To find the population density of each region, you can use the formula:
\[ \text{Population Density} = \frac{\text{Population}}{\text{Land Area}} \]
Calculation for Europe:
- Population: 743.5 million = 743,500,000
- Land area: 3.9 million square miles = 3,900,000
\[ \text{Population Density for Europe} = \frac{743,500,000}{3,900,000} \approx 190.6 \text{ people per square mile} \]
Calculation for the United States:
- Population: 332.4 million = 332,400,000
- Land area: 3.5 million square miles = 3,500,000
\[ \text{Population Density for the United States} = \frac{332,400,000}{3,500,000} \approx 95.0 \text{ people per square mile} \]
Conclusion:
Europe has a population density of approximately 190.6 people per square mile, while the United States has a population density of approximately 95.0 people per square mile.
Thus, the correct answer is:
Europe is more densely populated, with a density of 190.6 people per square mile.
