At what age do you legally become an adult?

The age that you become an adult ranges anywhere between 14-21 around the world. The most common age is 18. The age of majority is also 18 in the United States, however, one must legally be 21 to drink alcohol. Some states also have slightly higher ages of majority, ranging from 19-21. Currently, Mississippi is the only state that recognizes age 21 as the age of majority, but some states (such as Texas) have an age of majority of 18 but recognize anyone under 21 as a "minor".
