Life expectancy is an indicator showing how many years a child born in a given year is expected to live on average. Because it reflects medical standards, nutritional status, and living environment, it is used as an important indicator to measure a country's level of development. The top positions in the ranking are occupied by developed countries with well-established healthcare systems and economic prosperity, such as Switzerland, Japan, and Singapore. Conversely, lower positions include many countries in sub-Saharan Africa and others facing challenges such as infectious disease outbreaks, limited healthcare access, and poverty. By comparing life expectancy across countries, we can understand global health disparities.
