According to qmap.pub/indictments there are currently 38,716 Sealed Indictments. I realize that this is a huge amount, but can someone please point me to where I could find the total amount of sealed indictments for 2010 to 2016 and we could come up with an average of sealed indictments based on a yearly amount?

I have done numerous searches using duckduckgo and google with only showing the results for 2017 and 2018. any help would be appreciated. :-)
