Basic foods and beverages, such as cereal, milk, and coffee, are included in the basket of goods. Housing expenditures, bedroom furnishings, apparel, transportation costs, medical care costs, leisure expenses, toys, and museum entry fees are all included. The government also includes additional random products like tobacco, haircuts, and funerals in the basket’s contents, as well as education and communication costs.
What is included in the rate of inflation?
The price change of goods and services excluding food and energy is the core inflation rate. Food and energy products are too perishable to be included in the list. They fluctuate so quickly that an accurate reading of underlying inflation trends can be thrown off.
What does the CPI basket usually contain?
Every year, the “shopping baskets” of items used to compile the various consumer price inflation measures are reassessed. To ensure that the metrics are current and indicative of consumer spending habits, certain products are removed from the baskets and others are added.
In 2021, 17 new categories, including the owner occupiers’ housing costs (CPIH) basket, were introduced to the Consumer Prices Index, while 10 items were eliminated.
This article covers how and why the various items in the consumer price inflation baskets are picked during the review process. Annexes A and B summarize the contents of the baskets for 2021, and this article discusses the significant differences from the 2020 price collection. In past years, similar pieces were published.
The following are the consumer price inflation metrics discussed in the article.
CPIH
The most complete measure of consumer price inflation, which expands the CPI to include owner occupiers’ housing prices (OOH) and Council Tax. CPIH is identical to CPI except for these two components.
Consumer Prices Index (CPI)
A measurement that has been created in accordance with international standards. The CPI is the inflation measure used in the government’s inflation target. It was first released in 1997 as the Harmonised Index of Consumer Prices (HICP).
Retail Prices Index (RPI)
Because of its use in long-term contracts and index-linked gilts, we continue to report this legacy measure in compliance with the Statistics and Registration Service Act 2007. In 2013, the Retail Prices Index and its derivatives were evaluated under the Code of Practice for Statistics and judged to be ineligible for classification as a National Statistic. The difficulties are described as shortcomings of the Retail Prices Index as a gauge of inflation.
In 2019, the UK Statistics Authority proposed that the RPI be discontinued at some point in the future, and that in the meanwhile, the RPI’s deficiencies be rectified by incorporating CPIH data sources and methodologies into its production. Following that, the Authority and HM Treasury published a consultation (PDF, 531KB) on the Authority’s proposal to rectify the RPI’s flaws.
In addition, as a result of the coronavirus (COVID-19) pandemic, this page summarizes another adjustment relating to the update of weights for 2021. This is covered in Section 4, which also includes links to other in-depth articles on the subject.
The shopping basket
The rate at which the prices of goods and services purchased by households grow or fall is referred to as consumer price inflation. Imagine a very huge “shopping basket” holding all of the items and services purchased by households. The overall cost of the basket changes as the prices of the individual goods in the basket fluctuate over time. The changing cost of the shopping basket is represented by changes in consumer price inflation indexes.
In theory, the basket should include all consumer goods and services purchased by households, as well as the prices paid in each shop or outlet that sells them. In practice, consumer price indices are constructed by gathering a sample of prices for a variety of representative items and services from a variety of UK retail outlets, including the internet.
In order to create the indexes, over 180,000 unique price quotations are collected every month, spanning over 720 sample consumer goods and services. These costs are gathered in around 140 places across the United Kingdom, as well as on the internet and over the phone. All costs were collected via phone and the internet during the coronavirus (COVID-19) lockdowns. In addition, each month, roughly 300,000 bids are utilized to calculate the expenses of housing for owner-occupiers. This indicator is primarily based on data from administrative sources.
Consumer price indices indicate the changing cost of a basket of products and services with a fixed composition, quantity, and quality over the course of a year. This is accomplished in practice by:
- assigning a set of weights to price changes for each of the goods, so that their impact on the aggregate index reflects their relevance in a typical household budget
- ensuring that substitutes for brands that are no longer available in a certain store are of equivalent quality
In this way, monthly fluctuations in consumer price indices reflect simply price changes, not continuous differences in the quality and quantity of things purchased by consumers.
