Why Puerto Rico is 18 (not 21 like mainland)

• US Commonwealth status: Puerto Rico is a US territory, not a state. Federal laws apply selectively.
• National Minimum Drinking Age Act 1984: required states to raise drinking age to 21 or lose 10% of federal highway funding. Applies to “states” not territories.

• Cultural history: Spanish-Caribbean culture, alcohol integrated into family + social life from young age.
• Tourist economy: 18+ rule supports massive Caribbean cruise + beach tourism market.
• Political status: ongoing debate about statehood vs commonwealth vs independence. Would change drinking age if becomes a state.

• Wyoming + Louisiana last: held out longest before 1988.
