The purpose of consumer price indices is to provide a measure of change in prices of a fixed basket of products as determined in the Household Budget Survey.
Scope of the data
As to classification of the items surveyed, the prevailing criterion for the definition of the major groups is end use by households. The COICOP is a basis for classification, though it has not been applied comprehensively.
The prices collected are the cash prices paid in cash or by check, and refer only to the services and types of products described in the questionnaires, as well as those available at the point of purchase or in stock; services are those that can actually be rendered, and services and types of products generally available to the public.
Prices include taxes.
Discounts on the prices of goods are computed only if they apply to all consumers.
Price information is collected daily, with each establishment visited once a month.
