The foreignness of English in Puerto Rico is greater in magnitude than it was in any state at any time in our national experience, including the examples listed. Census data show that just 20 percent of the island’s residents speak English fluently. By comparison, California has the lowest proficiency rate among the 50 states, but its 80 percent proficiency rate dwarfs Puerto Rico’s. The deeply rooted preference for Spanish makes Puerto Rico’s 1993 elevation of English to “co-official” status practically irrelevant. Authentic “official English” policies increase English learning, but they will not work when English is merely an add-on to a pre-existing official language that is spoken in 95 percent of homes.
