“TOP 20 Healthiest Countries in the World”
Top 20 healthiest countries in the world are based on Bloomberg Rankings which included health scores and health-risk scores on 145 countries surveyed, and with populations of at least 1 million. Health scores were based on factors like infant mortality, life expectancy at birth and causes of death. The survey also included the proportion of those with high cholesterol, percentage of underweight kids, and access to sanitation in the country among others.
The formula to determine the country’s rank is subtract the risk score from the health score.
