Gender

In the vast majority of countries, the population of amateur radio operators is predominantly male. In China, 12% of amateur radio operators are women,^[29] while approximately 15% of amateur radio operators in the United States are women.^[30] The Young Ladies Radio League is an international organization of female amateur radio operators.^{[citation needed]}

A male amateur radio operator can be referred to as an OM, an abbreviation used in Morse code telegraphy for "old man", regardless of the operator's age. A single female amateur radio operator can be referred to as a YL, from the abbreviation used for "young lady", regardless of the operator's age. A licensed married female is sometimes referred to as an XYL.

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]} the average age of amateur radio operators is relatively high. In some countries, the average age is 68 years old.^{[citation needed]}

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.^{[citation needed]} The average age of most amateur radio operators is approaching 70 in most European countries.^{[citation needed]}

Some national radio societies have responded to the aging ham population by developing programs specifically to encourage youth participation in amateur radio, such as the American Radio Relay League's Amateur Radio Education and Technology Program.^[31] The World Wide Young Contesters organization promotes youth involvement, particularly among Europeans, in competitive radio contesting. A strong tie also exists between the amateur radio community and the Scouting movement to introduce radio technology to youth. WOSM's annual Jamboree On The Air is Scouting's largest activity, with a half million Scouts and Guides speaking with each other using amateur radio each October.^[32]
