WASHINGTON, D.C. -- Americans' self-reported Internet use has risen from 69% in 2002 to 87% today, but significant gaps in usage remain across age, education, and income groups. Over a third of seniors still do not use the Internet.
Americans aged 65 and older saw the biggest change in Internet use among any age category over the last 11 years (up 32 percentage points), but even with those gains, a third of older Americans say they don't personally use the Internet. In contrast, 30- to 49-year-olds report almost universal use of the Internet today, with slightly lower but still high levels of use among adults younger than 30 and 50 to 64.
Those making less than $20,000 a year have experienced growth almost as large as that among seniors, but again, a considerable percentage of low-income Americans still do not use the Internet. On the other hand, use of the Internet is essentially universal among those making $50,000 a year or more.
Finally, adults with no more than a high school education have increased their use of the Internet significantly over the past 11 years, but, at 77%, their rate of use remains the lowest of any educational category. More than nine in 10 Americans with at least some college education use the Internet, including nearly universal use among those who have postgraduate education.
Implications
Clearly the Internet has taken its place as a fixture in Americans' daily lives. Almost nine in 10 Americans (87%) say they personally use the Internet, a jump from 69% 11 years ago. Still, certain pockets of Americans remain disconnected from this increasingly central portal for news, business, and communication, including in particular older Americans and those with low levels of education and income.
Survey Methods
Results for this Gallup poll are based on telephone interviews conducted Oct. 3-6, 2013, on the, with a random sample of 1,028 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia.
For results based on the total sample of national adults, one can say with 95% confidence that the margin of sampling error is ±4 percentage points.
Interviews are conducted with respondents on landline telephones and cellular phones, with interviews conducted in Spanish for respondents who are primarily Spanish-speaking. Each sample of national adults includes a minimum quota of 50% cellphone respondents and 50% landline respondents, with additional minimum quotas by region. Landline and cell telephone numbers are selected using random-digit-dial methods. Landline respondents are chosen at random within each household on the basis of which member had the most recent birthday.
Samples are weighted to correct for unequal selection probability, nonresponse, and double coverage of landline and cell users in the two sampling frames. They are also weighted to match the national demographics of gender, age, race, Hispanic ethnicity, education, region, population density, and phone status (cellphone only/landline only/both, and cellphone mostly). Demographic weighting targets are based on the March 2012 Current Population Survey figures for the aged 18 and older U.S. population. Phone status targets are based on the July-December 2011 National Health Interview Survey. Population density targets are based on the 2010 census. All reported margins of sampling error include the computed design effects for weighting.
In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
