PUERTO RICO QUICK FACTS:
-- Puerto Rico has been under U.S. jurisdiction since 1898, its people citizens since 1917. Residents of the island cannot vote in the general presidential election in November because the island is a territory.
-- Puerto Rico has a representative in the House, called a Resident Commissioner, who has limited voting power. The island has no representation in the Senate.
-- The official languages are Spanish and English.
-- Puerto Rico has evolved from an agriculture-based economy in the 1940s, producing sugar, tobacco and coffee, to one now dominated by manufacturing, particularly pharmaceuticals. Manufacturing accounts for about half of the island's GDP. Tourism accounts for less than 10 percent.
