Demand can be classified as elastic, inelastic or unitary. An elastic demand is one in which the change in quantity demanded due to a change in price is large. An inelastic demand is one in which the change in quantity demanded due to a change in price is small. This is taken from a website at www.agmrc.org.
Conversely, inelastic demand means consumers will typically not be very responsive to changes in price. If there are more substitutes, a person will have more elastic demand. A good like gasoline has very few substitutes unless you own an electric car, so the demand for it will remain high even if the price skyrockets.
