Yes, I agree with this statement.

• Nature of Commodity : By nature, commodities are classified as necessaries, comforts and luxuries. Normally demand for necessaries like food grains are relatively inelastic and for comforts and luxuries like diamond, perfumes, etc is relatively elastic.
• Availability of Substitutes : The larger the number of substitutes available for a commodity, the greater would be the elasticity. Demand for products like soap, soft drinks, detergents, tooth paste, etc. have many substitute so demand is elastic, ‘However, salt, garlic, onions have no substitute so demand is inelastic.
• Durability of the Commodity : The demand for durable goods like T.V., car, fridge, etc is relatively inelastic in the short run and elastic in the long run. Whereas the demand for perishable goods is relatively inelastic.
• Uses of Commodity : Single use commodities have less elastic demand and multi-use goods like coal, electricity, sugar, etc. have relatively elastic demand.
• Range of Price : The demand for commodities which are highly priced and will have a inelastic demand like AC, car, etc. Even very low priced goods have inelastic demand.
• Consumer’s Income : Generally if income is very high, the demand for over all commodities tends to be relatively inelastic. The demand pattern of the rich people is rarely affected even when there is significant price change.
