American Samoa Transport Stats
Definitions
- Airports: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control.
- Airports > Per capita: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control. Per capita figures expressed per 1 million population.
- Airports > With paved runways > Over 3,047 m: This entry is derived from Transport > Airports > With paved runways, which gives the total number of airports with paved runways (concrete or asphalt surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.
- Airports > With paved runways > Total: Total number of airports with paved runways (concrete or asphalt surfaces)
- Airports > With unpaved runways > Total: Total number of airports with useable unpaved runways (grass, dirt, sand, or gravel surfaces)
- Airports per million: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control. Figures expressed per million population for the same year.

- Highways > Paved > Per capita: total length of the paved parts of the highway system Per capita figures expressed per 1,000 population.
- Highways > Total: total length of the highway system
- Highways > Total > Per capita: total length of the highway system Per capita figures expressed per 1,000 population.
- Highways > Total per 1000: total length of the highway system. Figures expressed per thousand population for the same year.
- Ports and harbors: The major ports and harbors selected on the basis of overall importance to each country. This is determined by evaluating a number of factors (e.g., dollar value of goods handled, gross tonnage, facilities, and military significance).
- Ports and terminals: This entry lists major ports and terminals primarily on the basis of the amount of cargo tonnage shipped through the facilities on an annual basis. In some instances, the number of containers handled or ship visits were also considered.
- Road network length > Km: Length of road network in kilometers in European Union countries.
- Roadways > Total: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
