Age

Most countries do not have a minimum age requirement in order to earn an amateur radio license and become an amateur radio operator. Although the number of amateur radio operators in many countries increases from year to year,{{Citation needed, date=September 2007 the average age of amateur radio operators is relatively high. In some countries, the average age is over 80 years old,{{Citation needed, date=April 2016 with most amateur radio operators earning their license in their 40s or 50s.{{Citation needed, date=September 2007 The unfavourable age distribution has led to a slow decrease in amateur operator numbers in most industrialised countries due to attrition, but in countries which do not apply yearly licence fees, the effects are not immediately noticed. It has been estimated from German statistics, which are considered the most reliable, that the net decrease currently is in the order of 1 to 1.5% per year.
