Assuming insurers to be among the least biased collectors of 
data, try this page:

https://www.iihs.org/topics/fatality-statistics/detail/bicyclists

Most recent year shows 62% of fatalities no helmet, 15% with 
helmet, remainder unknown.

Also notable, as discussed here occasionally for a couple of 
decades, 21% of fatalities were legally drunk. (No numbers 
for drugs or mental deficiency)
