So after hitting a plateau, it looks like home adoption rates are bumping up again. According to Pew Research Center’s Internet & American Life Project, 63% of adult Americans now have broadband internet connections at home, a 15% increases from a year earlier.

The even happier news is that it’s the traditionally offline crowd that’s getting on the broadband bandwagon:

Broadband usage among adults ages 65 or older grew from 19% in May, 2008 to 30% in April, 2009.

Overall, respondents reporting that they live in homes with annual household incomes below $30,000 experienced a 34% growth in home broadband adoption from 2008 to 2009.

On a less positive note, African Americans experienced their second consecutive year of broadband adoption growth that was below average.

Broadband users think it’s really important; 55% of broadband users view a high-speed link at home as “very important”. Still, 7% of Americans are dial-up internet users at home. (That’s about half of the percentage of last year.) They had a range of reasons they didn’t go online at home: it was too expensive. Just not interested, can’t get access, and more.
