promoted method of contraception in Puerto Rico and was legitimized by concerns of population, which can be associated with the same concerns of race and class that date back to the island's annexation. After the US gained ownership of Puerto Rico, it was viewed as a province in urgent need of a way to prevent greater poverty and population rates. This heavily influenced the US decision to begin sterilizing Puerto Rican women and implementing experimental birth control methods. Puerto Rican women in particular have served as test subjects for various contraceptive studies in the United States, of which included involuntary sterilization. Many Puerto Rican women were sterilized from the 1930s to the 1970s in order to decrease poverty and population growth in Puerto Rico. Population and poverty crisis Concerns about the population density in Puerto Rico can be traced back to 1898 when Puerto Rico became a US colony. These concerns from scholars, scientist, and government officials inform the thought process behind the association between poverty, health, and economy with population throughout the 20th century. When Americans began to occupy the island of Puerto Rico, they asserted more than their ideals and beliefs. American colonizers asserted absolute dominance over Puerto Rico due to the idea of Manifest Destiny, which greatly shifted the dynamics of the island. The U.S. capitalized on the fact that Puerto Rico utilized a large fraction of its resources to gain independence from Spain, which left the island's economy depleted. During this time, many Puerto Ricans lost land while their natural resources became exploited. In the mid-1920s, Puerto Rico's dependency on the production of sugar, devastated the island when the sugar market collapsed. Additionally, the nation-wide economic depression in 1927 exacerbated the effects of this collapse as well as the overall stability of the island. In 1928, Puerto Rico suffered the consequences of a hurricane in San Felipe. The Okeechobee Hurricane resulted in over 300 deaths and property damages ranging from $50-$80 million, while the agricultural market also suffered. In the 1930s, Puerto Rican citizens began to experience the adverse health effects of tuberculosis, malaria, diarrhea-enteritis, hookworm, and dietary-deficiencies that were responsible for over 40 percent of deaths. This later on gave medical professionals grounds to support sterilization on the island. Furthermore, these factors resulted in immense and widespread poverty. Many Puerto Ricans faced perpetual hunger and growing unemployment rates. In 1930, the median family income was
