Huh, that's much less than I expected! Apparently it's just for adult population (correctly). Apparently that varies from year to year (in 2024 it was 64%), and by race (highest in white people 70%). I also wonder how that looks when we exclude older people (let's say over 60) who more often have health problems or just tolerate alcohol very badly).

It's higher in my country so good to know that USA drinks less than I assumed.
