The world’s 50 largest container ports and airport terminals have a concentration level in their distribution, with container ports having the highest level, as depicted on its Lorenz curve. The 10 largest terminals account 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 handle 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.
