I think overall demographic makeup of the country skew these numbers. If you were to look at specific cohorts than the results would be quite different. 16-20, 21-25, 26-30, 31-35 and so on, I think you'd see the numbers peak in the 21-25 mark and gradually fall from there. When you consider that baby boomers make up the largest part of our population and range from 39-58 (assuming they're born 1947-1966) I would venture out and suggest that less than 20% of them would be heavy drinkers in this survey. So if this 36% number is to apply to the entire population than I think it's probably pretty accurate, but if you were to look at the under 30 crowd than it's likely above 50%.
