it woul be better for you to confirm first if there are 60% younger than 30 who are interviewed.
Without it, we are engaging in speculations. all the more reason why Pulse Asia's survey is mere speculations. if they showed the breakdown of what the pool was comprised of, specifically age-brackets then I would think of it not any better than istorya's poll.
given that both of us don't know the breakdown of the 1,200 surveyed as far as age is concerned and knowing that AGE is a very important aspect in this particular survey, then why believe in this survey in the first place?
knowing that there's something missing, an important one at that, you'd still fall for it hook, line and sinker.
