An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service. Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation. As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication. About three million amateur radio operators are currently active worldwide. Amateur radio operators are also known as radio amateurs or hams. The term "ham" as a nickname for amateur radio operators originated in a pejorative usage (like "ham actor") by operators in commercial and professional radio communities, and dates to wired telegraphy. The word was subsequently adopted by amateur radio operators.

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. Average age is approaching 70 in most European countries.
