The CPI is a product of a series of interrelated samples. First, using data from the U. Census we select the urban areas from which data on prices are collected. Next, another sample of about 14, families each year serves as the basis for a Telephone Point-of-Purchase Survey TPOPS that identifies the places where households purchase various types of goods and services, forming the basis for the CPI outlet sample.
Recorded price changes are weighted by the importance of the item in the spending patterns of the appropriate population group. The combination of carefully selected geographic areas, retail establishments, commodities and services, and associated weight, gives a weighted measurement of price change for all items in all outlets, in all areas priced for the CPI. The CPI affects nearly all Americans because of the many ways it is used.
Some examples of how it is used follow:. As an economic indicator. The CPI is the most widely used measure of inflation and is sometimes viewed as an indicator of the effectiveness of government economic policy.
It provides information about price changes in the Nation's economy to government, business, labor, and private citizens and is used by them as a guide to making economic decisions. As a deflator of other economic series. The CPI and its components are used to adjust other economic series for price changes and to translate these series into inflation-free dollars. Examples of series adjusted by the CPI include retail sales, hourly and weekly earnings, and components of the National Income and Product Accounts.
The CPI is also used as a deflator of the value of the consumer's dollar to find its purchasing power. The purchasing power of the consumer's dollar measures the change in the value to the consumer of goods and services that a dollar will buy at different dates.
In other words, as prices increase, the purchasing power of the consumer's dollar declines. As a means of adjusting dollar values. The CPI is often used to adjust consumers' income payments for example, Social Security , to adjust income eligibility levels for government assistance, and to automatically provide cost-of-living wage adjustments to millions of American workers. As a result of statutory action, the CPI affects the income of millions of Americans. Another example of how dollar values may be adjusted is the use of the CPI to adjust the Federal income tax structure.
These adjustments prevent inflation-induced increases in tax rates. In addition, eligibility criteria for millions of food stamp recipients, and children who eat lunch at school, are affected by changes in the CPI. Many collective bargaining agreements also tie wage increases to the CPI. The CPI reflects spending patterns for each of two population groups: The all urban consumer group represents about 93 percent of the total U.
It is based on the expenditures of almost all residents of urban or metropolitan areas, including professionals, the self-employed, the unemployed, and retired people, as well as urban wage earners and clerical workers. Not included in the CPI are the spending patterns of people living in rural nonmetropolitan areas, those in farm households, people in the Armed Forces, and those in institutions, such as prisons and mental hospitals.
The CPI does not necessarily measure your own experience with price change. It is important to understand that BLS bases the market baskets and pricing procedures for the CPI-U and CPI-W populations on the experience of the relevant average household, not of any specific family or individual. For example, if you spend a larger-than-average share of your budget on medical expenses, and medical care costs are increasing more rapidly than the cost of other items in the CPI market basket, your personal rate of inflation may exceed the increase in the CPI.
Conversely, if you heat your home with solar energy, and fuel prices are rising more rapidly than other items, you may experience less inflation than the general population does. A national average reflects millions of individual price experiences; it seldom mirrors a particular consumer's experience.
Many types of data are published as outputs from the CPI program; the most popular are indexes and percent changes. Requested less often are relative importance or relative expenditure weight data, base conversion factors to convert from one CPI reference period to another , seasonal factors the monthly factors used to convert unadjusted indexes into seasonally adjusted indexes , and average food and energy prices.
Index and price change data are available for the U. Indexes for various groupings of items are available for all geographic areas and size classes. Index levels are published along with short-term percent changes and month percent changes. At the national item and group level, unadjusted and where appropriate seasonally adjusted percent changes are also published. Average prices for select utility, automotive fuel, and food items are published at the U. If the sample size is sufficient, all average prices are also published monthly at the regional level.
Average prices for utility gas, electricity, and automotive fuel prices are also published at the size class and area level. Congress amended the Social Security Act of with public law in Part of that amendment called for automatic annual cost of living increases to be made to Social Security payments based on the CPI.
BLS calculates the CPI-W and other CPI series, but we do not determine policy regarding how these series are used by other agencies, nor are we involved in making or adjusting Social Security payments.
The CPI frequently is called a cost-of-living index, but it differs in important ways from a complete cost-of-living measure. We use a cost-of-living framework in making practical decisions about questions that arise in constructing the CPI. A cost-of-living index is a conceptual measurement goal, however, and not a straightforward alternative to the CPI. A cost-of-living index would measure changes over time in the amount that consumers need to spend to reach a certain utility level or standard of living.
Both the CPI and a cost-of-living index would reflect changes in the prices of goods and services, such as food and clothing that are directly purchased in the marketplace; but a complete cost-of-living index would go beyond this role to also take into account changes in other governmental or environmental factors that affect consumers' well-being.
It is very difficult to determine the proper treatment of public goods, such as safety and education, and other broad concerns, such as health, water quality, and crime, that would constitute a complete cost-of-living framework.
