Shift of the Demand Curve

 

If something other than the price of the product changes, the whole curve will move to the right or to the left. This is known as a SHIFT of the demand curve.

 

In this case, the price of the product does not change, but something else changes

 

 

 

 

If more is demanded at each price, the demand curve shifts to the right

 

If less is demanded at each price, the demand curve shifts to the left
