I think you're right, because in the old network posts there's one missing person from way back in the first days, and they were the youngest. 18 years old, with a subject number of 6183AUN5. No other numbers in the 6000 range, and no other teenagers, thank fucking God.
And yeah, we need more demographic data, if people are willing to answer the questions. People might just be a little gunshy of filling in surveys for awhile.
