Transportation Economic Trends
Contribution of Transportation to the Economy:
Final Demand Attributed to Transportation
Transportation contributes directly to the economy. This page discusses gross domestic product (GDP)—a measure of economic activity—attributed to the demand for transportation relative to other goods and services. The contribution of transportation services to GDP is an alternative measure of transportation's direct contribution to the economy.
2022 Year-in-Review
- In 2022, the demand for transportation ($2.3 trillion) accounted for 9.0 percent of GDP.
- Household purchases of motor vehicles and parts accounted for the largest portion (31.7 percent) of the demand for transportation in 2022.
- Adjusted for inflation, the demand for transportation decreased by 5.1 percent in 2022, marking the second largest year-over-year decline since 2002. The largest year-over-year decrease occurred in 2020 (16.6 percent).
- The demand for transportation decreased in 2022 due to declines in personal consumption expenditures of motor vehicles and parts (6.7 percent), motor vehicle insurance (2.1 percent), and government investment in transportation (1.9 percent). Imports of transportation-related goods and services also exceeded transportation related exports more in 2022 than in 2021, which further decreased the demand for transportation in 2022.
- Retail dealers' inventories of motor vehicles and parts increased in 2022 and became positive in value. This means retail dealers bought more motor vehicles and parts than they sold and added to their inventories.
- More transportation-related goods and services were imported than exported in 2022; the largest difference on record (with records beginning in 2002).
Gross Domestic Product Attributed to the Demand for Transportation
Gross Domestic Product (GDP) measures economic activity, tallying expenditures on all final goods and services purchased by
persons, businesses, governments, and foreigners in a country. Expenditures fall into five categories, with each a measure of the final demand for: healthcare, housing, food, education, and all other goods and services.
Expenditures on transportation (GDP attributed to the demand for transportation) are less than all categories except education and hence account for a smaller portion of GDP. However, transportation plays a vital role in the economy, as measured by GDP, by making economic activity possible. For example, transportation delivers the raw materials businesses need to produce goods and services.
Final demand attributed to transportation (shown here) offers one way to measure transportation's contribution to GDP. The contribution of transportation services to GDP offers another way.
Components of the Demand for Transportation
The demand for transportation is the sum of:
- Personal (household) consumption expenditures on motor vehicles and parts; motor vehicle fuels, lubricants, and fluids; motor vehicle and other transportation insurance; and transportation services (e.g., passenger airfare);
- Government investment in transportation infrastructure and purchases of transportation goods and services;
- Private domestic investment in transportation infrastructure and equipment;
- The change in retailers’ inventories of motor vehicles and parts; and
- Net exports (exports minus imports) related to transportation goods and services.
Personal consumption of motor vehicles and parts accounts for the largest component of the demand for transportation.
