Ofcom Released Age of Radio Amateurs Data
/Following a Freedom of Information request about the age of radio amateurs, Ofcom said they do not hold Date-of-Birth information for many radio amateurs but released what information they do have.
Ofcom say "We do not hold a full breakdown of the age of issued amateur radio licensees as date of birth is not a mandatory field for licence applications."
In September 2000 the then communications regulator (RA) abolished the ban on people under 14-years-old holding a Full amateur licence, since that time a person's date of birth has served little regulatory purpose.
The data Ofcom released showed they only had Date-of-Birth information for:
7,312 out of 28,845 Foundation licences
4,104 out of 12,127 Intermediate licences
44,944 out of 54,072 Full licences
As of 1st March 2021 there was a total of 95,044 valid UK amateur radio licences.
