To calculate the population density of Phoenix, Arizona, we can follow these steps:
### Step 1: Identify the necessary data
We have two pieces of information:
- Population: 1,445,632 people
- Area: 450 square miles
### Step 2: Use the population density formula
The formula for population density is:
\[
\text{Population Density} = \frac{\text{Population}}{\text{Area}}
\]
### Step 3: Plug in the values
Substituting the known values into the formula gives us:
\[
\text{Population Density} = \frac{1,445,632}{450}
\]
### Step 4: Perform the calculation
Now we calculate the population density:
\[
\text{Population Density} = 3,211.41 \, \text{people per square mile}
\]
Rounding to the nearest whole number, the population density of Phoenix, Arizona, is approximately **3,211 people per square mile**.

### Question 9: Policy Implications of Population Density in Phoenix
The information about Phoenix's population density can be significant for addressing various policy issues, including transportation concerns and disease spread.
**Transportation Concerns:**
High population density typically means greater demand for public transportation, road infrastructure, and traffic management. City planners can use data about population density to:
- Allocate resources effectively for public transit systems to ensure they serve densely populated areas efficiently.
- Identify areas where traffic congestion may be most severe, leading to infrastructure improvements or the development of alternative transportation initiatives, such as bike lanes or pedestrian pathways.
**Disease Spread:**
When considering public health, population density plays a crucial role in understanding and controlling the spread of diseases. For example:
- Higher population density can facilitate quicker transmission of infectious diseases due to increased interactions among individuals.
- Health officials can prioritize vaccination campaigns, health resources, and educational programs in more densely populated areas to manage potential outbreaks effectively.
In both cases, understanding the population density of Phoenix helps policymakers make informed decisions to improve transportation infrastructure and health outcomes for the residents.
