Which of the following is considered personal information?

The selection of marital status as personal information highlights its relevance in the context of the Data Privacy Act, which defines personal information as any data that relates to an identified or identifiable individual. Marital status is considered personal information because it relates directly to an individual and can reveal personal circumstances about their life. This type of information is sensitive and potentially used to make inferences about other aspects of a person's life, such as their family dynamics, social standing, and even financial responsibilities.

In contrast, a corporate registration number, while it does pertain to legal entities, does not identify or provide information regarding an individual personally. Similarly, a personal identification number (PIN) can be security-related but typically functions as an access key rather than information defining personal traits or circumstances. The passport number, while it uniquely identifies an individual, is primarily a record associated with travel documentation rather than a standalone identifier of personal attributes. Therefore, marital status stands out as a direct reflection of individual personal status in relation to privacy laws and practices.
