High-income economies are countries with a high gross national income (GNI) per capita, typically above $12,536, as defined by the World Bank. These economies often have advanced technological infrastructure, a well-developed service sector, and a high standard of living for their citizens. Examples of high-income economies include the United States, Germany, and Japan. These nations usually invest significantly in education, healthcare, and innovation, contributing to their economic stability and growth. High-income economies also tend to have lower unemployment rates and higher levels of productivity compared to lower-income countries.
