According to the 1% model, 80,000,000+ million people stutter across the globe. Do you really beleive that as a stutterer? There are so many countries and nations that do not have a population of 80,000,000. California has a population of 39 million The UK has a population of 63million Germany has a population of 83 million There are apparently as many stutterers as these nations/states and we could make up the entire nation of Germany? Apparently this is also just refering to childhood onset stuttering into adulthood. Can we please acknowledge something is wrong or skewed in the literature? They are obviously not asking the right questions, Id love to see these surveys. Are the vast majority of stutterers hiding somewhere together? I just cant beleive this number and something is not right. Unless these people absolutely refuse to speak.
