Textbooks offer instructors an opportunity to promote data visualization and statistical literacy throughout the sociology curriculum. In this study, we examined 463 data visualizations from 27 textbooks for Introduction to Sociology, Social Problems, and intermediate elective courses to illuminate the range of data visualizations and their use of statistical data and numerical variables. We find that textbooks rely on a narrow range of data visualizations (e.g., bar/column charts and tables), statistical data (e.g., percentages), and numerical variables (e.g., age). Introduction to Sociology textbooks used more data visualizations, and Social Problems textbooks incorporated more types of statistics. In contrast, intermediate-level textbooks presented more measures of central tendency. Overall, our results suggest textbooks could better integrate a broader range of figures, statistical data, and numerical variables. We conclude with resources for integrating data visualization in instruction.
