This table provides metadata for the actual indicator available from US statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from US statistics, this table should be consulted for information on national methodology and other US-specific metadata information.
Actual indicator available | Passenger Data: Passenger-kilometers by mode in millions; Freight Data - Metric tonnage of freight shipments by mode in millions. |
---|---|
Actual indicator available - description | Passenger Data: Number of passengers multiplied by number of kilometers traveled; Freight Data: Tonnage of total freight shipped |
Date of national source publication | Passenger - July 2017, Freight - April 2017 |
Method of computation | Passenger data – number of passengers multiplied by the distance traveled. Freight data – the Freight Analysis Framework incorporates data from the 2012 Commodity Flow Survey, Transborder Freight Data, Foreign Trade Statistics, and a combination of sources for individual sectors including agriculture, energy extraction, construction, and other sectors. Both passenger and freight data have been converted to metric units. |
Periodicity | Annual and monthly data |
Scheduled update by national source | Passenger - July 2018, Freight - Not currently scheduled |
U.S. method of computation | |
Comments and limitations | Rail passenger-kilometer data are Amtrak only. Commuter rail, light rail and subways are included under transit. Amtrak data are a sum of the passenger-kilometer data for the twelve months of each calendar year. Air passenger-kilometer data are for certified air carriers in domestic service. |
Date metadata updated | October 2017 |
Disaggregation geography | United States - Passenger data includes travel in the United States. Freight data includes domestic shipments and the U.S. portion of foreign shipments. |
Unit of measurement | Passenger-kilometers, metric tonnes |
Disaggregation categories | Mode of transportation |
