Variance Estimates for Price Changes in the Import and Export

Price Indexes January–December 2022 

Each month, the International Price Program (IPP) at the Bureau of Labor Statistics (BLS) collects roughly 18,300 

prices for a representative sample of goods traded by approximately 3,200 importers and exporters to and from the 

United States. The prices represent the market basket of imports and exports. The sample of import and export 

transaction prices is drawn from the complete universe of all items traded during a calendar year as measured by 

the Census Bureau. Sampling variability results whenever a sample is used rather than the complete universe.

Variance Results

As of 2019, variance calculation is expanded to cover all published import and export price indexes spanning all 12

months for merchandise goods trade sampled items. Variances are not calculated for locality of origin, locality of 

destination and terms of trade price indexes covering goods, nor for services price indexes. The variance results by 

year measure the absolute median 1-, 3-, and 12-month percent changes for all published import and export 

indexes along with the median standard error for those estimates. Tables are broken out by classification system

down to the 5-digit level of detail for the Bureau of Economic Analysis (BEA) End-Use Classification System, the 6-

digit level of detail for the North American Industrial Classification System (NAICS), and the 4-digit index level of 

detail for the Harmonized Classification System. 

The standard error, the square root of the estimated variance, is a common measure used to derive confidence 

intervals for percent changes in the import and export price indexes. Confidence intervals can be used to determine

if an index change is significantly different from zero. 

Take for example the median absolute 1-month percent change of 0.9 percent for All Commodities import prices, as 

seen in Table 1. The standard error for imports on a 1-month basis was 0.17. So, deriving a confidence interval plus 

or minus two standard errors from the point estimate, assuming a normal distribution, the true change would most 

likely be 0.9 percent plus or minus 0.34, or between 0.56 percent and 1.24 percent. 

Sources of Error

There are different types of errors introduced when calculating the estimates of average price changes for imports 

and exports published by the Bureau of Labor Statistics. There are two sources of error: sampling and nonsampling

error. Sampling error, reported in the tables of this report, is the error resulting from drawing a sample of imported 

and exported items to and from the United States, rather than using the entire universe of trade.

Nonsampling error can take a number of different forms. One form is misspecification error, which takes place if the 

universe of data from which the sample is being drawn does not correctly measure the actual population. For import 

and export prices indexes, this type of error could result if there are mistakes in the trade dollar value statistics 

measured by the Census Bureau. A second type of nonsampling error is nonresponse error. Each month, a subset of 

the items sampled by the Bureau of Labor Statistics does not have prices reported. This type of error results if the 

respondents and nonrespondents do not represent a similar cross section of the total universe. Another form of 

nonsampling error can be introduced from misreported prices, a possibility regardless of whether deriving the

indexes from a sample or from the complete universe of data. 

One issue when deriving an estimate from a sample is the potential trade-off between variance and bias. Variance is

a measure of how much the estimates derived from numerous samples differ from the true value of the estimate.

Bias results if the expected value of the estimate is either higher or lower than the true value of what is being

estimated. An estimate could have a high sampling variance and still be unbiased if the expected value of the

estimate is equal to the true value. Likewise, an estimate may have small variation over numerous samples, yet be

biased if the expected value of the estimate deviates from the true value. 

The Bureau of Labor Statistics strives to minimize both sampling and nonsampling error as much as possible. 

Sampling error is reduced by maintaining as many prices as possible to support an index given resource and 

1
company burden constraints. Nonsampling error is reduced by subjecting the data to careful review using 

automated checks and a staff of professional economists, as well as by employing methods to estimate missing 

observations. 

Sampling in the International Price Program

Trade into and out of the United States is highly regulated and therefore highly documented. This allows the IPP to 

sample from a fairly complete and detailed frame. U.S. Customs and Border Protection provides the sampling frame 

for import merchandise, while the export merchandise frame is created from a combination of data collected by the 

Canada Border Services Agency, for exports to Canada, and from the Census Bureau for exports to the rest of the 

world. 

The import and export merchandise universes are divided into two panels each, with each product-based panel 

representing approximately half of the trade dollar value for its respective universe. One import and one export 

panel are sampled each year, resulting in a fully sampled universe every 2 years. Each panel is sampled using a 3-

stage sample design. The first stage independently selects establishments within product-based sampling strata 

using systematic probability proportional to size, where the measure of size is the total trade dollar value for 

establishments within the sampling stratum. The second stage selects more highly detailed product categories, 

known as classification groups, within each establishment–stratum combination selected during the first stage using 

the technique of systematic probability proportional to size with replacement. The final stage of sampling, which 

results in a unique item to price, occurs in the field and is a random selection technique with the probability of 

selection proportionate to field-collected trade estimates.

