Change in Demand vs. Change in Quantity Demanded
Change in demand is a shift of the demand curve, while change in quantity demanded is a movement along the demand curve.
A change in demand occurs when factors like income, preferences, or prices of related goods change, shifting the entire demand curve. A change in quantity demanded occurs when the price of the good itself changes, causing movement along the existing demand curve.
