This paper analyzes the opinions on and attitudes towards the end of life among the population residing in Argentina. The data presented are taken from the Second National Survey of Religious Beliefs and Attitudes in Argentina, which was conducted on a multi-stage sample of 2421 cases in 89 districts throughout the country. Opinions about the end of life include positions in favor of euthanasia, requesting life extension through life support technologies, and leaving death to God’s will. Religious beliefs and affiliations prove to be determining variables in the positions taken by Argentine citizens regarding the end of life, death, and euthanasia. Furthermore, among those without any religious affiliation, some positions of autonomy over their bodies stand out: prolonging life and bringing life to an end, which means that their support for euthanasia can be assumed. The data presented here intend to contribute to planning health policies about the end-of-life process. The different views on this process or, in other words, the beliefs, values, and needs of patients and their families have a unique relevance that must be considered in the organization of care settings in end-of-life contexts.
