World Population Review | Healthiest Countries 2021 |

2021 Population: 60,367,477
All countries aren’t created equal, and there are a variety of factors that contribute to healthy, happy countries – as well as factors that contribute to unhealthy countries. Typically, the healthiest countries are those that are developed. These countries have lower pollution rates, access to quality health care, and access to clean, safe drinking water. On the other hand, unhealthy countries may not have access to clean drinking water or health care. Diseases run rampant. Pollution may be high, leading to health problems, illnesses, and death. The life expectancy of the residents of these countries is low, and infant mortality is high. Quality of life is dramatically lower than in the more developed countries.

The Bloomberg Global Health Index takes a look at several of these factors to rank the healthiest (and unhealthiest) countries in the world. The factors that are used to rank the countries include:

  • Health risks (tobacco use, high blood pressure, obesity)
  • Availability of clean water
  • Life expectancy
  • Malnutrition
  • Causes of death
Using these factors, the index ranks each country out of a score of 100. According to the 2019 ranking, Spain is considered to have the healthiest people globally, with a score of 92.75. Spain boasts a life expectancy of 83.5 years, which is expected to rise to 85.8 by 2040 and be the highest in the world.
