The only real significant trend in that report is a huge decline in child fatalities, and that's probably because so many fewer children ride bicycles than they used to. Kids don't ride bikes to school anymore, they're ferried in land barges. Heck, a few years back a friend who lives within 1.5 miles of a school made her son walk to school one day when he clearly intentionally delayed to force himself to miss the bus (thinking she would drive him) - she was told that she'd be reported to CPS if her son walked to school again. This is in an area where all the crossings have lights and there are sidewalks all the way.
Schools around here usually don't even install bike racks anymore - they feel that it's inviting students to ride and if they get hurt the school could be sued.
