how your travel score is calculated:

Based on the grid cells you've selected, three numbers are calculated:

The percentage of the world's countries that you've visited
The share of the world's population that lives in these areas
The share of the earth's land surface that lies inside the selected grid cells

The overall travel score is the mean of these three numbers. Of course this calculation method is kind of arbitrary. It's just my approach to measure how much of the world a person has seen.

where the data comes from:

State boundaries by Natural Earth (Tom Patterson, Nathaniel Vaughn Kelso & many others)

Place labels by Natural Earth (Tom Patterson, Nathaniel Vaughn Kelso & many others)
1:110m Cultural Vectors - Populated places, v. 2.0.0 (2012) link

Population data by CIESIN at Columbia University

about this project:

This project was realized by PatrickStotz (@PatrickStotz).

I'm endlessly fascinated by maps, dataviz & urbanism, plus I love to travel! Having a large world map with pin needles hanging in our living room, I always wanted to build a modern, interactive version of this map.

If you're interested in the technical details behind this project take a look at the project description on mappable.info
