Engel's Law
By Shivam Bhandari · Reviewed 31 October 2026 · How we write
what it means
As household income rises, the share spent on food falls — even though the absolute amount spent on food may rise.
How Engel's Law works
Poorer households spend a large share of income on essentials. As incomes grow, people spend more on services, education, health, travel, and discretionary goods.
For businesses, Engel's law is a map of where growth goes as a market gets richer — and why premium versions of essentials grow fast in rising-income economies.
where it comes from
German statistician Ernst Engel observed it in 1857 while studying the budgets of Belgian working-class families.

Fitness, tutoring, and travel businesses grow faster than basic grocery as cities get wealthier.