The contents of the consumer price inflation basket of goods and services, as well as their related expenditure weights, are changed annually, although remaining consistent year to year. This is crucial because it helps to minimize biases that could emerge over time. This could be due to the emergence of wholly new goods and services, or because consumers are shifting away from purchasing goods and services whose prices have risen rapidly in favor of goods and services whose costs have decreased. For example, if the price of tea climbed considerably over the course of a year, consumers may shift their spending to coffee, necessitating an adjustment to the expenditure weights the following year.
These measures also ensure that the indices accurately reflect long-term trends in consumer purchasing habits. For example, over the previous 25 years, the proportion of household expenditure devoted to services has climbed steadily. This is reflected in the addition of new goods to the basket to enhance assessment of price changes in this sector, such as playgroup and nanny fees, as well as an increase in the weight for this component in consumer price indexes.
Each year, changes to the items and corresponding item weights are introduced in the February index, but prices for both old and new goods are collected in January. This means that the values for each year can be “chained” together to generate a multi-year price index. To put it another way, price changes from December to January are based on the old basket, and price changes from January to February and beyond are based on the new basket. This approach assures that annual basket changes do not result in a price discontinuity as evaluated by the indexes.
A basic guide to consumer pricing indices: The year 2017 serves as an excellent primer on the concepts and techniques that underpin the development of consumer price indices. Consumer Price Indices – Technical Manual and CPIH Compendium go into considerably more information on these topics.
The Consumer Prices Index including owner occupiers’ housing costs (CPIH) and Consumer Prices Index (CPI) inflation baskets differ in actuality because CPIH contains a measure of owner occupiers’ housing costs and Council Tax, which are not included in CPI. Some goods not included in the Retail Prices Index (RPI) basket, such as university accommodation fees and unit trust commissions, are included in both the CPIH and CPI baskets. Similarly, the RPI basket includes several products that are not included in the CPIH and CPI baskets (for example, estate agency fees). The actual weights of the individual products vary as well. Users and uses of consumer price inflation statistics discusses the distinctions between the inflation measures.
Representative items
Some specific commodities and services have such high average household spending that they deserve to be included in the baskets on their own: for example, gasoline and power supply. However, measuring price changes of every item purchased by every home in order to compile consumer price indices would be impracticable.
Typically, a sample of specific goods and services must be chosen that provides a valid estimate of price changes for a larger range of related items. Price fluctuations for garden spades, for example, may be indicative of price changes for other garden tools. Because creating an adequate sampling frame, that is, a list of all the individual goods and services purchased by families, is challenging, the selection of these representative items is judgmental. When selecting representative items, this limits the use of typical random sampling methods. Instead, selection is based on research into the many things that could be employed, both through market research data and inquiry in outlets around the country.
A number of items are chosen for each product grouping whose price fluctuations, when added together, provide a good indication of the overall change in pricing for the group. The Consumer Prices Index, for example, contains roughly 20 typical items, including owner occupiers’ housing expenses (CPIH) “The prices from the “furniture and furnishings” class are used to produce an overall estimate of price change for all furniture items. These include everything from beds to kitchen cabinets.
The prices obtained for each product group are then merged to create overall consumer price indices, with weights proportional to total product group expenditure. As a result, the importance attributed to “The CPIH shopping basket item “furniture and furnishings” reflects average household spending on all furniture products rather than just the basket items. Similarly, the weight of garden spades is determined by the total amount spent on all garden tools.
Selecting the representative items
When selecting representative goods, a variety of variables must be considered. Of course, the items must be easy to locate for the team collecting the price quotations, ensuring that price change estimations are based on a sufficient number of quotes received across the United Kingdom.
Consumer price inflation figures should, ideally, be available for purchase throughout the year because they are based on the cost of fixed in-year baskets of goods and services. Some clothes and garden items, on the other hand, are clearly seasonal, and hence demand a slightly different handling in the indices. Patio furniture costs, for example, are only collected during the summer months, when the item is most commonly found in stores. During the winter, their index is based on the pricing of other things in the basket’s furnishings area.
