How a Question Becomes Part of the
American Community Survey
December 2023
The U.S. Census Bureau must balance the information
needs of a growing, changing nation with respect for
the privacy and time of the American public.
Additionally in conjunction with the Department of
Commerce’s Office of Chief Counsel, the Census Bureau
does a periodic validation of the uses of all questions to
ensure there is a legal basis for them.
Adding a question or making a change to the American
Community Survey (ACS) involves extensive testing,
review, and evaluation over a 5-year period. This ensures ments in testing methods, availability of resources, and
the change is necessary and will produce quality, useful
information for the nation.

question.
The requesting agency must show that it needs frequent data at
small geographies, that no other sources of information are
available, and that its mission would be compromised if the
question was not added or changed.
2. The Office of Management and Budget (OMB) and
Census Bureau decide whether the change has merit.
Legal staff review the proposal to determine if it meets the
legislative requirements. The Census Bureau and OMB decide
whether the request merits further consideration, in consultation
with the Interagency Council on Statistical Policy Subcommitee on
the ACS.
3. Create wording options.
Subject matter experts identify ways to ask each question using
different words and phrases.
4. Test different ways to ask the question.
The Census Bureau solicits public comment and OMB approval for
the field test. Census Bureau staff finalize the wording for the test,
create instruments to field the test, develop the systems to
process the data collected, and conduct the test. Then, they
tabulate and analyze the results and provide them to the federal
agency that requested the change.
6. Census Bureau solicits public comment; OMB
approves or rejects change.
The Census Bureau and requesting federal agency review the
research results and decide whether to recommend implementa-
tion of the new or changed survey question. The Census Bureau
solicits public comment through a Federal Register Notice to
inform a final decision in consultation with the OMB and the
Interagency Council on Statistical Policy Subcommittee on the
ACS.
Note: The Paperwork Reduction Act requires OMB approval of data collections that
would impose a burden on the American public. It also requires a public comment
period via the Federal Register.
The Census Bureau conducts cognitive interviews to gauge which
wording is best understood and produces the most accurate
results.
Subject matter experts review the cognitive testing results and
recommend the version for field testing.
7. Census Bureau implements the change.
If approved by the OMB, the Census Bureau prepares to imple-
ment the change by updating systems, questionnaires, and
materials. Implementation takes effect at the start of a calendar
year.
