Water transportation workers held more than 72,000 jobs in 2004. The total number who worked at some point in the year was perhaps twice as large because many merchant marine officers and seamen worked only part of the year. The following tabulation shows employment in the occupations that make up this group:
|Captains, mates, and pilots of water vessels
|Sailors and marine oilers
About 33 percent of all workers were employed in water transportation services. About 17 percent worked in inland water transportationprimarily the Mississippi River systemwhile the other 16 percent were employed in water transportation on the deep seas, along the coasts, and on the Great Lakes. Another 25 percent worked in establishments related to port and harbor operations, marine cargo handling, or navigational services to shipping. The Federal government employed approximately 5 percent of all water transportation workers, most of whom worked on supply ships and are Civilian Mariners of the Department Navy’s Military Sealift Command.
