Labor Force Participation Rate

Steps:

• Identify working-age population as people aged 15-64 eligible to work.
• Define labor force as those employed or actively seeking employment.
• Compute participation rate as (labor force / working-age population) × 100.
• Recognize typical global or national rate from economic data.

Why C is correct:

• Economic definitions show the labor force participation rate for working-age adults averages around 80% in many developed economies, per standard labor statistics.

Why the others are wrong:

• A: 30% underestimates; it ignores most employable adults actively working or job-hunting.
• B: 70% is too low for full participation; it fits older data but not current norms.
• D: 90% overestimates; it assumes near-universal involvement, excluding students, retirees, and discouraged workers.

Final answer: C
