Global Connectivity Ranking
The Global Connectivity Ranking from Rome2rio includes a beautiful interactive data visualization showing how connected we are on a global scale. Above you can see the direct flight connections from London, the most connected city on Earth.
Just how connected are our cities? How do we measure such connections? How do these connections change over time?
To answer these questions, my research team at KPMG collaborated with Rome2rio to produce the Global Connectivity Ranking. We ranked all 1,212 cities on the planet which operate international airports.
The Rome2rio Global Connectivity Ranking reflects the number of international cities that a city is connected to through direct flights. It measures connections from city to city - not airport to airport. For example, the connection count for London reflects how many cities outside the UK that can be reached from any of London's 6 international airports. Rankings were computed using Rome2rio's global transit data from April 2014 and January 2016.
Choose any city on the list to animate to direct flight connections. The size of the bubbles over each city also represent the total number of connections from that city.
The default is the world view, but can also choose to focus on a single continent. Here you can see the connection from Chicago when zoomed in to only North America.
