The World Happiness Report, a landmark survey of the state of global happiness, ranks countries by their happiness levels, while the UN Sustainable Development Solutions Network develops solutions to challenges in sustainable development. Combining insights from these sources, we can explore the most happiest and unhappiest countries in the world, providing a snapshot of global well-being and the factors that influence it.

Countries struggling with these issues tend to rank lower in the World Happiness Report. These nations, often facing conflicts, economic challenges, or both, show how critical governance, community support, and stability are to collective well-being.
