Demand reflects consumers' preferences and purchasing power at various price levels, indicating how much of a product they are ready to purchase within a given timeframe. It is influenced by factors such as price, income, and consumer tastes.

Consumer surplus is the amount a buyer is willing to pay minus the amount the buyer actually pays.
Producer surplus is the difference between the amount producers receive for a good or service and the minimum amount they would be willing to accept, reflecting their benefit from selling at a higher price.

The level of consumer surplus is shown by the area under the demand curve and above the ruling market price as illustrated in the diagram below:
