There are many sources for data on before and after school cell phone bans. Oregon is far from the first to implement this. 35 US states have some form of school cell phone ban, and I believe the UK is doing a nation-wide ban. There is a good amount of supporting data measuring results on this topic.

Any data that discusses the effects of jurisdictions that still have refused to pass or enact such provisions?
