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集中できるらしい。
People who are 'nagarazoku' seem to concentrate better with a little background noise than in complete silence.
Standard kanji spelling.
Rarely used kanji form; 乍ら is an uncommon spelling of ながら.
From ながら (while doing) + 族 (tribe, group). Coined to describe people who habitually engage in activities with background media.
