Ranking the most developed countries to live in the world is a complex task, requiring the consideration of numerous factors like economic stability, infrastructure, citizen freedom, safety, and technological advancements. To simplify, we've relied on the United Nations' Human Development Index (HDI) score. HDI incorporates a nation’s economic strength, national income, average life expectancy, welfare, and educational opportunities, offering an objective rating. It's important to note that very small micro-states and principalities are not included in this ranking as they might not be ideal choices for permanent residency.
