The motor vehicle industry is an important component of the manufacturing output of the United States. In 2001, motor vehicle manufacturing accounted for 19.8 percent of all durable goods manufacturing in the United States. (NIPA table 1.3)

The domestic production level of motor vehicles is dependent on other factors beyond the domestic demand for motor vehicle transportation: Foreign trade is playing an increasingly important role in the domestic automotive market. The value in real terms (1996 dollars) of U.S. motor vehicle-related net imports increased from 50.7 billion dollars in 1992 to 114.0 billion dollars in 2001. (NIPA table 4.4)

The production of medium and heavy trucks can be used as a gauge of commercial expectations from the standpoint of shipping capacity. Shippers may buy more road freight handling vehicles to expand capacity to meet an expected increase in demand. Light trucks and cars are used primarily for personal transportation. The production of light trucks has grown the most since 1992. Income growth over the past decade has helped drive consumer demand for more expensive personal transportation like SUV's.

Motor Vehicle Assemblies Jul-02 Aug-02
Light trucks (millions of units) 7.50   7.56
Percent change from previous month 4.84   0.89
Cars (millions of units) 5.45   5.07
Percent change from previous month 3.46  -6.89

NOTES: The mid-1998 dip in assemblies was caused by a strike at General Motors in June and July.

An assembly is equal to the assembly of the entire vehicle.
