This is one resource:  
https://www.searchlogistics.com/lear...ry-statistics/
And I use AI to search for other stats. In Ohio, we have 9+Million adults. 
Estimated that 1% OF adult US population plays lottery daily, and 10% weekly. 
One percent of 9M is about 90,000 Ohio Lottery players. 
I need 1,000 of those for my Newsletter to be worthwhile.
