The data used for these visualizations came from the Substance Abuse and Mental Health Services Administration Center for Behavioral Health Statistics and Quality, and was taken from their 2016 National Survey on Drug Use and Health. These data visualizations compare marijuana, cocaine, and methamphetamine usage, in the past 12 months, by Americans aged 18-25, as shown by percentage of the population, through a self-reported survey. The charts go on to show the way different socioeconomic variables impact this usage, including gender, race, education level, and employment type.
The “gender” section compares use between males and females; the “race” section compares use between American Indians, Asians, Blacks/African Americans, Hispanic/Latinos, Two or More Races, and Whites; the “education level” section compares usage between people without high school diplomas, high school graduates, people with some college experience, and college graduates; and finally the “employment type” section compares people who are unemployed, work part-time, work full-time, and others (defined as those who do not fit into the other categories for reasons such as housewifery, disability, etc.)
A lot can be learned and extrapolated from these charts, including how the price, intensity, and stigma around certain drugs may impact who takes what.
