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]
Core CPI (blue) is less volatile than the full CPI-U (red), shown here as the annual percentage change, 1983–2021. A Core CPI index is a CPI that excludes goods with high price volatility, typically food and energy, so as to gauge a more underlying, widespread, or fundamental inflation that affects broader sets of items. More specifically ...
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.
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 ...
If product A is purchased by most consumers, and similar product B goes on sale making it cheaper, consumers will naturally buy what is cheaper. Substitution bias can cause inflation rates to be over-estimated. Data collected for a price index, if from an earlier period, may poorly correspond to the prices and consumer-expenditure-shares going ...
