As of May 2010, two thirds (66%) of American adults have a high-speed broadband connection at home. This is unchanged from our April 2009 finding that 63% of American adults had a home broadband connection. The remaining 34% of the adult population outside of home broadband users includes those who go online using a dial-up connection (5% of adults), those who do not go online from home (26%) and those who go online from home but are unsure what type of connection they have (3%).
This three percentage point difference between our April 2009 and May 2010 surveys (a difference that is not statistically significant) translates into an overall year-to-year change in home broadband adoption of just 5%, the lowest year-to-year change in recent years.
