Nine of the world's top 10 most walkable cities are in Europe, according to a report by a price comparison website.

Compare the Market Australia found that the German city of Munich is the most walkable city in the world.

But what does "walkable" mean?

For 53 cities, the company looked at how safe the place is, and the amount of walking and bike trails it has.

It also looked at the quality and price of public transport, the percentage of people who live near services and car-free spaces, and the amount of rain the city gets.

So, "walkable" here really means how easy it is to get around without using a car.

The site said 86% of people in Munich live less than 1 kilometer from a car-free space. And although its public transport isn't cheap, the city is thought to be a safe place to walk around.

The top five cities are all in Europe, with Milan in second place. Warsaw, Helsinki and Paris came next.

The only city in the top 10 that's outside of Europe is Tokyo, which was in sixth place.

The Japanese capital has a good public transport system and lots of walking trails.

The US is often thought of as a place where the car is "king," so it's perhaps no surprise that there weren't many US cities in the report. New York was the most walkable US city, in 34th place.

Houston and Dallas were named among the world's least walkable cities, with Johannesburg in South Africa found to be the least walkable of all.
