unduplicated
Not copied once
Unduplicated means not copied or repeated—appearing only once in a count or set.
The term is common in administrative and research contexts where avoiding double-counting matters: unduplicated enrollment figures, an unduplicated list of participants.
Each item or person is counted exactly once, regardless of how many times they appear in the raw data.
