Idol birth-year cohorts — reading “00-liners” and generation talk carefully아이돌 출생연도 코호트 — ‘00라인’·세대 이야기를 신중히

“00-liner” style labels group idols by birth year (often 2000). They are fandom shorthand — not agency ranks — and they are easy to mix with “4th/5th generation” marketing language.

• Cohort = birth year cluster (e.g., born in 2000).
• Generation = debut-era marketing buckets (see our generations cheat sheet).
• Verify with full birth dates on the ages hub; year-only lists can mis-rank people born in December vs January.
• Etiquette: cohort memes are fine; using them to dunk on “too old / too young” is not useful facts.
