If we placed a pole for six and under state - you would need to survey 200 parents who have kids from each age division to get a representative sample. Not just the parents of kids who are currently 6 and under. Each voting member could only vote in one age division if they have more than 2 kids. How do you develop the mailing list for the random sample? You would have to do it three years in a row to get a rolling average. It would be similar to forcasting school enrollments.
