The following dissertation is about pastoral care for the aging population of Cuba. It proposes an alternative methodology of study inside the field of Practical Theology. It also gives a deep analysis of the vast universe of the Cuban population and how it is getting older with the passing of years. This study aims to show how aging is affecting the reality of Cuba, how this produces a huge impact upon the church, and the urgent pastoral response that must occur from the Christianity communities. The delimited historical period 2005 until 2015 had an evident manifestation among the aging e population in Cuba. The three oldest municipalities of Havana, the Capital of Cuba, are: “Playa”, “Plaza de la Revolucion” and “Diez de Octubre”. These communities experienced a large demographic transformation that resulted in a large aging population. This dissertation explores how this demographic aging has impacted the lives of the church.
