The most commonly used indices are the CPI-U and the CPI-W, though many alternative versions exist for different uses. For example, the CPI-U is the most popularly cited measure of consumer inflation in the United States, while the CPI-W is used to index Social Security benefit payments.
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 ...
For example, the elderly consume roughly double the medical care of all urban consumers (studied for CPI-U and C-CPI-U) and urban wage earners and clerical workers (for CPI-W); inflation in medical care has exceeded that in much of the rest of the economy. To adjust for this, the BLS computes a consumer price index for the elderly (CPI-E). [16]
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), covers approximately 29 percent of the U.S. population. This index is used predominantly for adjusting Social Security ...
Chained dollars, also known as "chained consumer price index" or "chained CPI," is a measure of inflation that takes into account changes in consumer behavior in response to changes in prices. It is used to adjust certain economic variables, such as tax brackets and Social Security payments, for inflation.
Nominal GDP in a particular period reflects prices that were current at the time, whereas real GDP compensates for inflation. Price indices and the U.S. National Income and Product Accounts are constructed from bundles of commodities and their respective prices. In the case of GDP, a suitable price index is the GDP price index.
In statistics, economics,and finance, an index is a statistical measure of change in a representative group of individual data points. These data may be derived from any number of sources, including company performance, prices, productivity, and employment. Economic indices track economic health from different perspectives.
It was inadequate for that purpose. In particular, if the price of any of the constituents were to fall to zero, the whole index would fall to zero. That is an extreme case; in general the formula will understate the total cost of a basket of goods (or of any subset of that basket) unless their prices all change at the same rate.
