To calculate the population density, you can use the formula:
\[ \text{Population Density} = \frac{\text{Population}}{\text{Area}} \]
Given:
- Population = 748,814,048 people
- Area = 3,930,000 square miles
Substituting the values into the formula gives:
\[ \text{Population Density} = \frac{748,814,048}{3,930,000} \approx 190.54 \]
Therefore, the correct population density of Europe on February 4, 2023, is approximately 190.54 people per square mile.
