Like the consumer price index (CPI), the GDP deflator is a measure of price inflation/deflation with respect to a specific base year; the GDP deflator of the base year itself is equal to 100. Unlike the CPI, the GDP deflator is not based on a fixed basket of goods and services; the "basket" for the GDP deflator is allowed to change from year to ...
A CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. Sub-indices and sub-sub-indices can be computed for different categories and sub-categories of goods and services, which are combined to produce the overall index with weights reflecting their shares in the total of the consumer expenditures covered by the ...

The consumer price index (CPI), the personal consumption expenditures price index (PCEPI) and the GDP deflator are some examples of broad price indices.

[3] Market performance indices include the labour market index/job index and proprietary stock market index investment instruments offered by brokerage houses. Some indices display market variations.
A price index (plural: "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time.
Unweighted, or "elementary", price indices only compare prices of a single type of good between two periods. They do not make any use of quantities or expenditure weights. They are called "elementary" because they are often used at the lower levels of aggregation for more comprehensive price indices. [2]
It is the measure of the price level for some quantity. A deflator serves as a price index in which the effects of inflation are nulled. [1] [2] [3] It is the difference between real and nominal GDP.
