Printable worksheet for students to calculate and compare population densities of countries and U.S. states.

Since I can't view or access uploaded images directly, I can’t see the specific content of your image. However, based on the text you've provided, it appears to be a Population Density Worksheet with several questions asking for population density calculations and comparisons.

Let me help you solve each problem step by step, assuming the data is as written in your text.

Population Density Formula:

$$
\text{Population Density} = \frac{\text{Population}}{\text{Area (in square miles or km²)}}
$$

We'll use this formula throughout.

1. What is the population density of China?

- Population: 1,321,851,888
- Area: 3,705,382 square miles

$$
\text{Density} = \frac{1,321,851,888}{3,705,382} \approx 356.8 \text{ people per square mile}
$$

✔ Answer: ~357 people per square mile

2. What is the population density of the U.S.?

- Population: 301,139,407
- Area: 3,615,403 square miles

$$
\text{Density} = \frac{301,139,407}{3,615,403} \approx 83.3 \text{ people per square mile}
$$

✔ Answer: ~83 people per square mile

3. What is the population density of Mexico?

- Population: 125,473
- Area: 1.2 million square miles → 1,200,000 sq mi

Wait — this seems inconsistent. The population of Mexico is much higher than 125,473. That’s likely a typo. Let's assume the correct population is 125,473,000 (which is close to actual data).

So:
$$
\text{Density} = \frac{125,473,000}{1,200,000} \approx 104.6 \text{ people per square mile}
$$

✔ Answer: ~105 people per square mile

> ⚠️ Note: If the population is actually 125,473, then density would be ~0.1 people/sq mi, which is unrealistic. So we assume it's 125,473,000.

4. What is the population density of Canada?

- Population: 35,556,300
- Area: 3,850,885 square miles

$$
\text{Density} = \frac{35,556,300}{3,850,885} \approx 9.23 \text{ people per square mile}
$$

✔ Answer: ~9 people per square mile

5. Which of the four countries above has the highest population density? Which has the lowest?

From our calculations:

| Country | Density (people/sq mi) |
|-------------|------------------------|
| China | ~357 |
| U.S. | ~83 |
| Mexico | ~105 |
| Canada | ~9 |

✔ Highest: China
✔ Lowest: Canada

6. Which country has the largest land area? Which has the smallest?

- China: 3,705,382 sq mi
- U.S.: 3,615,403 sq mi
- Mexico: 1,200,000 sq mi
- Canada: 3,850,885 sq mi

✔ Largest land area: Canada
✔ Smallest land area: Mexico

---

7. What is the population density of Wyoming?

- Population: 49,750
- Area: 97,055 square miles

$$
\text{Density} = \frac{49,750}{97,055} \approx 0.51 \text{ people per square mile}
$$

✔ Answer: ~0.5 people per square mile

---

8. What is the population density of Pennsylvania?

- Population: 12,281,094
- Area: 46,071 square miles

$$
\text{Density} = \frac{12,281,094}{46,071} \approx 266.6 \text{ people per square mile}
$$

✔ Answer: ~267 people per square mile

---

9. Which state has a higher population density: Pennsylvania or Wyoming?

- PA: ~267 people/sq mi
- Wyoming: ~0.5 people/sq mi

✔ Answer: Pennsylvania has a much higher population density.

10. Which two countries appear to have the largest areas of high population density? (Hint: If you don’t know which countries they are, look at the world map on pages 4A–6A in your book.)

This question is qualitative and requires geographic knowledge.

High population density areas are typically found in:

- China – especially along the eastern coast (e.g., Beijing, Shanghai)
- India – not listed, but if it were, it would be top
- Japan, Germany, Netherlands, etc.

But from the list given: China and the United States (especially coastal cities like New York, Los Angeles)

However, China has the highest density among these.

Also, Mexico has relatively high density in urban areas like Mexico City.

✔ Likely answer: China and the United States

(Or possibly China and Mexico, depending on context.)

But since China and U.S. both have large populations and moderate-to-high densities, and China clearly leads.

✔ Best answer: China and the United States

---

11. The area around which city in the United States seems to have the highest population density?

This is a general knowledge question.

The most densely populated urban area in the U.S. is:

✔ New York City (especially Manhattan)

Other dense areas: San Francisco, Boston, Washington D.C., but New York City is the most densely populated.

✔ Answer: New York City

✔ Final Answers Summary:

1. China: ~357 people/sq mi
2. U.S.: ~83 people/sq mi
3. Mexico: ~105 people/sq mi *(assuming population is 125,473,000)*
4. Canada: ~9 people/sq mi
5. Highest: China; Lowest: Canada
6. Largest land area: Canada; Smallest: Mexico
7. Wyoming: ~0.5 people/sq mi
8. Pennsylvania: ~267 people/sq mi
9. Higher density: Pennsylvania
10. Countries with high density: China and United States
11. City: New York City
