Upwards of 65% of all licensee's are only a Technician Class license holder.
Where did you get your figures or did you just make up a random number out of thin air?
As of November 13, 2012, there were 348,786 Technicians and a total of 716,672 total licensed amateurs which is about 48%. My source is: http://www.ah0a.org/FCC/Licenses.html
What is your source?
About 50,000 licenses are club call signs and contest clubs, which at one time was allowed to hold more then one call sign per a club.
The number of current, unexpired licenses held by individuals
is now about 717,000. That does NOT include clubs and other secondary licenses. 717,000 individuals.
Figure out how many General, Advanced and Amateur Extra class license holders are dead, but no one turned in their death certificate.
Subtract those numbers from the 715,000 licenses and then divide by 100 - since 715 minus 50,000 minus probably 75,000 = 125,000
716,672 - 125,000 = 591,672
The license totals always include a certain percentage of dead and disinterested folks who are inactive and will never renew. Why do you assume all Techs are active?
It stands to reason that there are more people that holds a technician class license, and most of them are new hams or licensed less then 20 years, so more of them are probably still alive.
No, it doesn't.
The Technician license has been around since 1951. 20 years ago was 1993. A lot of folks getting ham licenses today are older, too.
It stands to reason that a higher % of General and Advanced and Amateur Extra licensee's would be beyond retirement age and closer to their death bed then not.
Not at all. Lots of young folks get their licenses and upgrade fast.
In college they call this stuff Statistic's.
348,786 Technician class license holders, if you have 325,000 living Technician class license holders and only 291,672 of all of the others, you have more then 50% that are technician class license holders.
Your numbers are based on invalid assumptions.
