This report provides statistical information about the participation of women, minorities, and persons with disabilities in science and engineering education and employment. Its primary purpose is to serve as an information source. It offers no endorsement of or recommendations about policies or programs. National Science Foundation reporting on this topic is mandated by the Science and Engineering Equal Opportunities Act (Public Law 96-516). This digest, new for 2011, highlights key statistics drawn from the wide variety of data sources used to provide this information. Data and figures in this digest are organized into six topical areas--enrollment, field of degree, employment status, occupation, academic employment, and persons with disabilities. Surveys conducted by the Science Resources Statistics division of the National Science Foundation provided a large portion of the data used in this report. During the report's production, the America COMPETES Reauthorization Act of 2010 was signed into law. Section 505 of the bill renames the Division of Science Resources Statistics as the National Center for Science and Engineering Statistics (NCSES). The new name signals the central role of NCSES in the collection, interpretation, analysis, and dissemination of objective data on the science and engineering enterprise. Furthermore, the technical notes for this report provide information on specific data sources, including the survey population, data collection procedures, and sampling errors. This digest includes data on people with degrees in science, engineering, and health fields, constituted in this report by the following fields: astronomy, chemistry, physics, atmospheric sciences, earth sciences, oceanography, mathematics and statistics, computer sciences, agricultural sciences, biological sciences, psychology, social sciences, engineering, medical sciences, and other life sciences. Glossary and a list of online resources are also included.
