The Nation’s 128.5 million households, more than 7.9 million business establishments, and 90,000 governmental units are all part of an economy that demands the efficient movement of freight. Freight
transportation has grown over time with the expansion of population and
economic activity within the United States and with the increasing
interdependency of economies across the globe. The U.S. population grew by 16.6
percent between 2000 and 2019, climbing to 328.2 million in 2019. The U.S.
economy measured by gross domestic product (GDP) increased by 45.2 percent in
real terms (inflation adjusted) over the same period. Median household income,
another indicator of economic growth, grew by 2.9 percent in current 2019
dollars between 2000 and 2019. U.S.-international trade grew faster than the
overall economy, reflecting unprecedented global interconnectivity.
Population and gross domestic product (GDP) by region
Although freight moves throughout
the United States, the demand for freight transportation is driven primarily by
the geographic distribution of population and economic activity. Since 2000,
both population and economic activity have grown the fastest in the Southwest. In 2019, the Mideast and Far
West regions have
the highest GDP per capita.

Freight Facts and Figures, developed by the Bureau of
Transportation Statistics, is a collection of charts and statistical
tables about freight transportation in the United States. These
interactive visualizations and tables provide a snapshot of freight
movement; the extent, condition, and performance of the freight
transportation system; the economic implications of freight movement;
and the safety, energy, and environmental impacts of freight
