In economics, demand is the quantity of a good that consumers are willing and able to purchase at various prices during a given time.[1] The relationship between price and quantity demand is also called the demand curve. Demand for a specific item is a function of an item's perceived necessity, price, perceived quality, convenience, available alternatives, purchasers' disposable income and tastes, and many other options.
