What aspect of personal data makes it identifiable?

The aspect of personal data that makes it identifiable is its connection to an individual's characteristics. This is because personal data typically includes information that can directly or indirectly relate to an identified or identifiable individual, such as names, identification numbers, location data, and online identifiers.

When personal data is linked to specific characteristics of a person, such as their demographics, behavior, or preferences, it enhances the ability to identify that individual within a larger dataset. This connection allows for the data to be utilized in ways that are specific to that individual, making it crucial for privacy considerations and the ethical handling of such information.

For example, if a dataset includes age, gender, and interests tied to a specific individual, it becomes much easier to identify and analyze that person's behavior compared to data that presents only generalized information about a population or abstract classifications without any clear linkage to personal identities.
