Demand

Demand is a fundamental concept in economics that describes a consumer's desire to purchase goods and services and their willingness to pay a certain price for them. It is quantified by the quantity of a good that consumers are willing to buy at different prices. Demand can be influenced by a number of factors, including the price of the good, consumer income, and preferences. Typically, there is an inverse relationship between the price of a good and the amount of it demanded, all else being equal, which is known as the law of demand.
