OFFICE OF THE DIRECTOR

A message from the Director, U.S. Census Bureau...
Very soon, we will be calling you to conduct the final interview for the Telephone Point of Purchase Survey
(TPOPS). In this interview, as in previous ones, you will be asked about a few purchases your household
may have made recently.
Your responses to the TPOPS help update the Consumer Price Index (CPI). The CPI is the most
important tool used to measure how fast prices are rising or declining. It directly affects wages, pensions,
and the cost of goods and services. To measure that change, the CPI monitors prices at the places where
you, and other people like you, shop. We identify those places through TPOPS.
Your participation in this survey is essential and is a service to your community; however, you may choose
to decline to answer any particular question. Federal law authorizes the collection of this information (Titles
13 and 29 of the United States Code), and the Confidential Information Protection and Statistical Efficiency
Act (CIPSEA) requires us to keep all information you provide strictly confidential, and to use that
information for statistical purposes only.
On the back of this letter are answers to questions you may have about TPOPS. If you would like more
information about the survey, types of questions you will be asked, or how to verify that the person calling
is a Census Bureau employee, please go to the TPOPS respondent website: www.bls.gov/tpops/.
Thank you again for your cooperation and continued participation over the past year in this important
survey. We appreciate your help.

FREQUENTLY ASKED QUESTIONS
Why is the Census Bureau calling me? I thought they only operated every ten years.
In addition to the decennial census, we collect data on a monthly basis. We collect these data to
provide up-to-date information on topics such as unemployment, spending, family income, housing,
manufacturing, and business activities to track the country’s economy.
What is this survey about?
The Telephone Point of Purchase Survey (TPOPS) provides information on the stores and businesses
where people shop and on the products they buy. This information updates the Consumer Price Index
(CPI) or the "cost of living index."
How will the information be used?
In order for the Bureau of Labor Statistics (BLS) to update the CPI, it is necessary to maintain an
up-to-date list of the stores and businesses where people shop. The U.S. Census Bureau conducts
TPOPS to provide statistical data needed to update this list. Your voluntary response is essential for
ensuring that this survey’s results are complete and accurate.
Why was I selected? Why not interview someone else?
Through a scientific sampling process, a phone number associated with your household was selected
randomly from a list of phone numbers. We did not select you personally. Your household represents
hundreds of other households in your region, so your participation in the survey is important.
What confidentiality protection do I have?
The confidentiality of the information you provide is assured to the full extent permitted by law in accordance
with the Privacy Act of 1974, and the Confidential Information Protection and Statistical Efficiency Act of 2002
(Title 5 of Public Law 107-347). The information you provide will only be used for statistical purposes.
What laws authorize you to conduct this survey?
The U.S. Office of Management and Budget has approved this survey and assigned it Control Number
1220-0044. Title 29, Section 2 of the United States Code (U.S.C.) authorizes the BLS to conduct household
studies. Title 13, Section 8 of the U.S.C. authorizes the Census Bureau to conduct surveys for other federal
agencies.
How long does the interview take?
You will be interviewed once a quarter for

quarters; the typical interview lasts between 10 and 20 minutes.

If you have any comments regarding the burden estimates or any other aspect of this survey, including
suggestions for reducing this burden, please send them to the Bureau of Labor Statistics, Division of
Consumer Price Index, Room 3615, 2 Massachusetts Avenue, NE, Washington, DC 20212. Additional
contact information can be found at www.bls.gov/tpops/.
