A recent poll conducted by Roper Starch Worldwide, Newport Beach, CA, reveals 12% of the adult population in the United States access the Internet. That's about 20 million people. The study was conducted via in-person interviews with a nationally representative sample of 1,999 Americans 18 years of age and older. The margin of error is about 3%, due to sampling.
The poll also showed that Internet use is higher among Americans with total household incomes of $50,000 or more (nearly three-in-ten), compared to nearly one-in-ten among those with total household income of $30,000 to $50,000.
Intelliquest, Austin, Texas, and Nielsen, New York, also released Web user surveys this month.
