First off, thanks for all of your hard work. This looks like it will be of considerable importance for researchers and policymakers alike!
I was wondering if you could help me understand the significant decrease in the number of events reported in 2015-16? For example, the 2014 file captures 6,830,808 events, but the 2015 file only contains 2,394,415. What might explain this decrease?
Also, I understand that you all use the CAMEO coding scheme, but is there a TERRIER specific codebook?
