There are also specialized measures, such as measures of interest rates.
How does a CPI sample work?
A particular item enters the CPI sample through a process called initiation. This initiation process, typically carried out in person by a CPI data collector, involves selecting a specific item to be priced from the category that has been designated to be priced at that store. For example, suppose a particular grocery store has an outlet where cheese will be priced. A particular type of cheese item will be chosen, with its likelihood of being selected roughly proportional to its popularity. If, for example, cheddar cheese in 8 oz. packages makes up 70 percent of the sales of cheese, and the same cheese in 6 oz. packages accounts for 10 percent of all cheese sales, and the same cheese in 12 oz. packages accounts for 20 percent of all cheese sales, then the 8 oz. package will be 7 times as likely to be chosen as the 6 oz. package. After probabilities are assigned, one type, brand, and container size of cheese is chosen by an objective selection process based on the theory of random sampling. The particular kind of cheese that is selected will continue to be priced each month in the same outlet.
How is the CPI sample selected?
The outlets in the CPI sample are selected using a point of purchase survey (POPS) where respondents are asked where they made purchases. To the extent respondents of that survey report making purchases from online outlets, those outlets have a chance of being selected for the sample. As of 2017, about 8 percent of quotes in the CPI sample (excluding the rent sample) are from online outlets; this is close to the estimate of online sales from the U.S. Census Bureau’s quarterly retail sales survey. As expected, the percentage of quotes from online sources varies greatly depending on the item category.
Why is CPI seasonally adjusted?
By using seasonally adjusted data, some users find it easier to see the underlying trend in short-term price changes. It is often difficult to tell from raw (unadjusted) statistics whether developments between any 2 months reflect changing economic conditions or only normal seasonal patterns. Therefore, many economic time series, including the CPI, are adjusted to remove the effect of seasonal influences—those which occur at the same time and in about the same magnitude every year. Among these influences are price movements resulting from changing weather conditions, production cycles, changeovers of models, and holidays.

How does CPI work?
The CPI seeks to measure the change in the cost of living by measuring the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. For the CPI to be accurate, the market basket must correspond to what consumers are actually purchasing, and the different categories of items must be weighted to reflect their proportions in consumers' budgets. The CPI uses data from the Consumer Expenditure (CE) survey to determine the weights of the different categories of goods and services in the CPI. The CE survey collects data on the out-of-pocket expenses spent to acquire all consumer products and services. The CPI uses the CE data to identify the goods within the CPI's scope. Information about the scope of the CPI is available in the concepts section. Annual CE data are used for the CPI-U and CPI-W weights; these expenditure weights are updated biennially. For example, annual CE data from 2015 and 2016 were used to construct a set of weights that were implemented in the CPI at the end of 2017 and were used through the end of 2019. Additional information about the CE survey is available in the Consumer Expenditure section of the BLS Handbook of Methods.

When you divide the current product price total by the past price total, your equation is 8.50 / 6.75 = 1.26. You'd then multiple this total by 100, which would be 1.44 x 100 = 125.9. Subtract this total from 100 to receive your final percentage of change, which is 25.9%. This means there is a 25.9% change in product prices since 2018. The entire equation would be 9.70 / 8.50 = 1.26 x 100 = 125.9 - 100 = 25.9.

The Consumer Prices Index including owner occupiers’ housing costs (CPIH) rose by 2.9% in the 12 months to September 2021, down from 3.0% to August.

The Office for National Statistics’ (ONS) blog Beware Base Effects describes how relatively low prices for some items during and after that period influence current inflation rates. In particular, in August 2020, many prices in restaurants and cafes were discounted because of the government’s Eat Out to Help Out (EOHO) scheme, which offered customers half price food and drink to eat or drink in (up to the value of £10) between Mondays and Wednesdays.

How are item indices imputed?
For the first month in which they become available again, item indices are imputed using either the monthly movement in the all-available-items index or, for a smaller number of seasonal items, the annual movement in the all-available-items index. The aim is that the indices for returning items have a negligible impact on the all-items inflation rate in the first month of return, reflecting the fact that these services are available only as price levels and do not have price growth associated with them (relative to the January base). Collected prices then start to influence the index in the following month.
