What factors determine whether data are identifiable vs non-identifiable in reporting or analysis?

• A. Whether data include direct identifiers or can be linked to individuals; plan to publish with de-identified data; minimize risk
• B. The funding source
• C. The language used in survey
• D. The number of participants

Answer: (A)

The key idea here is how identifying information is handled and what is planned for sharing the data. Data are identifiable if they contain direct identifiers (like names, addresses, social security numbers) or if they could practically be linked to a specific person. If you plan to publish or share the data in a de-identified form and implement steps to minimize risk (removing or masking identifiers, limiting variables, etc.), the data become non-identifiable or have much lower re-identification risk. This focus on direct identifiers, the potential to link data to individuals, and the commitment to de-identification when reporting or analyzing is what determines identifiability. The other factors listed don’t determine identifiability. Funding source doesn’t change whether data can identify someone, the language used in a survey doesn’t affect identifiability, and the number of participants doesn’t by itself decide identifiability (though small counts can affect risk in some contexts, it’s not the primary determinant).
