Administrative Data at the U.S. Census Bureau


The U.S. Census Bureau  is a federal statistical agency that
is tasked with producing statistics on demographic and
economic  characteristics across the United States and, in
some  instances, its territories. The Census Bureau collects
data using several methods, including surveying
respondents directly and using administrative data (also
referred to as administrative records). These data are then
analyzed to produce federal statistics.

Administrative data are data that were not generally
collected for the purposes of producing federal statistics.
Instead, these data are collected and maintained by federal
agencies in order to administer (or run) programs and
provide services to the public.

The Census  Bureau has increasingly used administrative
data to reduce respondent burden and data-collection costs,
create new data products, and increase the research
potential of census data.

Members   of Congress may have an interest in how the
Census Bureau  uses administrative data as it pertains to cost
savings, quality of data and its fitness for purpose, and
confidentiality of the administrative data sources.

Administrative Data
Administrative data are generally not collected through
surveys and are produced for nonstatistical purposes.
Rather, administrative data are collected to support
administering some kind of program or service, such as
mailing addresses linked to individuals for the purpose of
mail delivery by the United States Postal Service (USPS).

Other examples of administrative data include but are not
limited to individual data, such as social security data and
income  tax return data; business identifying information,
such as descriptions of operating, financial, ownership, and
other characteristics; and address data, such as latitude or
longitude points, telephone numbers, and street addresses.

Authority to Use Administrative Data
The Census  Bureau is authorized under Title 13, Section 6,
of the U.S. Code to acquire and use administrative data
from other federal departments, agencies, or establishments
as well as private persons and agencies when these data
are consistent with the kind, timeliness, quality, and scope
of statistics required.

Additionally, the Privacy Act of 1974 (5 U.S.C.
§552a(b)(4)) permits federal agencies to share records
concerning a U.S. citizen or lawful resident with the Census
Bureau  solely for statistical purposes.


In 2014, the Office of Management and Budget (OMB)
established guidance for federal agencies to follow when
working with administrative data for statistical purposes.

Statistical   Quality Standards for Using
Administrative Data
The latest release of the Census Bureau's statistical quality
standards provides standards the agency follows when
acquiring and using administrative data. These
requirements are broadly that the Census Bureau

    1.  follow provisions of federal laws
        throughout the process of acquiring,
        using, and disposing of administrative
        data;
    2.  develop a study plan to evaluate the
        integrity and reliability of the
        administrative data provider;
    3.  ensure the acquired administrative data
        meet  specified data-use agreements;
    4.  evaluate the quality of the administrative
        data by calculating missing data rates
        within the records, calculating coverage
        rates, and evaluating the accuracy of the
        records; and
    5.  produce  documentation needed to
        replicate and evaluate projects that use
        administrative data, such as research
        reports to guide decisions and
        descriptions of processes.
Additionally, the Census Bureau established some guiding
principles to follow when considering using administrative
data in the American Community  Survey (ACS), one of the
bureau's largest surveys, in a 2018 report. Below is a
selection of those principles.

for Using Administrative  Data  for Enhancing the ACS

  Requirement                 Description


Coverage



Quality


How  comprehensive is the coverage of the
administrative data with respect to
geographies and population subgroups?
What  is sufficient data quality for the
published estimates? Do the administrative
data meet these quality requirements?


Conceptual      Do the administrative data correspond to
Alignment       the concept the ACS currently intends to
                measure?


Temporal
Alignment


Do the administrative data correspond to
the time period referenced in the ACS?
