Pricing information is then sent to our national office, where specialists who have detailed knowledge about the particular goods or services review the data. These specialists check the data for accuracy and consistency, and make any necessary corrections or adjustments. Adjustments can range from an adjustment for a change in the size or quantity of a packaged item, to more complex adjustments based upon statistical analysis of the value of an item's features or quality.
Thus, commodity specialists strive to prevent changes in the quality of items from affecting the CPI's measurement of price change. 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 , 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. As expected, the percentage of quotes from online sources varies greatly depending on the item category.
Taxes that are directly associated with the purchase of specific goods and services such as sales and excise taxes , as well as government user fees, are included in the CPI. For example, toll charges and parking fees are included in the transportation category, and entry fees to national parks are included as part of the admissions index.
In addition, property taxes are indirectly reflected in the BLS method of measuring the cost of the flow of services provided by shelter, called owners' equivalent rent , to the extent that these taxes influence rental values.
Taxes not directly associated with specific purchases, such as income and Social Security taxes, are excluded, as are the government services paid for through those taxes. Various indexes have been devised to measure different aspects of inflation.
Inflation has been defined as a process of continuously rising prices or, equivalently, of a continuously falling value of money. The CPI measures inflation as experienced by consumers in their day-to-day living expenses; the Producer Price Index PPI measures inflation at earlier stages of the production process; the International Price Program IPP measures inflation for imports and exports; the Employment Cost Index ECI measures inflation in the labor market; and the Gross Domestic Product GDP Deflator measures inflation experienced by both consumers themselves as well as governments and other institutions providing goods and services to consumers.
There are also specialized measures, such as measures of interest rates. The "best" measure of inflation depends on the intended use of the data. The CPI is generally the best measure for adjusting payments to consumers when the intent is to allow consumers to purchase at today's prices, a market basket of goods and services equivalent to one that they could purchase in an earlier period.
CPI data are reported on a not seasonally adjusted basis as well as a seasonally adjusted basis. Sometimes the index level itself will be reported, but it is also common to see 1-month or month percent changes reported. In addition to the all items index, BLS publishes thousands of other consumer price indexes, such as all items less food and energy.
Some users of CPI data use this index because food and energy prices are relatively volatile, and they want to focus on what they perceive to be the "core" or "underlying" rate of inflation. An index is a tool that simplifies the measurement of movements in a numerical series. That is, BLS sets the average index level representing the average price level for the month period covering the years , , and equal to ; then measures changes in relation to that figure.
An index of , for example, means there has been a percent increase in price since the reference period; similarly, an index of 90 means there has been a percent decrease. Movements of the index from one date to another can be expressed as changes in index points simply, the difference between index levels , but it is more useful to express the movements as percent changes. This is because index points are affected by the level of the index in relation to its reference period, while percent changes are not.
Yet, because of different starting indexes, both items had the same percent change; that is, prices advanced at the same rate. By contrast, Items B and C show the same change in index points, but the percent change is greater for Item C because of its lower starting index value. The decision to employ an escalation mechanism, as well as the choice of the most suitable index, is up to the user.
When the terms of an escalation contract are drafted, both legal and statistical questions can arise. While we cannot help in matters relating to legal questions, we can provide basic technical and statistical assistance to users who are developing indexing procedures.
In general, for escalation, we strongly recommend using indexes that are not seasonally adjusted. We also recommend using national or regional indexes, due to the volatility of local indexes.
Another consideration is whether to use a particular monthly index from one year to the next, such as December to December, or use annual averages. From a statistical perspective, each of these types of indexes has its advantages. A month percent change from, say, December-to-December, is arguably a more recent estimate of price change than an annual average percent change.
Said another way, the December-to-December percent change is the most recent month percent change in a year, while the annual average percent change reflects the change in the average index for all 12 months of one year to the average index for all 12 months the next year.
