The Japanese government's September 2004 white paper on the labor economy defines NEETs as 15-34 year olds who have completed school, do not work, are unmarried, are not homemakers and are not furthering their educations.
根據日本政府於 2004 年 9 月所公布的《勞動經濟白皮書》，將這群已完成學業，但無業、未婚、不負責家務也不參加進修的 15 到 34 歲族群，定義為「尼特族」。