Index Calculations

IPP calculates its indexes using a modified Laspeyres formula. Rather than calculate indexes relative to a base 

period, the IPP indexes are calculated relative to the previous period and are theoretically chained to the reweight 

period. For this reason, IPP’s indexes can be considered chained Laspeyres indexes. Explicitly, the index formula for 

the modified chained Laspeyres is derived from the classic formula as follows:

LLLLLLtt = �

∑ ppii,ttqqii,0ii

∑ ppii,0qqii,0ii

� (100) = �

∑ ppii,tt

ppii,0 ii ppii,0qqii,0

∑ ppii,0qqii,0ii

� (100) = �

∑ rrii,ttwwii,0ii

∑ wwii,0ii

� (100) = � ∑ rrii,ttwwii,0ii

∑ii rrii,tt−1wwii,0

� �∑ii rrii,tt−1wwii,0

∑ wwii,0ii

� (100) =

� ∑ rrii,ttwwii,0ii

∑ii rrii,tt−1wwii,0

� (LLLLLLtt−1) = (SS tt)(LLLLLLtt−1), 

where 

LLLLLLtt = the long term relative of a collection of items at time tt; 

ppii,tt = price of item ii at time tt; 

qqii,0 = quantity of item ii in base period 0;

wwii,0 = ppii,0qqii,0, or the total revenue generated by item ii in base period 0; 

rrii,tt = ppii,tt/ppii,0, or the long term relative of item ii in period tt; and 

SS tt = ∑ rrii,ttwwii,0ii

∑ii rrii,tt−1wwii,0

, or the short term relative of a collection of items at time tt. 

Depending on the level of aggregation, the weights used during index aggregation are either trade dollar-based or 

probability-based. At the lowest level of aggregation, items are weighted by probability-based weights calculated 

monthly corresponding to detailed categories within establishments.

These weighted-item price relatives are combined across establishments and aggregated to the lowest level stratum 

indexes as

2
PPh,tt =

∑ ∑ ∑ wwkk,ttwwjj,ttwwii,tt�

ppii,tt

ppii,0 iijjkk �

∑ ∑ ∑iijjkk wwkk,ttwwjj,ttwwii,tt

, 

where

PPh,tt = the price index for lowest level stratum h, at time tt;

wwkk,tt = the weight of detailed product category kk, within stratum h; 

wwjj,tt = the weight of establishment jj, within detailed product category kk; 

wi,t = the weight of item ii, within establishment jj and detailed product category kk; and

ppii,tt

ppii,0

= the price relative of item ii, from period tt, to base period 0.

The weights used for these lowest level stratum indexes are derived from sampling frame trade dollar values, 

divided by the corresponding probabilities of selection determined by the sample design.

At the next level of aggregation, child strata-level indexes are aggregated to their corresponding parent stratumlevel indexes. A child stratum index is simply one level of aggregation less than its parent stratum index. The 

weights used for this aggregation are based on Census Bureau trade dollar values for the base period.

The aggregation formula for these upper index levels is

PPHH,tt = ∑h wwh,ttPPh,tt

∑ wwh,tth

, 

where

PPHH,tt = the price index at period tt, for upper level index HH; 

wwh,tt = the weight at period tt, for child index h; and

PPh,tt = the price index at period tt, for child index h. 

Replication and Variance Estimation

A modified bootstrap method, applying rescaled sampling weights, is used to produce 150 replicate index set 

estimates from 150 simulated item set samples. Item set replicates are constructed according to IPP’s 3-stage 

sample design. At both of the first two stages of sampling, it is possible for a selection to be either a certainty 

selection (i.e. the probability of selection is greater than the iteratively calculated sampling interval) or a probability 

selection. The replicate resampling method takes this into consideration by first partitioning the selected items 

within each sampling stratum mm into those items that resulted from certainty establishment selections and those 

items resulting from probability establishment selections. The item set resulting from establishment certainty 

selections is further partitioned into two item sets: sampling classification group certainty selections and sampling 

classification group probability selections. Thus, the set of all sampled items SS is the union of these three partitions 

over all sampling strata mm; 

SS = � SSmm

NN

mm=1

= � ��SSmmpp

3

pp=1 �

NN

mm=1

where NN is the number of sampling strata, pp ∈ {1,2,3}, with pp = 1 for items selected from probability 

establishments, pp = 2 for items selected from probability sampling classification groups within certainty 

establishments, and pp = 3 for items selected from certainty sampling classification groups within certainty 

establishments.

Each bootstrap sampling, bb, selects nnmmpp

bb units within each partition of each sampling stratum as follows:

nnmmpp

bb = �

nnmmpp − 1 nnmmpp

> 1

1 nnmmpp

= 1�,

where nnmmpp

bb is the number of units originally sampled in partition pp of sampling stratum mm. 

3
Bootstrap item weights are then calculated as

wwmmpp,

jj,ii

bb = �

wwmmpp,jj,ii �

nnmmpp

bb + 1

nnmmpp

bb � ddmmpp,jj

bb for nnmmpp > 1

wwmmpp,jj,ii for nnmmpp = 1�

where

wwmmpp,jj,ii

bb = the bbtth replicate item weight for item ii, within establishment jj and sampling stratum partition mmpp; 

wwmmpp,

jj,ii = the standard item weight for item ii, within establishment jj and sampling stratum partition mmpp; and

ddmmpp,jj

bb = the number of times establishment jj, within partition pp of sampling stratum mm, is selected in bootstrap 

sample bb. 

In the rare instances that nnmmpp = 1, a simple random sample of items within that establishment is selected. If only 

one item exists under this establishment singleton, that item is chosen with certainty.

For each of the 150 bootstrap samples, chained indexes of the desired length are calculated at all levels of 

aggregation using these modified item weights, original probabilities of selection, trade dollar values, and collected 

price data. For variance estimates, the variance is calculated across replicate percent change values for all published 

indexes as ννBB = 1

150 ∑ �θθ�

bb − θθ��

2 150

bb=1 where θθ� is the full sample estimate.
