Figure 5.18: Figure 5.16 Comparison of Demographic Characteristics of Survey Sample to U.S. Population This bar chart compares the percentages of respondents in Laumann’s survey of sexual behaviors who meet selected demographic characteristics to the percentages with which the same characteristics are found in the U.S. population. The matches are very close, supporting the ability to generalize from the survey results to the larger U.S. population (Michael, Gagnon, Laumann, & Kolata, 1994).
