The statement is false. The largest component of GDP is private consumption, or simply: consumption.

Explanation:

Consumption includes all purchases of goods and services made by individuals and households except for the purchase of new houses (these are considered investments).

In the U. S., consumption accounts for around 70% of GDP. This is why some economists say that the U. S. is a consumer-based economy.
