The economic health of a country plays a significant role in shaping the lifestyle, convenience, and opportunities available to its citizens. A central measure of this economic health is the Gross National Income (GNI) per capita, a metric that helps us understand the average income of a country's citizens, considering both domestic and foreign outputs. High-income countries, as classified by the World Bank, boast a GNI per capita of $13,206 or more. These nations, often seen as benchmarks of prosperity, provide insightful data about the relationship between economic health and the quality of life.
