Statement of Commitment to Scientific Integrity by Principal Statistical Agencies
Our Nation relies on the flow of objective, credible statistics to support the decisions of governments, businesses, households, and other organizations. Any loss of trust in the integrity of the Federal statistical system and its products can foster uncertainty about the validity of measures our Nation uses to monitor and assess performance and progress.
Federal statistical agencies (or units) whose principal function is the collection, analysis, and dissemination of information for statistical purposes have set for themselves a high standard of scientific integrity. The following agencies are designated as "principal statistical agencies[ 1]":
These agencies embrace a common set of professional standards and operational practices designed to ensure the quality, integrity and credibility of their statistical activities. Implementation of these professional standards involves a wide range of managerial and technical challenges.
Principles and Practices of Statistical Agencies
To address these challenges, the National Research Council of the National Academies (NRC) has developed practical guidance in its publication, Principles and Practices for a Federal Statistical Agency[ 2]
The principal statistical agencies use this volume to guide their strategic planning, daily operations, and interactions with stakeholders. The principal statistical agencies embrace the four fundamental principles articulated in the Fourth Edition:
Actual and perceived violations of any of these principles undermine the scientific integrity of, and public confidence in, the data produced by principal statistical agencies. Of special note is the emphasis that the NRC publication places on the impartiality and independence of each statistical agency. The NRC discussion of independence includes the following.
The principal statistical agencies also subscribe to the 11 practices identified by the NRC as critically important in the application of these principles:
All of these practices are important to achieving and safeguarding scientific integrity. Implementation details of these practices vary across agencies.
Statistical Policy Directives and Standards
The Principles and Practices are closely related to Statistical Policy Directives and other standards issued by the Office of Management and Budget (OMB) in its role as coordinator of the Federal statistical system (44 U.S.C. 3504(e). Specifically, OMB's directives and standards are designed to preserve and enhance the objectivity, utility, and transparency, in fact and in perception, of the statistical products themselves and the processes used to release and disseminate them. Examples include:
Information Quality Guidelines
The Principles and Practices are also related to the Information Quality Act[ 6], which requires OMB and all other Federal agencies to maximize the quality, objectivity, utility, and integrity of information, including statistical information, provided to the public. Through the adoption and implementation of the Government-wide Information Quality Guidelines[ 7], each statistical agency:
Using Best Scientific Methods to Ensure Data Quality and Integrity
Finally, scientific methods play a critical role in maximizing the quality, objectivity, and credibility of information collected and disseminated by the principal statistical agencies. Examples of the application of scientific methods include probability sampling designed to avoid biased samples and randomized assignment for assessing the impacts of alternative protocols or question wording. Measures need to be valid and reproducible, and interpreting variations in these measures across data sources requires scientific knowledge of their properties. Combining data from disparate sources, such as surveys and administrative records, is increasingly important given the growing reluctance of respondents to provide data in Federal data collection efforts. These efforts require statistical modeling, as does the provision of statistics on small areas where direct estimates from surveys may be subject to large sampling errors. The procedures, equations, and assumptions, which define these models, must be publicly available to ensure that the information is presented in an accurate, clear, complete, and unbiased manner. Moreover, Federal statistical agencies apply complex statistical methods to the information that is publicly released to protect the confidentiality of data about respondents to Federal surveys.
Methodological improvements and rigorous approaches to data collection and analysis require the application of scientific methods. Computer scientists, demographers, economists, geographers, mathematicians, survey statisticians, and other scientists are needed for producing high quality, objective statistics from surveys or administrative data. Subject area experts, such as epidemiologists and engineers, are also needed to maximize data quality. Research and methodological innovation are required to continuously improve the quality and scope of our data products while protecting privacy and ensuring confidentiality. All of the above mentioned factors are critically important to ensuring the credibility of Federal statistical agencies.
We reaffirm our commitment to maintaining the highest level of scientific integrity in producing official statistics. Together, the Principles and Practices, Statistical Policy Directives and Standards, and Information Quality Guidelines form the foundation for achieving and maintaining scientific integrity within and among the principal statistical agencies.
