Pew Internet and American Life Project reports that more than 22 mln American adults (age 18 and older) have iPods or MP3 players. And, though the study did not include teens, the review suggests that there are likely several mln more MP3 players owned in the teen world. 14% of men have the players, compared to 9% of women. 19% of those under age 30 have iPods/MP3 players. 14% of those ages 30-39 have them. 14% of younger Baby Boomers (ages 40-48) own them. 24% of those who live in households earning more than $75,000 have them.
