Science and Engineering Indicators (SEI)
Science and Engineering Indicators (SEI) provides a broad base of quantitative information on the U.S. and international
science and engineering enterprise. The data are "indicators." Indicators are quantitative representations that might
reasonably be thought to provide summary information bearing on the scope, quality, and vitality of the science and
engineering enterprise. The indicators reported in SEI are intended to contribute to an understanding of the current
environment and to inform the development of future policies.
SEI is factual and policy-neutral. It does not offer policy options and it does not make policy recommendations. SEI employs a
variety of presentational styles - tables, figures, narrative text, bulleted text, Web-based links, highlights, introductions,
conclusions, reference lists - to make the data accessible to readers with different information needs and different
SEI does not model the dynamics of the science and engineering enterprise, and it avoids strong claims about the significance
of the indicators it reports. SEI is used by readers who hold a variety of views about which indicators are most significant
for different purposes.
The Committee on Science and Engineering Indicators of the National Science Board oversees
the preparation, review and distribution of the biennial report, Science and Engineering Indicators. The Committee offers guidance
on content, organization, and presentation of data in the Indicators biennial report, the Digest
of Key Science and Engineering Indicators, and other related products; ensures that the SEI report addresses national issues
that concern stakeholders in the Federal Government and the U.S. science and engineering community; and keeps the Board informed
on trends and other data with significant policy implications identified during the production of SEI.
The Committee undertakes efforts to expand awareness and distribution of Indicators data for support of science and engineering policy
decisions at all levels of government and to inform the Federal government and the public of important data and trends reflecting the
condition of U.S. science and engineering.
The latest publication of the report is the Science and Engineering Indicators 2010.
