Supply and Demand Terminology

What is the difference between a change in demand and a change in the quantity demanded? The terminology can be confusing — but we’ll provide some clarity in this video. In short, a change in demand refers to a shift in the demand curve — caused by a number of factors such as income, population, etc. A change in quantity demanded refers to a movement along a fixed demand curve — caused by a change in price.
