What is the definition of market demand?

Market demand refers to the overall quantity demanded for a good or service by all consumers in a particular market at various price levels. This concept aggregates the individual demands of all consumers, highlighting how total demand for a product changes as its price varies. Market demand is typically represented by the market demand curve, which illustrates the relationship between the price of the good and the total quantity demanded. Understanding market demand is crucial for producers and policymakers alike, as it helps in forecasting sales and making informed decisions about resource allocation, pricing strategies, and market entry or exit.
