This paper utilizes both narrative analysis and statistical techniques in an investigation of the principle of cumulative causation to explain underdevelopment, relative poverty and spatial disparities on Hispaniola. The events that explain this process in the underdevelopment of Hispaniola have resulted in a tragically downward spiral in Haiti, placing its future in great peril. The Dominican Republic is relatively better off than its neighbor; however, the shortage of basic services, poverty and malnutrition are quite prevalent in the Dominican Republic.