The December-to-December index percent change, however, tends to be more volatile than the percent change in the annual average index. Annual average indexes are based on 12 monthly data points which, when averaged, reduce volatility by smoothing out the highs and lows.
When drafting a contract that uses an index series for escalation, it is helpful to be as specific as possible so that all parties will be clear about the terms. 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. Seasonally adjusted indexes that have been published earlier are subject to revision for up to 5 years after their original release. Therefore, unadjusted data are more appropriate for escalation purposes.
For the CPI-U, an extensive set of component indexes and sub-aggregates are published monthly along with the all items index. A similar, but slightly smaller set is published for the CPI-W.
For the C-CPI-U, only national indexes are published, with a more limited set of components and aggregates published. The set of components and sub-aggregates published for regional and metropolitan indexes is more limited that at the U.
Each local index has a much smaller sample size than the national or regional indexes and is, therefore, subject to substantially more sampling and other measurement error.
As a result, local-area indexes are more volatile than the national or regional indexes, and we urge users to consider adopting the national or regional CPIs for use in escalator clauses. Used with caution, local-area CPI data can illustrate and explain the impact of local economic conditions on consumers' experience with price change. If there is no CPI for the area you are in, we can provide some guidance on a recommended area to use instead, but users must make the final decision.
No, an individual area index measures how much prices have changed over a specific period in that particular area; it does not show whether prices or living costs are higher or lower in that area relative to another.
In general, the composition of the market basket and the relative prices of goods and services in the market basket during the expenditure base period vary substantially across areas.
One limitation is that the CPI may not be applicable to all population groups. The CPI does not produce official estimates for the rate of inflation experienced by subgroups of the population, such as the elderly or the poor. Note that we do produce an experimental index for the elderly population that is available upon request; however, because of the significant limitations of this experimental index, it should be interpreted with caution.
Another limitation is that the CPI cannot be used to measure differences in price levels or living costs between one area and another as it measures only time-to-time changes in each area. A higher index for one area does not necessarily mean that prices are higher there than in another area with a lower index. Instead, it means that prices have risen faster in the area with the higher index calculated from the two areas' common reference period. Additionally, the CPI is a conditional cost-of-living measure; it does not attempt to measure everything that affects living standards.
Factors such as social and environmental changes and changes in income taxes are beyond the definitional scope of the index and are excluded. Limitations in measurement can be grouped into two basic types, sampling error and non-sampling error.
Because the CPI measures price changes based on a sample of items, the published indexes differ somewhat from what the results would be if actual records of all retail purchases by everyone in the index population could be used to compile the index. These estimating or sampling errors are limitations on the accuracy of the index, not mistakes in calculating the index. The CPI program has developed measurements of sampling error, called variance estimates, which are updated and published annually at CPI Variance Estimates.
The CPI sample design allocates the sample in a way that maximizes the accuracy of the index, given the funds available. These errors occur from a variety of sources and unlike sampling errors, they can cause persistent bias in measurements of the index. Non-sampling errors are caused by problems of price data collection, logistical lags in conducting surveys, difficulties in defining basic concepts and their operational implementation, and difficulties in handling the problems of quality change.
Non-sampling errors can be far more hazardous to the accuracy of a price index than sampling errors so we expend considerable effort to minimize these errors. Highly trained personnel ensure the comparability of quality of items from period to period; collection procedures are extensively documented, and recurring audits are conducted.
The CPI program has an ongoing research and evaluation program in order to identify and implement improvements in the index. The CPI will need revisions as long as there are significant changes in consumer buying habits or shifts in population distribution or demographics. By developing annual Consumer Expenditure Surveys and Point-of-Purchase Surveys, the Bureau has the flexibility to monitor changing buying habits in a timely and cost-efficient manner.
In addition, the census conducted every 10 years by the U. Census Bureau provides information that enables us to reselect a new geographic sample that accurately reflects the current population distribution and other demographic factors.
