yes under 16's are included in the attendances, everyone who goes through the attendances is supposed to be counted.
from a health and safety point of view you can imagine how important that is.
i suppose this only possible with a half empty ground, it would be hard to get away with in a big championship match.
anyone remember the mayo v dublin match a few years ago where it was oblivious to anyone on the hill that there was a bigger crowd than normal in there, everyone was waiting for the attendance to be announced in the second half but it never was.
all the papers just reported it as a full house.
