Thanks for sharing. The Ars Technica article focuses on differences between states but I think there is very little to be learned from that chart. For instance, New Jersey is the state with the biggest reduction, but that number represents a reduction from 217 to 190. Does that mean anything? In the previous 3 years, New Jersey had 175, 179 and 217 deaths. The trend is useful for the country as a whole, but the numbers for the individual states are small enough for the per-year variations to represent noise or one-offs (like a major events with drinking, or a nasty accident).
