It's one state in one country but this was a nice little blurb to read:

It's basically a bill to extend current requirements that textbooks be available to students in a format the blind and visually impaired can use from just public elementary and secondary school to universities etc.

But what stood out to me was this line (emphasis mine):

That's an interesting statistic. I would like to see where it comes from, but it's certainly something to keep in mind as web developers who are wondering if the 3% number that's been floating around is true... if you're developing for a country that has veterans in combat, you may have higher rates of disabled visiting your site or using your app than what other statistics mention.
