Quality of the estimations is extremely shitty. I've heard everything from 1% to 5%. And for persistence into adulthood, anything from 40% to 15%. This is mostly because diagnostic criteria are extremely up for interpretation, and it usually comes down to the doctor if you get a diagnosis or not. I read one particular study that attempted to correlate location with ADHD incidence, and then it turned out that it came down to how the local specialists felt about it. Reminds me of the reason the DSM comittee rejected cPTSD from inclusion into their officially-opinionated manual. "If we add this, too many people would be affected, we simply can't pathologize this many people at once".
