A movement along the demand curve for some goods is caused by a change in the price of that particular good. When the price of a good changes, it directly affects the quantity of that good that consumers are willing and able to buy. If the price of a good decreases, consumers will typically demand more of it, whereas if the price of a good increases, consumers will typically demand less of it. Changes in consumer income, tastes, the price of other goods, and population can also affect the demand for a good, but they do not cause a movement along the demand curve. Instead, they cause a shift in the demand curve itself, which represents a change in the amount of a good that consumers are willing and able to buy at any given price level.
