Here's the citation, from the Official YouTube Blog:

"We will continue the significant growth of our teams into next year, with the goal of bringing the total number of people across Google working to address content that might violate our policies to over 10,000 in 2018."

I expect that the data is the same as what is found on the YouTube Artists site, which has music data for different geographic regions.

Go to https://artists.youtube.com/insights/location and click on "How is this calculated?".
