Ports of the United States
The Ports of the United States handle more than 2 billion metric tons of domestic and import/export cargo annually. By 2020, the total volume of cargo shipped by water is expected to be double that of 2000 volumes. American ports are responsible for moving over 99 percent of the country's overseas cargo.
U.S. ports handle a wide variety of goods that are critical to the global economy, including petroleum, grain, steel, automobiles, and containerized goods. Reports from individual ports indicate that approximately 4.6 million automobiles (imports and exports) passed through American ports in 2006.
Employment
In addition to handling goods from all over the world, U.S. ports play a key role in creating jobs. For every $1 billion in exports about 15,000 port jobs are created. The figure swells to 30,000-45,000 when taking into account jobs to support new products and personnel.
Total port-related employment in the United States was estimated at 8.4 million people in 2006. Of this total, 1.4 million were employed in providing goods and services to ports (such as longshore, stevedore, and security personnel). The remaining 7 million were employed in import- and export-related activities (such as transportation, warehousing, and distribution). Port activities were also responsible for bringing in $102.8 billion in federal, state and local taxes in 2006.
