It’s common knowledge that some countries have higher life expectancies than others, but the city you live in can also affect your health.

Some cities are hard on their residents. In places with poor city planning, for example Lagos, which was called out recently by the Economist Intelligence Unit, public spaces are few, making outdoor activities hard. Lack of infrastructure blocks the streets with cars and the air with pollutants, and residents work long hours for little money.

These are just some of the factors added up by Spotahome, a rental agency. They’ve analyzed data from a range of sources, including the World Health Organization, TripAdvisor and the CIA World Factbook to score each city on health, gym availability and quality, life expectancy, obesity, green space and other elements to make a list to work out which are the world’s healthiest cities.

The list is certainly Euro-centric and sunshine is seen as a positive factor. It does go some way towards suggesting which cities are getting it right in providing a good life for their residents. It may not be surprising to learn that most of the healthiest cities are in northern Europe, known for its people-first approach to city planning. The cities of Australia and Canada also do well. However, the first American city is only in 34th place. The UK doesn’t fare too well either-its only city in the top 50 list is London, in 40th.

Whether you’re planning a wholesome holiday, or simply wondering what your city can do better, the list of the 50 healthiest cities will give you pause for thought. Here are the slender, healthy-eating, clean-aired cities that are getting it right.

What does the list aim to help people do?

A. Form healthy eating habits.

B. Choose a right place for a holiday

C. Become aware of attractiveness of cities

D. Reflect the future of the city planning
