Island Paradox is the first comprehensive, census-based portrait of social and economic life in Puerto Rico. During its nearly fiftyyears as a U. S. commonwealth, the relationship between Puerto Rico's small, developing economy and the vastly larger, more industrialized United States has triggered profound changes in the island's industry and labor force. Puerto Rico has been deeply affected by the constant flow of its people to and from the mainland, and by the influx of immigrant workers from other nations. Distinguished economists Francisco Rivera-Batiz and Carlos Santiago provide the latest data on the socioeconomic status of Puerto Rico today, and examine current conditions within the context of the major trends of the past two decades. sland Paradox describes many improvements in Puerto Rico's standard of living, including rising per-capita income, longer life expectancies, greater educational attainment, and increased job prospects for women. But it also discusses the devastating surge in unemployment. Rapid urbanization and a vanishing agricultural sector have led to severe inequality, as family income has become increasingly dependent on education and geographic location. Although Puerto Rico's close ties to the United States were the major source of the island's economic growth prior to 1970, they have also been at the root of recent hardships. Puerto Rico's trade andbusiness transactions remain predominantly with the United States, but changes in federal tax, social, and budgetary policies, along with international agreements such as NAFTA, now threaten to alter the economic ties between the island and the mainland.
