The index number is then expressed as 100 times the ratio to the base value.

An index number is an economic data figure reflecting price or quantity compared with a standard or base value. The base usually equals 100 and the index number is usually expressed as 100 times the ratio to the base value. Index numbers measure changes in such magnitudes as prices, incomes, wages, production, employment, products, exports, imports, etc. By comparing the index numbers of these magnitudes for different periods, the government can know the present trend of economic activity and accordingly adopt price policy, foreign trade policy and general economic policies. In constructing an index number, the following steps should be noted: 1. Purpose of the Index Number: 2. Selection of Commodities: 3. Selection of Prices: 4. Selection of an Average: 5. Selection of Weights: 6. Selection of the Base Period: 7. Selection of Formula: An index number of prices is an index of the prices of goods and services bought by the household. An economy produces a large number of different products. The price change of each commodity is expressed typically in percentage terms and then the average of the price changes of these commodities is calculated.

In this section, we will consider an economic approach to the CPI that is based on the. plutocratic cost of living index that was originally defined by Prais (1959).
