The World's Healthiest Countries

Staying healthy can be a challenge for all of us, but it seems to be an easier task when living in some countries compared to others.

We looked at which countries are the healthiest by comparing a number of factors, such as vaccination rates, life expectancy, and potentially risky habits (e.g. smoking, drinking alcohol).

So which country is the healthiest, and which countries need a little improvement?

The World’s Healthiest Countries

Key: Rank Country Life Expectancy at Birth Prevalence of Current Tobacco Smoking Alcohol Consumption in Litres Prevalence of Obesity Among Adults Vaccination Rates Prevalence of Insufficient Physical Activity Among Adults Probability of Premature Death Population Using at Least Basic Drinking-Water Services Score

Methodology:

For each country, we gave a normalised score out of ten on each of the following eight factors. We then took an average of all eight scores for each country (with each factor weighted equally), which was then multiplied by 100 to calculate the overall score.

Vaccination Rates

This number combines the percentage of children receiving the rubella vaccine and the final dose of measles vaccine, taking an average of both rates according to WHO data.

Prevalence of Current Tobacco Smoking

An age standardised percentage of the population aged 15+ who currently use any tobacco product according to WHO data.

Life Expectancy

The life expectancy at birth according to OECD data.

Alcohol Consumption

The number of litres of pure alcohol sold per person aged 15+ according to OECD data.

Prevalence of Insufficient Physical
Activity Among Adults

The percentage of adults deemed to have insufficient physical activity according to WHO data.

Probability of Premature Death

As a percentage, the probability of dying between the ages of 30 and 70 from cardiovascular disease, cancer, diabetes, or chronic respiratory disease according to WHO data.

Population Using at Least Basic
Drinking-Water Services

The percentage of the population who have access to at least basic drinking-water services according to WHO data.

Prevalence of Obesity Among Adults

The percentage of the population with a BMI of 30 or higher according to WHO data.