Since the CPI does not attempt to quantify all the factors that affect the cost-of-living, it is sometimes termed a conditional cost-of-living index.
Traditionally, the CPI was considered an upper bound on a cost-of-living index in that the CPI did not reflect the changes in buying or consumption patterns that consumers would make to adjust to relative price changes.
The ability to substitute means that the increase in the cost to consumers of maintaining their level of well-being tends to be somewhat less than the increase in the cost of the mix of goods and services they previously purchased. Since January , a geometric mean formula has been used to calculate most basic indexes within the CPI; in other words, the prices within most item categories for example, apples are averaged with the use of a geometric mean formula.
This improvement moves the CPI closer to a cost-of-living measure, because the geometric mean formula allows for a modest amount of consumer substitution as relative prices within item categories change. However, the expenditure data used to compute the final C-CPI-U isn't available until months after the reference month, so a preliminary estimate of the index is published and later revised.
The CPI represents all goods and services purchased for consumption by the reference population U or W. BLS has classified all expenditure items into more than categories, arranged into eight major groups food and beverages, housing, apparel, transportation, medical care, recreation, education and communication, and other goods and services.
Included within these major groups are various government-charged user fees, such as water and sewerage charges, auto registration fees, and vehicle tolls. In addition, the CPI includes taxes such as sales and excise taxes that are directly associated with the prices of specific goods and services. However, the CPI excludes taxes such as income and Social Security taxes not directly associated with the purchase of consumer goods and services.
The CPI also does not include investment items, such as stocks, bonds, real estate, and life insurance because these items relate to savings, and not to day-to-day consumption expenses. For each of the item categories, using scientific statistical procedures, the Bureau has chosen samples of several hundred specific items within selected business establishments frequented by consumers to represent the thousands of varieties available in the marketplace. For example, in a given supermarket, the Bureau may choose a plastic bag of golden delicious apples, U.
BLS data collectors visit in person or on the web or call thousands of retail stores, service establishments, rental units, and doctors' offices, all over the United States to obtain information on the prices of the thousands of items used to track and measure price changes in the CPI. We record the prices of about 80, items each month, representing a scientifically selected sample of the prices paid by consumers for goods and services purchased. During each call or visit, the data collector collects price data on a specific good or service that was precisely defined during an earlier visit.
If the selected item is no longer available, or if there have been changes in the quality or quantity for example, a ounce container has been replaced by a ounce container of the good or service since the last time prices were collected, a new item is selected or the quality change in the current item is recorded. Prices used to compute the CPI are collected during the entire month. CPI data is published monthly, with the index value representing an estimate of the price level for the month as a whole, rather than a specific date.
Since certain prices, particular gasoline, might move sharply within a month, it is useful to understand the timing of price collection. A month is divided into three pricing periods, each period corresponding to roughly the first ten days, second ten days, or third ten days of the month. When an item is initiated into the CPI sample, its pricing period is established, and it will be repriced during that same period until it exits the sample after four years.
Data collectors have discretion within pricing periods, so they can collect quotes at any time during the period. So, it's not necessarily true that data collection is spread perfectly evenly through the month; however, roughly equal amounts of data are collected in each pricing period. Rent prices are an exception to this, as prices in the rent sample are not divided by pricing periods, and specific rent quotes can be collected at any time during the month. 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 why the constant attempts of governments to lower, raise, or freeze a particular price, or to freeze the interrelationship of wages and prices just where it was on a given date "holding the line" are bound to be disruptive wherever they are not futile.
Price Supports for Export Items. Let us begin by considering governmental efforts to keep prices up, or to raise them. Thus Japan once did it for silk and the British Empire for natural rubber; Brazil has done it and still periodically does it for coffee; and the United States has done it and still does it for cotton and wheat. All of these schemes follow a typical course. This may lead in the beginning to the imposition of acreage restrictions.
The result of this quota system is to keep out all new competition; to lock all existing producers into their previous relative position, and therefore to keep production costs high by removing the chief mechanisms and incentives for reducing such costs. Foreigners object to paying the higher price. The higher price gives an incentive to other countries to start producing the valorized commodity. This not only lowered rubber prices, but caused the British to lose permanently their previous monopolistic position.
Meanwhile, at home, all these schemes require the setting up of an elaborate system of controls and an elaborate bureaucracy to formulate and enforce them. In , before most of the crop control schemes came into being, there were 24, persons employed in the Department of Agriculture. None of these consequences seem to discourage government efforts to boost prices of certain products above what would otherwise be their competitive market levels.
We still have international coffee agreements and international wheat agreements. These quotas force all American consumers to pay higher prices for sugar in order that a tiny minority of American sugar cane producers can get higher prices. 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.
Also the government determines the price goods will be sold at. Communism (competition) In a communist economy there is no competition, because everything is owned by the government.
The government determines prices for goods and services in a command economy. In fact, in a command economy the government has control over all financial aspects of the country, including prices, pay rates for workers and division of resources.
