INTRODUCTION OF NEW SAMPLE


ADVANCE MONTHLY SALES FOR RETAIL TRADE AND FOOD SERVICES


OCTOBER 2006

The U.S. Census Bureau of the Department of Commerce released revisions today to the monthly retail trade sales estimates for October 2006, September 2006, August 2006, October 2005, and September 2005. These revisions reflect the introduction of a new sample beginning with the restatement of the September and October 2006 estimates, and provide for a consistent time series between the old and new samples. Estimates adjusted for seasonal variation and holiday and trading-day differences were revised for October 2006, September 2006, August 2006, October 2005, and September 2005. Estimates not adjusted for seasonality were revised for October 2006 and September 2006.

October 2006: The advance estimate for October 2006 retail and food services sales, after adjustment for seasonal variation and holiday and trading-day differences, but not for price changes, were $363.8 billion, revised upward $0.2 billion from the original October 2006 sales estimate that was released on November 14, 2006.

September 2006: The preliminary estimate for September 2006 retail and food services sales, after adjustment for seasonal variation and holiday and trading-day differences, but not for price changes, were $365.2 billion, revised upward $0.7 billion or 0.2 percent from the preliminary September 2006 sales estimate that was released on November 14, 2006.

The Census Bureau conducts a major sample revision about once every five years to reflect the results of the latest economic census, ensure the sample remains representative of the retail and food service industries, and redistribute respondent burden for small and medium size companies. The sample for the advance estimates is a subset of the larger Monthly Retail Trade Survey (MRTS) sample that generates the preliminary and final estimates. In addition, the advance sample is reselected from the MRTS sample once in between major sample revisions. The previous MRTS sample was introduced with the March 2001 data month and the previous advance sample was introduced with the October 2003 data month.

The advance estimates are based on a subsample of the Census Bureau's full retail and food services sample. A stratified random sampling method is used to select approximately 5,000 retail and food services firms whose sales are then weighted and benchmarked to represent the complete universe of over three million retail and food services firms. Responding firms account for approximately 65% of the MARTS dollar volume estimate. For an explanation of the measures of sampling variability included in this report, please see the Reliability of Estimates section on the last page of this publication.

Survey Description

The U.S. Census Bureau conducts the Advance Monthly Retail Trade and Food Services Survey (MARTS) to provide an early estimate of 
monthly sales by kind of business for retail and food service firms located in the United States.  Each month, questionnaires 
are mailed to a probability sample of approximately 5,000 employer firms selected from the larger Monthly Retail Trade Survey 
(MRTS).  Firms responding to MARTS account for approximately 65% of the total national sales estimate.  Advance sales estimates 
are computed using a link relative estimator.  The change in sales from the previous month is estimated using only units that 
have reported data for both the current and previous month.  There is no imputation or adjustment for nonrespondents in MARTS.  
The total sales estimate is derived by multiplying this ratio by the preliminary sales estimate for the previous month (derived 
from the larger MRTS sample).  Detailed industry estimates are summed to derive total estimates at broad industry levels.  
The monthly estimates are adjusted using annual survey estimates and for seasonal variation and holiday and trading-day 
differences.  Additional information on MARTS and MRTS can be found on the Census Bureau website at:  
http://www.census.gov/mrts/www/mrts.html.


Reliability of Estimates

Because the estimates presented in this report are based on a sample survey, they contain sampling error 
and nonsampling error.

Sampling error is the difference between the estimate and the result that would be obtained from a complete 
enumeration of the sampling frame conducted under the same survey conditions.  This error occurs
because only a subset of the entire sampling frame is measured in a sample survey.  Standard errors and 
coefficients of variation (CV), as given in Table 3 of this report, are estimated measures of
sampling variation.

The margin of sampling error, as used on page 1, gives a range about the estimate which is 90-percent 
confidence interval.  If, for example, the percent change estimate is +1.2 percent and its
estimated standard error is 0.9 percent, then the margin of sampling error is ±1.65 x 0.9 percent or 
±1.5 percent, and the 90 percent confidence interval is -0.3 percent to +2.7 percent.     

If the interval contains 0, then one does not have sufficient statistical evidence to conclude at the 90 percent 
confidence level that the change is different from zero and therefore the change is not statistically 
significant. Estimated changes shown in the text are statistically significant unless otherwise noted. 
For a monthly total, the median estimated coefficient of variation is given.  The resulting confidence interval 
is the estimated value ±1.65 x CV x (the estimated monthly total).  The Census Bureau recommends that individuals 
using estimates in this report incorporate this information into their analyses, as sampling error could affect 
the conclusions drawn from the estimates.  

Nonsampling error encompasses all other factors that contribute to the total error of a sample survey 
estimate.  This type of error can occur because of nonresponse, insufficient coverage of the
universe of retail businesses, mistakes in the recording and coding of data, and other errors of collection, 
response, coverage, or processing.  Although nonsampling error is not measured directly, the Census Bureau 
employs quality control procedures throughout the process to minimize this type of error.  


(1) Estimated measures of sampling variability are based on estimates not adjusted for seasonal variation, or holiday, or trading-day differences. Medians are based on estimates for the most recent 12 months.

(2) These columns provide measures of the difference between the advance-to-preliminary and preliminary-to-final estimates of month-to-month change for the same pair of months as measured by the Advance sample and MRTS sample. The average and median differences are based on estimates for the most recent 12 months.
