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 $ GDP: Total number of airports. Runways must be useable, but may be unpaved. May not have facilities for refuelling, maintenance, or air traffic control. Per $ GDP figures expressed per 1 billion $ gross domestic product.
- 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 > 1,524 to 2,437 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 > Over 3,047 m per million people: 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).

Figures expressed per million people for the same year.
- Airports > With paved runways > Total: Total number of airports with paved runways (concrete or asphalt surfaces)
- Airports > With paved runways > Total > Per $ GDP: Total number of airports with paved runways (concrete or asphalt surfaces) Per $ GDP figures expressed per 1 billion $ gross domestic product.

- 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.
- 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.
- Roadways > Total: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
- Roadways > Unpaved: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
- Liner shipping connectivity index > Maximum value in 2004 = 100: The Liner Shipping Connectivity Index captures how well countries are connected to global shipping networks. It is computed by the United Nations Conference on Trade and Development (UNCTAD) based on five components of the maritime transport sector: number of ships, their container-carrying capacity, maximum vessel size, number of services, and number of companies that deploy container ships in a country's ports. For each component a country's value is divided by the maximum value of each component in 2004, the five components are averaged for each country, and the average is divided by the maximum average for 2004 and multiplied by 100. The index generates a value of 100 for the country with the highest average index in 2004. . The underlying data come from Containerisation International Online."
