In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): that is, changes in price have a relatively small effect on the quantity of the good demanded.
Inelastic Demand Curves. If the demand for an item changes proportionately less than the price changes, then the item is price inelastic. For example, a demand curve is inelastic if the price of an item increases by 1 percent and purchases decrease by half a percent. Demand curves for items that people need to survive, such as staple foods, are inelastic, because people will buy the items regardless of price.
