Which of the following data types would be classified as personally identifiable information (PII)?

PII refers to data that can identify a person, either on its own or when combined with other information. A Social Security Number is a direct, unique identifier tied to an individual, so it is PII because it can identify that person by itself. Hair color, city of birth, and height describe a person but do not uniquely identify them alone; they’re demographic attributes. They’re not direct identifiers like an SSN, though in some contexts they could help narrow down who someone is when mixed with other data.
