EXPLORING THE DIGITAL NATION:HOME BROADBAND INTERNETADOPTION IN THE UNITED STATES EXPLORING THE DIGITAL NATION:Home Broadband Internet Adoptionin the United States NATIONAL TELECOMMUNICATIONS AND INFORMATION ADMINISTRATIONin theU.S. DEPARTMENT OF COMMERCE EXPLORING THE DIGITAL NATION:Home Broadband Internet Adoptionin the United States FOREWORD The Internet Age is here. The effective use of this technology and all that it can provide is a key tosuccess for businesses and individuals. Knowing this, the Obama Administration seeks to ensure thatall Americans have affordable access to broadband Internet services.Accomplishing that goal,however, requires a set of facts about Internet use that can underpin and guide this policy objective. InExploring the Digital Nation: Home Broadband Internet Adoption in the United States, the CommerceDepartment fulfills its promise to provide authoritative, nationally-comprehensive data on access tothe Internet throughout the United States. This new study follows the February 2010 NTIA researchpreview,Digital Nation: 21st Century America’s Progress Toward Universal Broadband Internet Access.Both studies draw on the Census Bureau’s Current Population Survey Internet Use Supplement, asurvey of approximately 54,000 households conducted over one week in October 2009. The Censusdata show increases in adoption of broadband services at home over time for virtually all demographicgroups.The data also reveal that demographic disparities among groups have tended to persist.Persons with high incomes, those who are younger, Asians and Whites, the more highly-educated,married couples, and the employed tend to have higher rates of broadband use at home. Conversely,persons with low incomes, seniors, minorities, the less-educated, non-family households, and the non-employed tend to lag behind other groups in home broadband use. The new study takes the analysisto another level. This report presents the most accurate statistical profile of U.S. broadband Internet adoptioncurrently available. The report features new analysis of “adoption gaps,” i.e., the differences in averagebroadband Internet adoption at home among different groups after controlling for demographic andgeographic factors. There are certain groups in the population that have lower adoption rates evenafter taking account of differences that typically affect broadband usage.For example, the homebroadband adoption gap between the lowest-income households and higher income brackets rangesfrom 16 to 34 percentage points, even after controlling for differences in education, age, race,ethnicity, household size, urban-rural location, foreign-born status, disability status and state ofresidence.The gaps between Whites and Blacks registered at 10 percentage points and between Whites and Hispanics at 14 percentage points, even after controlling for household characteristics. Asimilar analysis found the urban-rural gap to be 7 percentage points.A special section presents ourfindings on users with disabilities, who tend to be older and part of lower-income groups. We look forward to continuing our study of this important subject in the future. Most of all, we hopethat the data we make available to the public will be of use to the research community and policy-makers around the United States in their quest to understand the nature of Internet access. Throughtheir research and ours, we hope to learn how to continue to make the benefits of this extraordinarynew platform available more widely throughout the country. Rebecca M.
