Do you know what your megabit-per-second download speed is?

A Commerce Department survey provides some initial evidence that yes, a digital divide exists – thanks in part to murky business practices.

The information, compiled in a national broadband map, shows which populations have access to high-speed internet.

In DC, only 12 percent of homes can get broadband speeds as high as 25 megabits per second – compared to 98 percent of homes in Montgomery County and 99 percent of homes in Fairfax and Arlington Counties.

The survey doesn’t include pricing or real (vs company advertised) speed information. Still, it provides new information that documents the digital divide, notes The Washington Post in an article today.