The number of items chosen to represent each product group within the indices is determined by the group’s weight (i.e., spending) as well as the variety of price changes among the numerous items that could be picked to represent the group (reflecting, for example, the diversity of products available). It is intuitive to choose more things in product categories when expenditure is high. This reduces sampling variability in price change estimates for high-weighted groups and, as a result, in the overall price index.
However, if the price movements of all available goods in the group are relatively similar, only collecting prices for a handful is adequate. At the extreme, if the price fluctuations for all of the possible goods in a particular group were identical each month, only one of the items could be chosen for inclusion in the basket. Price changes for this one item would be an excellent indicator of price changes for the entire group. If, on the other hand, the price movements of all potential products are quite disparate, prices for a large number of representative items will be required to obtain a reliable overall estimate of price change for the group.
The allocation of goods to broad commodity categories can then be examined, as indicated in Table 1 for the 12 divisions of the Consumer Prices Index, including owner occupiers’ housing costs (CPIH), with the balance serving as a reference point for the annual assessment of the baskets.
The relatively high range in observed price changes across individual goods in this sector, for example, explains part of the significant allocation of items to the food division relative to its index weight. The restaurants and hotels category, on the other hand, receives a smaller number of items compared to index weight, indicating that observed price movements are more similar.
The inclusion of some prominent individual items (for example, automobile purchase and motor fuels, and owner occupiers’ housing expenditures and housing rents, respectively) can explain apparent low allocations of items in some circumstances, such as transportation and housing. The rationale for adding more items to improve coverage of the remaining index weights in these divisions is substantially weaker in this scenario. Instead, it’s significantly more crucial to make sure that the price sampling for these heavily weighed commodities is as broad as feasible.
What does the market basket include?
Components outside the purview of consumer goods and services are included in the CPI’s market basket. The market basket includes government taxes for public products such as water and sewage, for example. Taxes on products and services that are already part of the market basket are also included. Stocks and bonds, on the other hand, are not included in the market basket. In essence, the market basket represents all commodities and services purchased and sold by the CPI’s population.
What isn’t factored into the inflation rate?
The Most Important Takeaways Core inflation refers to the change in the cost of goods and services excluding the food and energy sectors. Food and energy prices are not included in this computation since they are too volatile and fluctuate too much.
What is excluded from the CPI basket?
The CPI measures the spending habits of two categories of people: all urban consumers and urban wage earners and clerical workers. The all-urban consumer group accounts for roughly 93 percent of the overall population of the United States. It is based on the expenditures of practically all urban or metropolitan residents, including professionals, self-employed, jobless, and retired persons, as well as urban wage earners and clerical workers. The spending habits of those residing in rural nonmetropolitan areas, agricultural households, members of the Armed Forces, and those in institutions such as prisons and mental hospitals are not included in the CPI. The Consumer Price Index for All Urban Consumers (CPI-U) and the Chained Consumer Price Index for All Urban Consumers (CCPI-U) are two indexes that assess consumer inflation for all urban consumers (C-CPI-U).
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is based on the expenditures of households that meet two additional criteria: more than half of the household’s income must come from clerical or wage occupations, and at least one of the household’s earners must have worked for at least 37 weeks in the previous year. The CPI-W population is a subset of the CPI-U population, accounting for around 29% of the overall US population.
The CPI does not always reflect your own experience with price changes. It’s crucial to note that the BLS’s market baskets and pricing methodologies for the CPI-U and CPI-W populations are based on the experiences of the relevant average household, not any particular family or individual. If you spend a higher-than-average percentage of your budget on medical expenses, and medical care costs are rising faster than the cost of other commodities in the CPI market basket, your personal rate of inflation may outpace the CPI. In contrast, if you use solar energy to heat your home and fuel prices are rising faster than other things, you may experience lower inflation than the general population. A national average reflects millions of individual price experiences, yet it rarely replicates the experience of a single consumer.

What exactly is an inflation basket?
