What percentage of construction workers are employed in the United States?

The correct answer is based on statistical data that indicates approximately 5% of the total workforce in the United States is employed within the construction sector. This figure reflects the significant role that construction plays in the economy, providing jobs across a wide range of specialties, including skilled trades, project management, and various support roles. By understanding this percentage, individuals can better appreciate the construction industry's economic impact and its importance as a source of employment.

The other options may seem plausible but do not accurately represent the current labor statistics. For instance, 3% underestimates the sector's contribution, whereas 7% and 10% overstate the proportion of workers employed in construction. Hence, 5% is the most accurate representation, aligning with available labor data and emphasizing construction's significance in the job market.
