Taint necessarily so
Irv:
I hear the "hobby participation is way down" urban myth a lot, and it mostly comes from the decrease in the circulation of the hobby magazines.
Recently, I spoke with a modeler who has recently retired from the NMRA board, and I asked him what the NMRA sees as participation in the hobby - and he said the NMRA regularly sees surveys done by the various major hobby vendors. Hobby participation is flat or slightly increasing - but it's definitely not shrinking, according to these surveys.
He said age also matters. Most members of the hobby are male, and typically guys are introduced to the hobby from 8-12, and they do what the can with limited resources until they reach 20, at which time they drop out of the hobby to focus on schooling, spinning up a career, and starting a family.
Most return to the hobby in their 30s or 40s, once the kids are older and the career is established. They then continue in the hobby through retirement, building one or more layouts and spending much more on the hobby.
This age profile plays into what we're seeing right now. Baby boomers were born from 1945 - 1965, and are in their early 40s to early 60s and back in the hobby - and they started returning to the hobby mostly in the 70s and 80s, trickling off into the 90s. So this age group will have been creating hobby growth in the last 20-30 years.
Next comes Gen X, a far smaller generation than the Baby boomers, and they're currently in their early 20s to early 40s. If you couple the tiny size of Gen X with the fact they're currently in the time when most people drop out of the hobby, then this group will have been dropping out of the hobby in the last 20 years, but will be reentering the hobby in the next 20 years. Since Gen X is so small, their exit from the hobby will have caused the numbers to drop slightly over the last 20 years, and they will be causing the hobby ranks to grow slowly over the next 20 years.
Finally, there's Gen Y, currently aged zero to their early 20s. Gen Y is way larger than the Boomers, and studies show their parents and grand parents lavish them with stuff - so Gen Y is used to conspicuous consumption. In the teen years, most modelers don't buy a lot of stuff - but Gen Y's parents/grandparents do buy lots of stuff for their kids/grandkids. We should see an uptick model trains for this group - and that's exactly what we're seeing. If you check out news services like Reuters, you will see they've been reporting an increase in model train sales in the holiday season since 2005.
Gen Y, however, will be leaving the hobby also as they move into their 20s over the next 20 years - so they will add very little to the hobby until 20 years from now when this massive generation that's larger than the boomers returns to the hobby.
So putting this all together, what should we be seeing?
Boomers coming back into the hobby (big generation, more modelers entering the hobby since 1970s) + Gen X (tiny generation, more modelers leaving the hobby since the 90s, will be staring to come back in next 20 years) + Gen Y (huge generation, parents are lavishing them with goodies, but they will be leaving the hobby over next 20 years) so we have:
Moderate hobby growth in the 70s and 80s, tapering off in the 90s, going flat in the first decade of the 2000s, slowly starting to increase from 2005 and into the 2010s, and then taking off with record hobby growth again in the mid 2020s and beyond as the massive Gen Y returns to the hobby.
