noun
people who do something while listening to the radio or watching TV
Refers to people who habitually study, work, or do other tasks with the radio or television on in the background. The term comes from the ながら (while doing) pattern.
彼はいつも音楽を聴きながら勉強する、いわゆるながら族だ。
He always studies while listening to music; he's what you'd call a 'nagarazoku'.
ながら族の人は、静かな環境よりも少し音があったほうが
People who are 'nagarazoku' seem to concentrate better with a little background noise than in complete silence.
ながら is the grammatical particle meaning 'while doing', which is the basis for this term. ながら族 is a noun referring to people who do things while something else is on.
From ながら (while doing) + 族 (tribe, group). Coined to describe people who habitually engage in activities with background media.
