Demand reflects how individuals and groups navigate needs amid scarcity and opportunity cost. Although price is the main factor influencing quantity demanded, several non price factors also shape demand. Changes in consumer tastes, often driven by trends or technology can shift demand curves.

When the price of a good changes, holding other factors constant, there is a movement along the curve, expansion if the price falls, contraction if it rises. However, when other factors like incomes, preferences or prices of related goods change,
