Demand

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][2] In economics "demand" for a commodity is not the same thing as "desire" for it. It refers to both the desire to purchase and the ability to pay for a commodity.[2]

Demand is always expressed in relation to a particular price and a particular time period since demand is a flow concept. Flow is any variable which is expressed per unit of time. Demand thus does not refer to a single isolated purchase, but a continuous flow of purchases.[2]
