What is the minimum age to vote in Guam?

The minimum age to vote in Guam is 18 years old. This aligns with the legal voting age established in the United States and many territories, where individuals must be at least 18 on or before election day to participate in elections. This standard ensures that voters are deemed mature enough to make informed decisions regarding their governance and civic duties. The age requirement is designed to promote responsible voting, reflecting a balance between youth engagement in democracy and the maturity often expected at adulthood. Hence, 18 years old is the correct answer, as it is consistent with both local and federal voting regulations.
