Comparison of Hasbro player age estimate against surveys of new generation and OSR gamers

Comparing the age profiles from many surveys scraped from the web throws out a couple of different profiles:
- the contemporary forum user
- the old school gamer
- Hasbros estimate of the general populace

Two high-detail surveys return a year by year curve we can use to classify populations:
- a twitter demographics survey 2020
- the OSR survey by Questing Beast et al in 2016

Comparing these to the WotC 2000 and Hasbro 2020 estimates of player populations shows that the publishers are counting a population of younger gamers who are not appearing in forum responses.

This gives relatively distinct player profiles:
- OSR survey, show a population with half younger than 31, 80% younger than 42.
- the new generation player population appears to be half younger than 24-25 and 80% younger than 29-34.
- Hasbro estimates 50% of players younger than 27 and 80% younger than 36; closer to the new generation.

The split between the Hasbro curve and the general population response is an indicator that the players of D&D and those talking about it online are not perfectly overlapping.
- it suggests there are players too young to participate in online discussions (~12% under 12 years old)
- the Hasbro numbers also suggest there is a larger tail of older gamers undercounted in online discourse: survey responses would suggest only ~23% of players are over 31 years old but Hasbro estimates they are closer to 40% of the population.
