Variance Estimates for Price Changes in the Consumer Price Index 

January -December 2005 

Owen J. Shoemaker 

This article presents variance estimates for 1-month, 2-month, 6-month, and 12-month percent changes in 

the Consumer Price Index for All Urban Consumers (CPI-U). Variance is a measure of the uncertainty 

caused by the use of a sample of retail prices, instead of the complete universe of retail prices. The 

estimates cover the period January 2005 through December 2005.1

 Each month the U.S. Bureau of Labor 

Statistics collects prices from a sample of approximately 77,000 commodities and services (C&S) quotes 

in approximately 25,500 outlets2

 around the United States for the Consumer Price Index (CPI). 

 The most commonly used measure of sampling variability is the standard error of the estimate – the 

square root of the variance. The standard error of the CPI’s change can be used to construct confidence 

intervals to determine whether the change for a particular CPI series is significantly different from zero. 

This information should help users determine which index changes are significant. 

Presentation of findings 

The percent changes in the CPI along with their standard errors were estimated for the 12 months, 

January through December 2005. In summary, tables 1V through 5V show the median values of those 

percent changes, as well as the median values of the standard errors. Table 1V shows this information for 

U.S. city average, and tables 2V through 5V show the same information for the Northeast, Midwest, 

South, and West regions of the country. 

 For example, from January through December 2005, the 1-month changes in the U.S. city average all 

items index had a median value of 0.33 percent. The standard errors of those 12 estimates had a median 

value of 0.06 percent. Margins of error are usually expressed as a statistic’s point estimate plus or minus 

two standard errors, so the margin of error on this CPI’s 1-month change is approximately 0.33 percent 

plus or minus 0.12 percent. Therefore, in a typical 1-month period, the true change in the CPI was 

probably somewhere between 0.21 percent and 0.45 percent. The tables also show median percent 

changes and standard errors for 2- and 6-month intervals and for the full year 2005. Margins of error can 

be calculated for these intervals in the same way as for a 1-month period. 

Analysis of findings 

Analyzing the data reveals three significant observations. First, standard errors increase as one moves 

from the U.S. city average to individual regions of the country and from all items to individual item 

categories. Second, standard errors differ between item categories. Third, the standard errors decrease on 

a relative basis (standard error divided by price change), as the price change interval gets longer. 

 The primary reason standard errors increase as one moves from the U.S. city average to individual 

regions of the country is that sample sizes differ. In general, smaller sample sizes lead to larger standard

 In 1998 significant changes were made to the CPI’s structure and sample, and a new variance calculation system 

was implemented. For information on variances from 1978-1986, 1993-1997 and then 1998 and 1999, see the CPI 

Detailed Report for February 1991, May 1994, February 1998, December 1999, and November 2000, respectively. 2

errors. For example, the U.S. city average all items index is computed each month from the prices of 

approximately 77,000 selected items throughout the United States, and its median standard error for 1-

month changes is 0.06 percent. By contrast, the Northeast region all items index is computed from the 

prices of approximately 17,000 selected items, and its median standard error is 0.20 percent. Regional 

indexes have larger standard errors because their sample sizes are smaller. 

 One can observe this same effect moving from the all items index to individual item categories. 

Again, the U.S. city average all items index is computed each month from the prices of approximately 

77,000 selected items, and its median standard error is 0.06 percent. By contrast, the U.S. city average 

recreation index is computed from the prices of approximately 6,000 items, and its median standard error 

is 0.13 percent, or twice as large. Again, smaller sample sizes lead to larger standard errors. 

 The second significant observation is that standard errors differ between item categories. There are 

two reasons for this. First, item categories differ in sample size. For example, the U.S. city average food 

and beverages index is computed from approximately 31,000 prices each month, while the U.S. city 

average recreation index is computed from approximately 6,000 prices. Therefore, it is not surprising 

that the recreation index has larger standard errors. Second, there are real differences in item category 

price behaviors caused by different selling practices, seasonal influences, and consumer demand. This is 

especially true for the apparel category, in which it is common for the prices of individual items to 

fluctuate by 50 percent or more each month. As a result, standard errors for apparel indexes are large. 

 The third observation is that standard errors decrease, on a relative basis (standard error divided by 

price change), as the price change interval gets longer. For the U.S. city average all items index, the 

median standard error divided by the median percent change is 0.06/0.33 = 0.182 for 1-month changes, 

0.09/0.68 = 0.132 for 2-month changes, 0.12/1.86 = 0.065 for 6-month changes, and 0.10/3.25 = 0.031 

for the 12-month change between December 2004 and December 2005. This shows that the relative 

accuracy of percent changes in the CPI generally improves as the price change interval gets longer. On 

an absolute basis, standard errors tend to increase, but at a decreasing rate. 

 Findings presented here indicate that users should exercise caution when using CPI estimates to make 

inferences about index changes for relatively short time periods, for individual goods and services, or for 

local areas. The standard errors of those estimates may be on the same order of magnitude as the estimates 

themselves; and, thus, few inferences about them are reliable. 

Sources of error 

One way of analyzing the error in a survey estimate is to divide the total error into two sources: sampling 

error and non-sampling error. Sampling error is the uncertainty in the CPI caused by the fact that a 

sample of retail prices is used to compute the CPI, instead of using the complete universe of retail prices. 

Non-sampling error is the rest of the error. Non-sampling error includes things such as incorrect 

information given by survey respondents, data processing errors, and so forth. Non-sampling error arises 

regardless of whether data are collected from a sample of retail prices or from the complete universe. 

