Science and Engineering Indicators, published by the National Science Board, provides a broad base of quantitative information on the U.S. and international science and engineering enterprise. Science and Engineering Indicators (SEI) is first and foremost a volume of record comprising the major high-quality quantitative data on the U.S. and international science and engineering enterprise. 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 information-processing preferences.

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.
