However, 47.1 percent of respondents were younger than 65....
Which mean only 22.1% are under 55. And, it does not give ANY clue as to the age distribution of the remainder.
Without further information, "which I think is a good sign," has no rational basis in fact. Great wishful thinking...and I hope you are correct.
What remains unknown is the response rate stated as it reflects actual age distribution of attendants of the show. 74, 73 and 83 responses were from 18-34, 35-44 and 45-55 respective of the total 936 responses.
