Explanation:

Let me first try to define what demand and want are:

want: want is a desire for a product or service. It is said that wants are unlimited, however, the resources to actualize such wants are in a limited supply.

Demand: Demand is the quantity of good or service that a person is willing and able to pay for because of the availability of resources to do so, at a given price and time.

For a clearer understanding, demand can be seen as a subset of want that a consumer takes a further step to acquire, not just desire. There is a specific plan to acquire such wants.
