The above table illustrates two commonly discussed important differences between the PCE deflator and CPI-U. The first major difference is the relative importance of housing, which is due in part to the difference in scope mentioned above. CPI contains a large component of owner-equivalent rent, which by definition is an imputed value and not a ...
In practice, the difference between the deflator and a price index like the Consumer price index (CPI) is often relatively small. On the other hand, with governments in developed countries increasingly utilizing price indexes for everything from fiscal and monetary planning to payments to social program recipients, even small differences ...
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 ...
Consumer Price Index for Americans 62 years of age and older (R-CPI-E): This index re-weights prices from the CPI-U data to track spending for households with at least one consumer age 62 or older.
However, from December 1982 through December 2011, the all-items CPI-E rose at an annual average rate of 3.1 percent, compared with increases of 2.9 percent for both the CPI-U and CPI-W. [28] This suggests that the elderly have been losing purchasing power at the rate of roughly 0.2 (=3.1–2.9) percentage points per year.
In the past 60 years, the United States has experienced deflation only two times; in 2009 with the Great Recession and in 2015, when the CPI barely broke below 0% at −0.1%. [ 80 ] Some economists believe the United States may have experienced deflation as part of the financial crisis of 2007–2008 ; compare the theory of debt deflation .
The United States Consumer Price Index (CPI) is a price index that is based on the idea of a cost-of-living index. The U.S. Department of Labor's Bureau of Labor Statistics (BLS) explains the differences: The CPI frequently is called a cost-of-living index, but it differs in important ways from a complete cost-of-living measure.
It is a statistic designed to help to compare how these price relatives, taken as a whole, differ between time periods or geographical locations. Price indices have several potential uses. For particularly broad indices, the index can be said to measure the economy's general price level or cost of living .
