Back in the dark ages and by virtue of my 'position' at the time, I was commissioned to run a couple of scientifically conducted telephone polls. The demographic questions are mostly to use to evaluate whether a truly random cross section of the population was reached. If mostly senior citizens or mostly twenty somethings etc. are polled, the results cannot be considered to be a good cross sample.
They also use this information to produce other statistical analysis, i.e. among senior citizen X number supported whatever and X number opposed; among Republicans......among parents.....among singles....etc. etc. etc.
I am guessing that some in all age groups and categories will be influenced by emotional response to things though.
