Explain the relationship between individual and market demand

Market demand can differet from individual demand. This is, however, often not the case. Groups of individuals usually have a demand for a certain product which in turn cretes what we call market demand. Market demand is simply the demand for a product from a large number of people; the market. And a large number of people is of course composed of individuals. This means that you may be an individual who created the market demand for certain products, but you don't create it for other products.
