Here are extracts from a discussion between David Boulton and Andrew Johnson and my comments. LINK
At minute 34.30 - dyslexia is an inability to learn to read which is of Unknown Origin. It impacts usually depending on the researcher three to five percent of the population. Unfortunately, it's become such a big thing politically and profitably that they push that three to five percent which I kind of agree with to almost 15 to 20 percent because there's a whole lot more opportunity to intervene.
I have said the same thing for the past over a decade.

There are many other posts I wrote over the years.
I believe the % of kids who may fall into the dyslexic category are no more than 2%. Even if we accept the 3 to 5 % as mentioned by David above that leaves a lot more who are unable to read due to ‘Dysteachia’.