Statistics The Consumer Price Index (CPI) basket of goods and services in South Africa has been updated, providing insight into how consumer purchasing patterns have changed over the last five years.
Every four to five years, South Africa’s CPI basket is evaluated to ensure that it effectively represents trends in household expenditure, technology, and consumer tastes.
The procedure entails deleting things that are no longer relevant and replacing them with new ones that have attracted a significant amount of consumer spending.
The CPI basket will now contain 415 items, up from 404 in 2016, according to the most recent update, released in January 2022 and referencing the year 2019. A total of fourteen new items were added to the basket, while two items were withdrawn. Some products were divided into two or merged into one.
Changes in consumer technology have a significant impact on the basket’s content. DVD players and satellite dishes are no longer included in this version, however soundbars and speakers are. Rewritable CDs and postal stamps were removed from the basket in the 2016 update.
A few changes were made to the goods that were already in the basket. The category ‘internet usage’ was split into wired (e.g. fiber) and wireless (e.g. cellular) modes of access as the use of data services grew.
Following the near-extinction of incandescent bulbs, energy-saving and traditional lightbulbs were formerly classified as different items and merged into one offering. To reflect the growing customer interest for streaming music services, the item ‘pre-recorded CDs’ was renamed ‘CDs, subscription, and streaming music.’
Gin is the only new addition to the category of alcoholic beverages, demonstrating its growing popularity among South African consumers. Cappuccino sachets, dairy/fruit juice blends, samp, pureed baby food, and jam have all been added to the basket.
Personal care items like razors, wipes, and foundation, as well as domestic items like floor and wall tiles, and fabric softener, all made the cut.
“The inflation basket serves as the foundation for calculating the consumer price index (CPI).” All prices for the basket’s contents are collected on a regular basis. “Statis SA calculates the inflation rate, or change in the cost of living, by measuring changes in these prices,” Stats SA added.
What will be in the 2020 basket of goods?
While there were hints of a shift toward better eating and less use of single-use plastic, the ONS noted the shifts also reflected Britain’s love of alcohol. Cocktails in a can and gin sales in restaurants and bars are among the items in the 2020 basket.
The ONS stated that it was making a few minor tweaks to the basket. An MP4 player was replaced by a portable digital music player, while DVD players and Blu-Ray disc players were combined into one product category.
Individual fruit pies, frozen chicken pieces, and frozen imported legs of lamb were among the items removed from the basket.
Each month, the ONS collects prices for 720 representative goods and services from 140 sites, the internet, and over the phone to calculate inflation.
Hundreds of fieldworkers are employed around the United Kingdom to monitor pricing on the same items in the same stores on a monthly basis. Their findings, which include everything from the cost of a pound of beef to the cost of a gym membership, are then forwarded to the ONS office in Newport, Wales, where the rate of inflation is calculated.
Every year, the basket of goods and services, as well as the weight assigned to each item, is examined to verify that the government’s cost-of-living yardstick appropriately reflects how consumers spend their money. Inflation is currently at 1.8 percent, slightly below the government’s objective of 2 percent, with new data expected out next week.
In 2019, the basket was expanded to include smart speakers and bakeware, while envelopes were deleted. Quiche was brought in the year before, but pork pies were not.
“This year we have added reusable bottles and mugs to the inflation basket, since there has been a spike in popularity with many consumers trying to reduce their environmental impacts,” said Philip Gooding, senior statistician at the ONS.
“It’s vital to keep in mind that these annual fluctuations account for only a small portion of the total basket. This year, we added 16 new things, eliminated 14 old ones, and adjusted four others, leaving 702 items unchanged.”
What is the size of the market basket?
The grocery department is the store’s beating heart, with aisles brimming with variety, quality, and value. This week’s promoted features and other outstanding value items can be seen on the end caps at the front and back of every aisle.

Inflation benefits who?
Inflation benefits debtors because they can repay creditors with currency that have less purchasing power. 3. Expected inflation resulted in a considerably lower redistribution of income and wealth than unanticipated inflation. a.
