NUMBER OF BUYERS: One of the five demand determinants assumed constant when a demand curve is constructed, and that shift the demand curve when they change. The other four are income, preferences, other prices, and buyers' expectations. This determinant is based on the simple observation that if more people are willing and able to buy a good, then demand is greater.
