What is the problem with price data collection?
The central problem of price-data collection is to gather a sample of prices representative of the various price quotations for each of the commodities under study. Sampling is almost always necessary. The larger and the more complex the universe of prices to be covered by the index, the more complex the sampling pattern will have to be. An index of prices paid by consumers in a large and geographically varied country, for example, ideally should be based on a sample representative of price changes in different cities and localities, in different types of outlets (supermarkets, department stores, neighbourhood shops, etc.), and for different commodities. The number of prices chosen to represent each type of city (or metropolitan area), type of outlet, and category of commodity would ideally be proportionate to its relative importance in the expenditures of the nation. Most price indexes are based on some approximation to such a sampling design.
