Educational worksheet on population density featuring maps and data for continents.

Let's solve this Population Density worksheet step by step.

🔷 What is Population Density?

Population Density =
$$
\frac{\text{Population}}{\text{Area}} \quad \text{(in people per km²)}
$$

We'll calculate the population density for each continent and then answer the questions.

## ✔ Step 1: Calculate Population Densities

🌍 Africa

- Population = 1.1 billion = 1,100,000,000
- Area = 30,000,000 km²

$$
\text{Density} = \frac{1,100,000,000}{30,000,000} = 36.67 \text{ people/km²}
$$

✔ Africa: 36.7 people/km² (rounded to 1 decimal place)

---

🌎 South America

- Population = 387 million = 387,000,000
- Area = 17,800,000 km²

$$
\text{Density} = \frac{387,000,000}{17,800,000} ≈ 21.74 \text{ people/km²}
$$

✔ South America: 21.7 people/km²

---

🌍 North America

- Population = 550 million = 550,000,000
- Area = 24,700,000 km²

$$
\text{Density} = \frac{550,000,000}{24,700,000} ≈ 22.27 \text{ people/km²}
$$

✔ North America: 22.3 people/km²

---

🌍 Europe

Given:
- Population Density = 72.9 people/km²
- Area = 10,180,000 km²

We can find the population:

$$
\text{Population} = \text{Density} × \text{Area} = 72.9 × 10,180,000
$$

$$
= 740,822,000 ≈ 741 \text{ million}
$$

✔ Europe: Population = 741 million

---

🌏 Asia

Given:
- Population = 4.4 billion = 4,400,000,000
- Population Density = 98.7 people/km²

We can find the area:

$$
\text{Area} = \frac{\text{Population}}{\text{Density}} = \frac{4,400,000,000}{98.7} ≈ 44,580,000 \text{ km²}
$$

✔ Asia: Area ≈ 44,580,000 km²

## ✔ Summary Table

| Continent | Population | Area (km²) | Population Density (people/km²) |
|----------------|----------------|------------------|----------------------------------|
| Africa | 1.1 billion | 30,000,000 | 36.7 |
| South America | 387 million | 17,800,000 | 21.7 |
| North America | 550 million | 24,700,000 | 22.3 |
| Europe | 741 million | 10,180,000 | 72.9 |
| Asia | 4.4 billion | 44,580,000 | 98.7 |

## ✔ Answer the Questions

1) Which continent is the most densely populated?

👉 Asia with 98.7 people/km²

✔ Answer: Asia

---

2) Which continent is the least densely populated?

👉 South America with 21.7 people/km² (lowest among all)

✔ Answer: South America

---

3) Use the internet to find out which countries are the most and least densely populated in the world. What are their population densities?

This is a research question. Here’s what you’d typically find:

#### 🔹 Most Densely Populated Country:
- Monaco – about 19,000 people/km²
- Other dense countries: Singapore (~8,300), Bahrain (~1,800), Malta (~1,400)

#### 🔹 Least Densely Populated Country:
- Mongolia – about 2 people/km²
- Others: Greenland (~0.03), Namibia (~4), Australia (~4)

✔ Example answer:
> The most densely populated country is Monaco, with a population density of about 19,000 people per km².
> The least densely populated country is Mongolia, with about 2 people per km².

## ✔ Final Answers

Fill in the blanks:

- Africa: Population Density = 36.7 people/km²
- South America: Population Density = 21.7 people/km²
- North America: Population Density = 22.3 people/km²
- Europe: Population = 741 million
- Asia: Area = 44,580,000 km²
