Pew Internet & American Life Project has released their most recent statistics on broadband adoption among adult Americans:

Home broadband adoption stood at 63% of adult Americans as of April 2009, up from 55% in May, 2008.

The most interesting bit of data in the report is that the following groups achieved above average increases in adoption: senior citizens; low-income; high-school graduates (no college); older baby boomers, and; rural Americans.
