The world’s 50 largest container ports and airport terminals have a level of concentration in their distribution, with container ports having the highest level as depicted on its Lorenz curve. The 10 largest terminals accounting for about 49.7% of the traffic handled by the world’s largest 50 container ports. Air passenger traffic has a much lower concentration level (the 10 largest airports handling 30.8% of the traffic of the world’s 50 largest airports), which is reflective of its widespread use as a mode of long distance transportation. Geographical concentration is also significant with most of the activity taking place around East Asia, Western Europe and North America.