BLS is continually researching improved statistical methods, so even between major revisions, improvements are made to the CPI. Information on the CPI is available from our website and through email subscriptions to data products, and a variety of publications. Information specialists are also available in the national and regional offices to provide assistance via email or telephone.
BLS provides free access to published CPI data via press releases, tables, and current and historical data from our database. BLS has a stat for that! You can subscribe to our national news release or regional data products by using the BLS News Service feature. Recorded summaries of national and local CPI data may be obtained by calling one of the following metropolitan area CPI hotlines.

US Department of Labor. Bureau of Labor Statistics. What is the CPI? How is the CPI market basket determined? How is the CPI sample created? How is the CPI calculated? How is the CPI used?
Whose buying habits does the CPI reflect? What types of data are published? Is the CPI a cost-of-living index? What goods and services does the CPI cover? How are CPI prices collected and reviewed? Does the CPI collect prices from online outlets? How are taxes treated in the CPI? Is the CPI the best measure of inflation? Now let us turn to governmental efforts to lower prices or at least to keep them from rising. These efforts occur repeatedly in most nations, not only in wartime, but in any time of inflation.
Let us say it begins with bread and milk and other necessities. But this is exactly the opposite result from what the price controllers had in mind. If the government then tries to prevent this discouragement to the production of the controlled commodities by keeping down the cost of the raw materials, labor and other factors of production that go into them, it must start controlling prices and wages in ever-widening circles until it is finally trying to control the price of everything.
It will be fixing rigid allocations and quotas for each producer and for each consumer. And these price changes, both absolute and relative, are in the overwhelming main both necessary and desirable. They are producing thousands of goods and services in the relative amounts in which they are socially wanted.
These relative amounts are changing every day. Price Control Distorts Production. What governments never realize is that, so far as any individual commodity is concerned, the cure for high prices is high prices. High prices lead to economy in consumption and stimulate and increase production. Both of these results increase supply and tend to bring prices down again.
Very well, someone may say; so government price control in many cases is harmful. But what of monopolistic markets? What of markets in which prices are controlled or fixed by huge corporations?
Unwarranted Fears of Monopoly. If there is only a single drug store, barber shop, or grocery in a small isolated town and this is a typical situation , this store may be said to be enjoying a monopoly in that town. Again, everybody may be said to enjoy a monopoly of his own particular qualities or talents. On the other hand, nearly all economic monopolies are limited by the possibility of substitution. If copper piping is priced too high, consumers can substitute steel or plastic; if beef is too high, consumers can substitute lamb; if the original girl of your dreams rejects you, you can always marry somebody else.
A Strange Numbers Game. The prosecutors and the courts have recently been playing a strange numbers game. In , for example, a Federal district court held that a merger that had taken place between two New York City banks four years previously had been illegal, and must now be dissolved.
I should add that in the four years since the merger the number of branch bank offices in New York City had increased from to There is this much truth in this political theory as applied in the economic realm.
If they are really competing, only two firms in an industry are enough to create effective competition. The theory that there can be such a thing as a monopoly price, higher than a competitive price would have been, is certainly valid. He does not know; he can only guess; he must try to find out by trial and error. In any case, in the absence of competition, no one knows what the "competitive" price would be if it existed. For when there is an alleged conspiracy to fix prices, purchasers are encouraged to sue to recover three times the amount they were allegedly forced to "overpay.
It all depends on the economic bias of a particular court or judge. There is immense hypocrisy about the subject. To work our way out of this existing legal chaos is, of course, a task for jurists as well as for economists. I have one modest suggestion: We can get a great deal of help from the old common law, which forbids fraud, misrepresentation, and all physical intimidation and coercion.
Arbitrary power, enforcing its edicts to the injury of the persons and property of its subjects, is not law, whether manifested as the decree of a personal monarch or of an impersonal multitude. And the limitations imposed by our constitutional law upon the action of the government, both State and national, are essential to the preservation of public and private rights, notwithstanding the representative character of our political institutions.
