At what age is a person considered an adult?

A person is legally considered an adult at 18 years of age in the state of Illinois, which aligns with the majority of legal standards across the United States. At this age, individuals gain the legal rights to enter into contracts, vote, and engage in various activities that are restricted to minors.

Choosing 21 years of age might stem from confusion regarding specific legal drinking age regulations or other age-related laws, which set 21 as the minimum age for alcohol consumption. However, this is not the age at which one is deemed a legal adult for all other purposes.

The age of 25 is relevant in certain contexts, particularly regarding car insurance rates or specific requirements like full access to certain medical records, but it does not pertain to general adulthood status.

Similarly, 16 years of age often represents the minimum age for obtaining a driver's license or for some other rights, but it does not establish adult status in legal terms in Illinois. Thus, adulthood is definitively recognized at 18 years of age.
