IIRC US bandwidth is increasing roughly 10% per year. I'm pretty sure it's some private company that does these metrics though, as I think this is the only thing the government releases:
I forget the exact numbers off the top of my head, but I just remember it being really difficult to actually find the statistic. But the takeaway is that although we are theoretically #27 in terms of broadband speed, our actual broadband speeds aren't that much lower than in other countries.
The Akamai report here is probably the most credible source. I remember there being one other report that covered this info, but I can't find it right now.
