Although I cannot speak for other countries, here in the UK ours is a hobby mainly of older people and mainly men. When I was fitter, I gave several talks to local radio clubs in East Anglia and without exception it was mainly OAPs who came along. OK there were a few youngsters and women, but the vast majority were older men.
Amateurs and SWLs are a dying breed, unless we can attract young people into the hobby. I am 67 and will be dead within 30 years, probably a lot sooner. An aging population will not buy so many rigs, will not support magazines etc. Numbers will fall, activity will fall, interest will drain away.
In 20-30 years we will be very much in uncharted territory. What will our hobby be like in years to come?
