- Shift in demand

- Not to be confused with: Movement along the demand curve
- A movement along the demand curve is the change in quantity demanded caused by a change in the good's own price.

What is the difference between shift in demand and movement along the demand curve?
A shift moves the whole curve because a condition of demand changed; a movement is a new point on the same curve because the good's own price changed.
