  Aggregation of individual demand to total, or market, demand - Wikipedia, the free encyclopedia
Each person's individual total utility gleaned from purchases depends on the size of his or her budget, but the distribution of wealth (and thus her budget) is a separate (free) variable in the aggregation.
Each person's demand curve is a function of his or her budget, so that if the distribution of wealth changes (by changing the distribution of prices and thus salaries, and so on), all of the individual demand curves change.
Markets cannot be claimed to select an optimum in the sense of the greatest total utility of society; indeed, there is not even general agreement on how total utility should be defined.

First, the framework builds individual demand for whatever services are offered from tastes for the underlying objects of consumer utility, the programming provided on those services.
The model of individual demand for cable services is then specified and the aggregation assumptions required to permit its estimation on a cross-section of market-level data are described.
