For this purpose, the role of globalization and democracy in life expectancy is empirically investigated in 16 low-income countries over the period 1970–2017. These SDGs are “Good Health and Well-Being” (SDG3) and “Partnerships for the Goals” (SDG17). Therefore, the main purpose of this study is to investigate whether two sustainable development goals (SDGs) of the UN are contradictory or supporting each other in low-income countries. It has been observed in the literature that possible contradictions between these goals are ignored. However, achieving all of these goals is only possible if the goals are consistent with each other. The 17 Sustainable Development Goals announced by the United Nations are important guides for the development processes of developing countries.
