Shift in demand

From Conservapedia

Shift in demand is a term of Economics describing change in the location or shape of the demand curve. The shift is due to a change in something other than price, because a change in price simply causes a movement along the curve. A shift in demand may result in a different quantity demanded at a given price.

Examples of factors that could cause a shift in demand are a change in the price of a substitute or complementary good, a change in preferences, or a change in income or wealth.
