-axis). If the slope of curve is positive, the good is a normal good but if it is negative, the good is an inferior good. One of the determinants of demand is consumer income.
Mar 22, 2024 · An Engel curve illustrates the relationship between an individual’s income and their expenditure on a particular good, holding all other factors constant. Essentially, it shows how changes in income affect the demand for a product.

Engel's Law is an economic theory put forth in 1857 by Ernst Engel, a German statistician. It states that the percentage of income allocated for food purchases decreases as a household's income rises, while the percentage spent on other things (such as education and recreation) increases.
In the mid 19th century, Ernst Engel published a study based on the expenditures of Belgian families. He divided them into three groups: "on relief," "poor but independent," and "comfortable." He then broke down their expenditures for food, clothing, housing, education, recreation, and other spending categories. Engel found that the poorer the grou...
Engel's Law remains a fundamental principle of economics today and underlies many economic and social policies around the world, including anti-poverty programs. In the 20th and 21st centuries, expenditure categories have grown to include many things that weren't around in Engel's day (automobiles, health insurance, and mobile phones, for example),...
Suppose a family with an annual household income of $50,000 spends 25% of their income on food, or $12,500. If their income doubles to $100,000, it is unlikely that they will spend $25,000 (25%) on food, although they may spend somewhat more than they had been spending. As the late MIT economist Paul A. Samuelson points out in his widely used colle...
Engel's Law states that as a household's (or a nation's) income rises, the percentage of income spent on food decreases and the percentage spent on other goods and services increases. Developed in the mid-19th century by the German statistician Ernst Engel, it remains influential in economics and public policy today.
In this article we will discuss about the Engel curve and income elasticity of demand, explained with the help of diagrams. The Engel Curve for a good is a relation of functional dependence between the income of the buyers and the demand for the good.
Jan 1, 2018 · An Engel curve describes how a consumer’s purchases of a good like food varies as the consumer’s total resources such as income or total expenditures vary. Engel curves may also depend on demographic variables and other consumer characteristics.