 Another way of analyzing error is to divide it into variance and bias. The variance of the CPI is a 

measure of how close different estimates of the CPI would be to each other if it were possible to repeat 

the survey over and over using different samples. Of course, it is not feasible to repeat the survey multiple 

times, but statistical theory allows the CPI’s variance to be estimated anyway. A small variance, for 

example, indicates that multiple independent samples would produce values that are consistently very 

close to each other. Bias is the difference between the CPI’s expected value and its true value. A statistic

may have a small variance but a large bias, or it may have a large variance but a small bias. For an index 

to be considered accurate, both its variance and bias need to be small. 

 The Bureau of Labor Statistics (BLS) is constantly trying to reduce the error in the CPI. Variance and 

sampling error are reduced by using a sample of retail prices that is as large as possible, given resource 

constraints. BLS has developed a model that optimizes the allocation of resources by indicating the 

number of prices that should be observed in each geographic area and each item category, in order to 

minimize the variance of the U.S. city average all items index. BLS reduces non-sampling error through 

a series of computerized and professional data reviews, as well as through continuous survey process 

improvements and theoretical research. 

Replication and variance estimation 

An important advantage of using sampling is that the CPI’s variance can be estimated directly from the 

sample data. Starting in 1978, the CPI’s sample design has accommodated variance estimation by using 

two or more independent samples of items and outlets in each geographic area. This allows two or more 

statistically independent estimates of the index to be made. The independent samples are called replicates, 

and the set of all observed prices is called the full sample. 

 BLS collects CPI data in 38 geographic areas across the United States. These areas consist of 31 selfrepresenting areas and 7 non-self-representing areas. Self-representing areas are large metropolitan areas, 

such as the Boston, St. Louis, and San Francisco metropolitan areas. Non-self-representing areas are 

collections of smaller metropolitan areas. For example, one non-self-representing area is a collection of 

32 small metropolitan areas in the Northeast region (Buffalo, Hartford, Providence, Bangor, and others), 

of which 8 were randomly selected to represent the entire set. Within each of the 38 areas, price data are 

collected for 211 item categories called item strata. Together the 211 item strata cover all consumer 

purchases. Examples of item strata are bananas, women’s dresses, and electricity. 

 Multiplying the number of areas by the number of item strata gives 8,018 (= 38 × 211) different area 

and item combinations for which price indexes need to be calculated. Separate price indexes are 

calculated for each one of these 8,018 area and item combinations. After all 8,018 of these basic-level

indexes are calculated, they are aggregated to form higher-level indexes, using expenditure estimates from 

the Consumer Expenditure Survey as their weights. Examples of higher-level geographic areas are the 

four regions (Northeast, Midwest, South, and West); and examples of higher-level item categories are the 

eight major groups (food & beverages, housing, apparel, transportation, medical care, education and 

communication, recreation, and other goods and services). The highest level of geographic aggregation is 

the U.S. city average, and the highest level of item aggregation is all items. 

 Variances are computed with a Stratified Random Groups Method, in which variances are computed 

separately for certain subsets of areas and items and are then combined to produce the variance of the 

entire area and item combination. Subsets of items are formed by the intersection of the item category 

with each of the eight major groups. 

 Let CPI(A,I,f,t) denote the index value where A = area, I = item category, f indicates that it is the fullsample value, and t = month; and let CPI(A,I,f,t-k) denote the value of the same index in month = t-k. In 

general, the upper-case letter A denotes a set of areas, such as the Northeast or Midwest region of the 

country; and the upper-case letter I denotes a higher-level item category, such as all items or all items less 

food and energy. Also let CPI(A,I,r,t) and CPI(A,I,r,t-k) be the corresponding index values for replicate 

= r. Most areas have two replicates, but some have more. Then, the full-sample k-month percent change

between months t-k and t is computed by dividing CPI(A,I,f,t) by CPI(A,I,f,t-k), subtracting 1, and 

multiplying by 100:

 Every index has a weight W(A,I,f) or W(A,I,r) associated with it, which is used to combine the index 

with other indexes to produce indexes for larger geographic areas and larger item categories. For 

example, the weights are used to combine all 8,018 basic-level indexes into higher-level indexes such as 

the U.S. city average all items index. The product of an index and its weight is called a cost weight, 

CW(A,I,r,t) = CPI(A,I,r,t) × W(A,I,r), and is an estimate of the total cost in area = A for consumption of 

item category = I in month = t. 

 For the Stratified Random Groups method used here, replicate percent changes are defined as follows: 

full sample cost weights are used for every geographic area within area = A except for one of the areas. In 

the omitted area, the full sample cost weight is replaced by a replicate cost weight. Let the lower case 

letter a denote one of the 38 basic-level areas included in area = A, and let the lower case letter i denote 

the intersection of item category = I with one of the 8 major groups. Then, the replicate percent change, 

for area = a, item subset = i, replicate = r, between months t-k and t, is computed as:

where S and N are the sets of all self-representing and non-self-representing areas in the CPI’s geographic 

sample, respectively; and A∩S and A∩N are the sets of all self-representing and non-self-representing 

areas within area = A. The number Ra is the number of replicates in area = a. 

Finally, the standard error of the percent change is computed by taking the square root of its variance: 

SE[ PC(A, I, f ,t,t − k)] = V[PC(A, I, f ,t,t − k)] .
