Using the A=Pert formula estimate the population size of the Philippines in the next 20 years. The current population as of 2024 is 119,106,224 and the growing rate per year us 1.9%. Also compare for the population density in the same year( use the formula: population density= number of people)

Let's estimate the population size of the Philippines in the next 20 years using the \( A = Pe^{rt} \) formula.

### 1. **Given Values**:
- **Current Population (P)**: 119,106,224 (as of 2024)
- **Growth Rate (r)**: 1.9% per year (convert to decimal: \( r = 0.019 \))
- **Time (t)**: 20 years
- **Land Area of the Philippines**: 300,000 square kilometers (needed for population density calculation).

### 2. **Population Estimate**:

Using the formula \( A = Pe^{rt} \):

\[
A = 119,106,224 \times e^{(0.019 \times 20)}
\]

First, compute the exponential part:

\[
e^{(0.019 \times 20)} = e^{0.38} \approx 1.462
\]

So:

\[
A \approx 119,106,224 \times 1.462 \approx 174,116,311
\]

### 3. **Population Density**:

To calculate the population density in 2044, use the population density formula:

\[
\text{Population Density} = \frac{\text{Population}}{\text{Land Area}}
\]

For 2044:

\[
\text{Population Density} = \frac{174,116,311}{300,000} \approx 580 \text{ people per square kilometer}
\]

### **Summary**:
- **Estimated Population in 2044**: Approximately 174,116,311.
- **Estimated Population Density in 2044**: Approximately 580 people per square kilometer.

### **Relative Questions**:
1. How will a population increase of this magnitude affect the economy of the Philippines?
2. What measures can be taken to manage the increasing population density in urban areas?
3. How does the population growth rate compare to other countries in Southeast Asia?
4. What would happen if the growth rate slowed to 1.5% per year?
5. How does population growth impact environmental sustainability in the Philippines?

### **Tip**:
When projecting population growth over longer periods, consider that growth rates can fluctuate due to factors such as changes in birth rates, migration, and government policies.

Learn how to estimate the population size of the Philippines in 2044 using the A=Pert formula. Given a current population of 119,106,224 in 2024 and an annual growth rate of 1.9%, calculate the future population and population density. Explore implications of population growth on economic and urban planning in the Philippines.
