To calculate the population density, you divide the total population by the total area.
Population density = Population / Area
Given:
- Population = 334,233,854 people
- Area = 3,717,792 square miles
Now, performing the calculation:
\[ \text{Population density} = \frac{334,233,854}{3,717,792} \approx 89.91 \text{ people per square mile} \]
Thus, the population density of the United States on January 1, 2023, was approximately 89.91 people per square mile.
