General Social Survey

1. General Social Survey

The **General Social Survey (GSS)** is a sociological survey used to monitor societal change and study the attitudes and characteristics of the American population. Conducted by the NORC (National Opinion Research Center) at the University of Chicago, the GSS has been running since 1972 (with preliminary surveys dating back to 1957), making it an invaluable resource for researchers in a wide range of disciplines, including sociology, political science, psychology, and economics. It’s considered one of the most important and methodologically rigorous social science surveys available. This article provides a comprehensive overview of the GSS, its history, methodology, data content, uses, and limitations, geared towards newcomers to social science research.

History and Development

The origins of the GSS lie in the need for a regular, reliable source of data on social trends in the United States. Prior to the GSS, data collection was often ad hoc, making it difficult to track changes over time. The initial impetus came from researchers who wanted to replicate and extend the findings of the earlier election studies, which focused primarily on political attitudes and voting behavior.

The first true GSS was conducted in 1972, modeled after the British Social Attitudes survey. It was designed to be a nationally representative, face-to-face interview survey. Key figures in its development included Robert B. Clogg and Stanley Presser, who established the core principles of the survey’s design and administration. The GSS initially ran every two years, but, due to funding constraints, transitioned to a five-year cycle beginning in 2006. However, supplementary surveys, like the GSS Topical Modules, are conducted more frequently on specific issues. The continuous evolution of the GSS reflects the changing needs of the social science research community and advancements in survey methodology. The GSS has also seen adaptations to incorporate new technologies, such as web-based data collection, while maintaining its commitment to high-quality data.

Methodology

The GSS employs a complex sampling design to ensure that its results are representative of the US adult population (age 18 and over). Understanding this methodology is crucial for interpreting the data correctly.

• **Sampling Frame:** The GSS utilizes a multistage stratified sample. Initially, the United States is divided into geographic strata (typically counties). Within each stratum, dwelling units are selected using a probability-proportional-to-size (PPS) method. This means that areas with more people have a higher chance of being selected.
• **Household Selection:** Within selected areas, households are randomly selected. Not all households are eligible, as institutional settings (e.g., prisons, nursing homes) are excluded.
• **Respondent Selection:** Within eligible households, one adult (18 or older) is randomly selected to participate. The GSS uses a "next-birthday" method to select the respondent, minimizing potential bias.
• **Interview Mode:** Traditionally, the GSS used in-person interviews conducted by trained interviewers. This allows for more detailed questioning and the collection of nonverbal data. However, recent GSS surveys have incorporated a web-based component to reduce costs and improve response rates. A mixed-mode approach is now common.
• **Sample Size:** The GSS typically aims for a sample size of approximately 3,000 respondents. This provides sufficient statistical power to detect meaningful differences in attitudes and behaviors.
• **Weighting:** Raw survey data is weighted to adjust for differences between the sample and the US population in terms of demographic characteristics such as age, sex, race, education, and geographic region. Weighting is essential for ensuring that the GSS accurately reflects the broader population. Understanding weighting strategies is vital for accurate analysis.
• **Data Collection Protocols:** The GSS adheres to strict data collection protocols to minimize errors and bias. Interviewers are thoroughly trained and supervised. Quality control measures are implemented throughout the data collection process.
• **Non-Response Bias:** Researchers continuously monitor and address potential non-response bias. This is a common challenge in survey research, as individuals who choose not to participate may differ systematically from those who do. Techniques like non-response weighting are employed to mitigate this bias.

Data Content and Topics

The GSS is renowned for its breadth of coverage. It includes questions on a vast array of topics, allowing researchers to explore a wide range of social phenomena. Key areas covered include:

• **Demographics:** Detailed information on respondents' age, sex, race, ethnicity, education, income, occupation, and family structure. This is foundational data for many analyses.
• **Political Attitudes:** Questions about political ideology, party identification, trust in government, and views on specific policy issues. These data are often linked to political polarization trends.
• **Social Attitudes:** Measures of attitudes towards a variety of social issues, such as gender roles, racial equality, environmental concerns, and religious beliefs. Analyzing these attitudes can reveal shifts in social values.
• **Personal Experiences:** Questions about respondents' experiences with crime, discrimination, health, education, and employment. These provide insights into individual life circumstances.
• **Social Networks:** Information about respondents' social connections and relationships, including family, friends, and coworkers. Studies of social capital frequently utilize GSS data.
• **Religious Beliefs and Practices:** Questions about religious affiliation, attendance at religious services, and the importance of religion in respondents' lives.
• **Work and Family:** Questions about employment history, job satisfaction, work-family balance, and attitudes towards parenting.
• **Happiness and Well-being:** Measures of subjective well-being, including respondents' overall satisfaction with their lives. These data are relevant to studies of positive psychology.
• **Topical Modules:** In addition to the core questions, the GSS includes topical modules that focus on specific issues in greater depth. These modules are added on a rotating basis and cover a wide range of topics, such as immigration, health care, and climate change. These modules often provide data for trend analysis.

