SESTAT (Scientists and Engineers Statistical Data System) is a table-generation tool for data on the education and employment of the college-educated U.S. science and engineering workforce. These data are integrated in SESTAT from three NSF-sponsored surveys:

  • National Survey of College Graduates
  • National Survey of Recent College Graduates
  • Survey of Doctorate Recipients
Data cover 1993 to present.


WebCASPAR (Integrated Science and Engineering Resources Data System) is a table-generation tool for data on academic science and engineering resources at U.S. academic institutions. These data are collected by six NSF-sponsored surveys and four surveys sponsored by the National Center for Education Statistics (NCES). Depending on the survey, data cover 1966 to present.

NSF surveys
  • Survey of Earned Doctorates
  • Survey of Federal Funds for R&D
  • Survey of Federal Science and Engineering Support to Universities, Colleges, and Nonprofit Institutions
  • Higher Education R&D Survey
  • Survey of Science and Engineering Research Facilities
  • Survey of Graduate Students and Postdoctorates in Science and Engineering
NCES surveys
  • Integrated Postsecondary Education Data System (IPEDS) Completions Survey
  • IPEDS Enrollment Survey
  • IPEDS Institutional Characteristics Survey Tuition Data
  • IPEDS Salaries, Tenure, and Fringe Benefits Survey

SED Tabulation Engine

The SED Tabulation Engine is a table-generation tool for data on selected variables in the Survey of Earned Doctorates and complement data in WebCASPAR. The tabulation engine includes a disclosure control mechanism that prevents the release of confidential data by protecting the identity of respondents when sex, citizenship, race, and ethnicity variables are used. Data cover 2006 to present.

Public-Use Data Files

Public-use data files are microdata files and documentation available for public use and do not contain any individually identifiable information. Public-use data files are available for the following surveys:

All public-use data files are available in SAS format. Data files from the GSS are also available in Excel format. Data for SESTAT surveys cover 1993 to present.

Restricted Access Files

Under certain conditions, restricted access microdata files may be obtained under a license agreement for the following:

  • National Survey of College Graduates
  • Survey of Doctorate Recipients
  • Survey of Earned Doctorates
  • SESTAT Integrated File

The National Center for Science and Engineering Statistics (NCSES) of the National Science Foundation (NSF) is bound by the Privacy Act of 1974, as amended, the NSF Act of 1950, as amended, and the Confidential Information Protection and Statistical Efficiency Act of 2002, Title V, all of which provide for the security and privacy of personally identifiable statistical data.

In some cases, NCSES may provide special tabulations or summary data to meet the specific need for data rather than granting restricted access to microdata files. When granted, restricted access via a license agreement may permit the researcher or data user access to the data files at the researcher's academic institution or via secured, remote access to the NSF-NORC data enclave.

Data for the restricted access files cover 2003 to present.

Researchers interested in using NCSES restricted data files, in information on NSF confidentiality and privacy policies, or in licensing procedures, may contact the NCSES data use coordinator.

Academic Institution Profiles

Academic Institution Profiles is an interactive website providing access to selected data on the number of earned doctorates, number of graduate students and postdoctorates in science and engineering, total federal obligations, and total R&D expenditures by individual U.S. academic institutions. Academic Institution Profiles also includes rankings of institutions by four selected variables. Data come from four NCSES surveys: the Higher Education R&D Survey; the Survey of Earned Doctorates; the Survey of Federal Science and Engineering Support to Universities, Colleges and Nonprofit Institutions; and the Survey of Graduate Students and Postdoctorates in Science and Engineering. All data are available for download. Data cover the most recent 10 years.


IRIS (Industrial Research and Development Information System) provides access to more than 2,500 historical detailed statistical tables on industrial R&D from the Survey of Industrial Research and Development. Data cover R&D performed within the United States by U.S.- or foreign-owned companies classified by the Standard Industrial Classification (SIC) coding scheme from 1952 to 1998 and by the North American Industrial Classification System (NAICS) for 1999 to 2007. Data cover 1953 to 2007.

State Profiles

State Profiles is an interactive website providing access to state-level data on science and engineering personnel and finances and state rankings. State Profiles displays up to 10 state profiles of the user’s choice. Data are available from NSF-sponsored surveys on employed science, engineering, or health (SEH) doctorate holders; science and engineering (S&E) doctorates awarded, including by major S&E fields; SEH graduate students and postdoctorates; federal R&D obligations by agency and performer; total and industrial R&D expenditures; and academic R&D expenditures, including by major S&E fields. Data available from other sources include population, civilian labor force, per capita personal income, federal expenditures, patents, small business innovation research awards, and gross domestic product. All data are available for download. Data cover 2003 to present.
