What type of information is classified as PII?

The classification of information as Personally Identifiable Information (PII) is focused on data that can be used to uniquely identify an individual. This includes names, addresses, phone numbers, Social Security numbers, and other information that can directly point to a specific person. The correct choice highlights the fundamental aspect of PII: its ability to single out an individual, making it crucial for privacy and security considerations in various contexts, especially in legal and regulatory frameworks.

In contrast, general demographic data can include broader categories such as age ranges, gender, or income brackets, which may not uniquely identify an individual. Data shared on social media may contain PII but isn't solely classified as such unless it meets the criteria of identifying an individual directly. Aggregate user statistics encompass groups of people and trends, lacking the individual specificity required to be classified as PII. Thus, recognizing that PII must specifically identify an individual is key to understanding its significance in privacy laws and practices.
