This is a more generalized question for the US as a whole and I realize that specifics may vary from state to state.
Is an emancipated minor considered to be a legal adult? Is an individual ever considered an adult at any age other than 18, both in being older or younger? Does charging a minor with a crime as an adult make them legally an adult in any other way?

Laws vary from state to state, but in MD a person legally becomes an adult at 18. An emancipated minor is just that--a minor, but as emancipated they are no longer under the control or support of their parents. A minor can be charged with certain crimes as an adult but that has nothing to do with establishing their adulthood for other things, such as voting, drinking (age 21), etc.