The GSS questionnaire is continually updated to reflect changes in society and to address emerging research questions. The complete questionnaire and codebook, which provides detailed information about the variables in the dataset, are available on the GSS website.

Uses of the GSS

The GSS is used by researchers in a wide variety of disciplines. Some common applications include:

• **Tracking Social Trends:** The GSS's longitudinal design allows researchers to track changes in attitudes and behaviors over time. This is crucial for understanding long-term societal shifts. Analyzing long-term trends is a primary strength of the GSS.
• **Identifying Social Determinants of Health:** GSS data can be used to examine the relationship between social factors, such as income, education, and social support, and health outcomes.
• **Studying Political Behavior:** The GSS provides valuable data for understanding voting behavior, political participation, and public opinion. Researchers can explore the impact of demographic factors on voting patterns.
• **Examining Inequality:** The GSS can be used to study inequalities in income, wealth, education, and other areas. This can help identify social groups that are disadvantaged and inform policies to address inequality. Analyzing income inequality is a common application.
• **Testing Social Theories:** The GSS provides a rich source of data for testing and refining social theories. Researchers can use the data to examine the relationships between different social variables and to assess the validity of theoretical models.
• **Evaluating Policy Interventions:** The GSS can be used to assess the impact of policy interventions on attitudes and behaviors. Analyzing changes in attitudes following policy changes can provide valuable insights.
• **Meta-Analysis:** The GSS is frequently used in meta-analysis studies, combining its data with findings from other surveys and research to provide more robust conclusions.
• **Predictive Modeling:** Utilizing regression analysis and other statistical techniques, researchers can use GSS data to build predictive models for social phenomena.

Accessing and Analyzing GSS Data

The GSS data is publicly available to researchers. It can be downloaded from the GSS website ([1](https://gss.norc.org/)). The data is typically provided in SPSS, SAS, and Stata formats. Researchers can also access the data through the GSS’s online data analysis tool, SDA (Survey Documentation and Analysis).

Analyzing GSS data requires some statistical knowledge. Common analytical techniques used with GSS data include:

• **Descriptive Statistics:** Calculating means, medians, modes, and standard deviations to summarize the data.
• **Cross-Tabulation:** Examining the relationship between two or more categorical variables.
• **Correlation Analysis:** Measuring the strength and direction of the relationship between two or more continuous variables.
• **Regression Analysis:** Predicting the value of one variable based on the values of other variables. Multiple regression is commonly used.
• **Logistic Regression:** Predicting the probability of a binary outcome (e.g., voting or not voting).
• **Factor Analysis:** Identifying underlying patterns in the data.
• **Time Series Analysis:** Analyzing data collected over time to identify trends and patterns. Moving averages and other techniques are often employed.
• **Structural Equation Modeling (SEM):** Testing complex relationships between multiple variables.

Researchers should be aware of the GSS data’s weighting scheme and use appropriate statistical procedures to account for the complex sampling design. Resources and tutorials for analyzing GSS data are available on the GSS website and through various statistical software packages. Understanding statistical significance is crucial for interpreting results.

Limitations of the GSS

Despite its strengths, the GSS has some limitations that researchers should be aware of:

• **Cross-Sectional Design:** While the GSS is longitudinal, most of its data is cross-sectional, meaning that it is collected at a single point in time. This limits the ability to draw causal inferences. Longitudinal studies offer stronger causal evidence.
• **Self-Reported Data:** The GSS relies on self-reported data, which is subject to biases such as social desirability bias (respondents may provide answers that they believe are more socially acceptable) and recall bias (respondents may have difficulty remembering past events accurately).
• **Sample Size:** Although the GSS sample size is relatively large, it may not be large enough to detect small effects or to analyze subgroups in detail.
• **Coverage Errors:** The GSS’s sampling frame may not fully cover all segments of the US population, leading to potential coverage errors.
• **Question Wording Effects:** The way that questions are worded can influence respondents' answers. Researchers must carefully consider the potential for question wording effects. Framing effects can significantly impact responses.
• **Changing Social Norms:** Social norms and attitudes change over time, which can affect the interpretation of GSS data. What was considered acceptable or normal in the 1970s may not be today.
• **Mode Effects:** The transition to web-based data collection may introduce mode effects, as individuals who respond online may differ systematically from those who respond via in-person interviews. Analyzing response rates is important.
• **Limited Geographic Detail:** The GSS does not provide detailed geographic information, limiting the ability to analyze local variations in attitudes and behaviors.

Despite these limitations, the General Social Survey remains a vital and invaluable resource for social science research. Its long history, rigorous methodology, and broad coverage make it an essential tool for understanding societal change and the attitudes and characteristics of the American population. Researchers must carefully consider the limitations of the data when drawing conclusions and interpreting results.
