SCOPE OF SESTAT The SESTAT surveys include the NSCG, the National Survey of Recent College Graduates (NSRCG) , and the Survey of Doctorate Recipients (SDR)

From page 14... ...
All cases that qualify as scientists and engineers according to the SESTAT target population definition are integrated into a comprehensive database, the SESTAT integrated file, of all college-educated scientists and engineers in the United States. Because a person may be eligible for inclusion in more than one of the surveys, the National Science Foundation (NSF)

sample as selected from the census long-form records and do not include "carryover" sample units from the prior decade. There are two response rates shown for the later years of NSCG -- "conditional" response rates pertaining to the sample of respondents from previous cycles (including supplemental cases from the NSRCG)

science and engineering. The need for an adequate base of knowledge to be able to assess the effects of interventions and to better understand the complex system that educates and sustains a science and engineering workforce was recognized by a National Science Board (2003)

From page 19... ...
The effort included focus groups, invited papers, and a variety of panel and information meetings to obtain input from federal agencies, academic researchers, policy makers, and other stakeholders who use the SESTAT surveys. NSF also contacted a variety of people who were not users to ask why they were not using SESTAT data for their research or other purposes (personal communication, NSF staff)

or foreign degrees) in S&E jobs has been growing: it increased from 11.2 percent of the workforce in 1980 to 19.3 percent in 2000 (National Science Board, 2006, p.

From page 21... ...
However, because the census did not include information on respondents' field of degree, the NSCG had to include all college degree holders as its target population. The decision provided NSF with another valuable context in which to present the S&E workforce data -- a comparison of college graduates with and without science and engineering degrees.
|
From page 22... ...
The S&E-related group included the specified degrees and occupations: the degrees covered were those in health sciences, science and mathematics teacher education, and technology and technical fields; the occupations covered were health scientists, secondary teachers of science and mathematics, S&E managers, and technicians and technologists in science and engineering. For the NSCG, follow-up after the postcensal year was expanded to include people with S&E-related degrees or occupations.

From page 23... ...
Longitudinal Data All of the SESTAT surveys have been designed to produce crosssectional estimates for their individual target populations and for use in the SESTAT integrated database. However, some respondents in all three of the SESTAT surveys are treated as panel cases that are eligible for follow-up in subsequent years.
|
From page 24... ...
In addition, the selection of the decennial census as the frame spawned a longitudinal design that, in turn, provided stability to the estimates over time. The design enables analysts to track changes in status, such as career paths over time, but analysts need to have longitudinal weights to generate estimates in order to fully exploit the potential of the longitudinal character of the survey.

The amount of analysis that is possible with B&B data for detailed S&E fields is currently limited by small sample sizes. The 2000 cohort for the B&B survey numbered only about 10,000 sample cases; for details, see http://nces.ed.gov/programs/quarterly/Vol_5/5_3/5_2.asp#5 [accessed February 2008]
