> >Thanks for sharing this interesting information. Can you tell me if you are tracking just U.S. type hazmat headlines or global (as best you can)?
The headlines are global in reach, as provided by Google's English language service. So events large enough to make the English press covering, China, Europe, India etc. appear in the summary. The breakdown between US and foreign events has been very consistently 75% and 25% others through the years.
Further caveats and interpretations of the data can be found in a JCHAS article published earlier this year at

Let me know if you have any questions about this.
