Overview (2006 survey cycle) ![Top of Page.](https://webarchive.library.unt.edu/eot2008/20081106055340im_/http://nsf.gov/statistics/graphics/uparrow6.gif)
The National Science Foundation regularly collects nationally representative data about public attitudes toward and understanding of science and technology (S&T). NSF has changed its means of collecting these data over time. Until 2001 data were collected by telephone though a single-purpose Survey of Public Attitudes Toward and Understanding of Science and Technology. In 2004 NSF placed S&T questions on the University of Michigan Survey of Consumer Attitudes, also conducted by telephone. The Consumer Attitudes survey included questions on topics other than S&T. For the 2006 data collection, Science Resources Statistics (SRS), a division of NSF, funded an S&T module on the biennial General Social Survey (GSS) (http://gss.norc.org/). The GSS is a nationally representative, face-to-face survey covering a broad range of behavior and attitudes conducted by the National Opinion Research Center (NORC) at the University of Chicago.
a. Purpose
Researchers and government officials—particularly those responsible for scientific research and education—use data collected from the U.S. adult population to monitor public knowledge of and attitudes toward a variety of science-related issues and topics. The GSS S&T module combines questions that have been asked on previous SRS surveys with new questions, many of which probe different aspects of the cultural authority of science. Data on the U.S. public's views and knowledge of S&T have been collected for NSF since 1972, and time trends beginning with 1979 can be constructed for many variables. Other countries have conducted similar surveys, facilitating international comparisons.
b. Respondents
Randomly selected English or Spanish speaking persons age 18 or over, living in noninstitutional arrangements within the United States, March to August 2006.
c. Key variables
The 2006 GSS S&T module included questions on the following topics:
-
How information about S&T is obtained
- S&T knowledge
- Attitudes toward science-related issues
- Trust in scientists, business and religious leaders, and elected officials regarding science-related issues
The 2006 GSS also collected a wealth of demographic, behavioral, and attitudinal data that can be used in analysis of the data collected by the SRS-sponsored S&T module.
2. Survey Design ![Top of Page.](https://webarchive.library.unt.edu/eot2008/20081106055340im_/http://nsf.gov/statistics/graphics/uparrow6.gif)
a. Target population
The 2006 GSS target population was all English or Spanish speaking persons age 18 or over living in noninstitutional arrangements in the United States. (See http://gss.norc.org/ for more detail.)
b. Sample frame and design
The 2006 GSS was a national area probability sample of noninstitutionalized adults. The sampling frame was based on the 2000 Census. The 2006 GSS S&T module questions were asked of approximately 2,000 randomly selected adults age 18 or older residing in the United States.
c. Data collection techniques
GSS interviews mainly are conducted face-to-face. S&T module questions were administered to 1,864 people in 2006. Within this group, some questions were asked of all respondents and some were asked of half the respondents. A similar module will be included in the 2008 GSS.
The 2006 GSS was the first to have a Spanish language version, using bilingual interviewers. For 2006 core content was fielded in Spanish, including science-related items on national spending and confidence in institutions, but S&T module questions were not. In future years all sections are planned to be translated to and administered in Spanish.
d. Estimation techniques
Access to the GSS data and documentation are available through a variety of sources on the Internet. The data set includes weights. See http://gss.norc.org/ for more detail.
3. Survey Quality Measures ![Top of Page.](https://webarchive.library.unt.edu/eot2008/20081106055340im_/http://nsf.gov/statistics/graphics/uparrow6.gif)
a. Sampling variability
The 2006 GSS is a full probability sample. Because of survey nonresponse, sampling variation, and various other factors, the GSS sample does deviate from known population figures for some variables. The GSS does not calculate any post-stratification weights to adjust for such differences. See http://gss.norc.org/ for more detail.
b. Coverage
The 2006 GSS likely underrepresented males. See http://gss.norc.org/ for more detail.
c. Nonresponse
The overall response rate for the 2006 GSS was 71%. See http://www.norc.org/Hidden/GSS+Facts.htm for more detail.
d. Measurement
The 2006 GSS was the 26th fielding of the survey. The questionnaire contained a standard core of demographic and attitudinal variables, plus certain topics of special interest called "topical modules." The GSS incorporates methodological experiments each year, involving question wording, context effects, uses of different types of responses, random probes, and other assessments of validity and reliability.
Since 1985 the GSS has taken part in the International Social Survey Program (ISSP), a consortium of social scientists from 41 countries around the world. The ISSP asks an identical battery of questions in all countries; the U.S. version of these questions is incorporated into the GSS. See http://gss.norc.org/ for more detail.
4. Trend Data ![Top of Page.](https://webarchive.library.unt.edu/eot2008/20081106055340im_/http://nsf.gov/statistics/graphics/uparrow6.gif)
Science and Engineering Indicators has included information on public attitudes toward science and technology in every biennial edition since 1972 (except 1978). A significant restructuring of the survey was undertaken in 1979, which has provided the framework for subsequent surveys. Time trends for many of the variables can be constructed for the years 1979, 1981, 1985, 1988, 1990, 1992, 1995, 1997, 1999, 2001, 2004, and 2006.
