GDP Per Capita Measures Average Economic Output

Steps:

• Recall that GDP measures a country's total economic output.
• Understand "per head" or "per capita" means dividing by the number of people to find average output per person.
• Identify the standard divisor as the total population, including all residents.
• Confirm this yields GDP per capita, a key economic indicator.

Why C is correct:

• GDP per capita is defined as total GDP divided by total population, per the formula: GDP per capita = GDP / Total Population.

Why the others are wrong:

• A: Adult population excludes children and elderly, skewing the average upward.
• B: Dependent population (non-workers) is too narrow and not used in standard calculations.
• D: Working population focuses on labor force, relevant for productivity but not per capita GDP.

Final answer: C
