Of the 46,997 airports in the world, the top 25 nations have 36,542, while the bottom 25 have only 13. There are 12 countries without even one airport. Five of the top ten nations are in South America, while Venezuela and Chile are 22nd and 23rd. The United States has more airports than the rest of the top ten countries combined, which is good, because 8,534,500 airplanes departed from U.S. airports in 2001. That’s an average of more than 23,000 take-offs per day. This is well ahead of the second-place United Kingdom, which had 985,300 departures in 2001 (a daily average of 2,699). Sierra Leone, at 155th, had only 100 departures. At this rate, it would take 230 years for it to equal the number of departures that occur daily in the United States. |
