Price Inelastic Demand

Price inelastic demand refers to a situation where a change in the price of a good or service leads to a proportionally smaller change in the quantity demanded. In other words, consumers continue to buy nearly the same amount even if the price increases or decreases. This usually applies to necessities or goods with few substitutes.

In the UK, a good example is petrol. Even if fuel prices rise, many people still need to drive to work or school, so they continue purchasing petrol. Another example is electricity—households still need energy for heating and appliances, even when prices rise.

Price inelastic demand means businesses can increase prices without a significant drop in sales, and governments often tax these goods (e.g., fuel duty) to raise revenue. The degree of inelasticity depends on how essential the product is and whether alternatives are available.
