Disparity within the Spanish healthcare system has been prevalent since the inception of the democracy after the fall of Franco. This disparity has particularly affected the poorer regions of Spain, which did not have the resources or infrastructure of the wealthier regions, such as the Basque Country and Catalonia. This thesis sought to analyze the policies of the national-level governments of the Popular Party's Jose Maria Aznar (1996-2000 and 2000-2004) and social democratic leader Jose Luis Rodriguez Zapatero (2004-present). After research on the policies of the governments and collection of data on healthcare expenditure per capita at each time point (the status of the healthcare system in 1996 before the first Aznar government and at the end of each government's term) in all regions of Spain, it was found that the PSOE government of Zapatero was more successful in promoting parity than the PP governments of Aznar
