The Internet is rapidly becoming an essential source of information about health, nutrition, finances, and current events. Neunschwander, Abbott, and Mobley (2012) were interested in inequality of access to the Internet as a function of the characteristics of the participant. They recruited a very large sample of participants from the Indiana Supplemental Nutrition Assistance Program and surveyed them about their access to the technology. They observed that racial minorities, older persons, and persons with lower educational attainment were less likely to have a functioning computer at home and, relatedly, were less likely to have access to the Internet. Below are frequencies similar to those observed by the researchers.
