Detailed explanation-1: -A change in demand means that the entire demand curve shifts either left or right. The initial demand curve D0 shifts to become either D1 or D2. This could be caused by a shift in tastes, changes in population, changes in income, prices of substitute or complement goods, or changes future expectations.

Detailed explanation-2: -A change in demand represents a shift in consumer desire to purchase a particular good or service, irrespective of a variation in its price. The change could be triggered by a shift in income levels, consumer tastes, or a different price being charged for a related product.

Detailed explanation-3: -A change in any one of the underlying factors that determine what quantity people are willing to buy at a given price will cause a shift in demand. Graphically, the new demand curve lies either to the right (an increase) or to the left (a decrease) of the original demand curve.

Detailed explanation-4: -Factors that can shift the demand curve for goods and services, causing a different quantity to be demanded at any given price, include changes in tastes, population, income, prices of substitute or complement goods, and expectations about future conditions and prices.

Detailed explanation-5: -The result will be a shift in the entire demand curve rather than a movement along the demand curve. A shift in a demand curve is called a change in demand. Suppose, for example, that something happens to increase the quantity of coffee demanded at each price.
