Population density & demographics

Answers and reasoning. Review before teaching.

1. A region has a population of 1040 people and a land area of 10 km². Calculate its population density.
104 people/km²
Population density = population ÷ area = 1040 ÷ 10 = 104 people/km².
2. A region has a population of 817 people and a land area of 19 km². Calculate its population density.
43 people/km²
Population density = population ÷ area = 817 ÷ 19 = 43 people/km².
3. A region has a population of 405 people and a land area of 9 km². Calculate its population density.
45 people/km²
Population density = population ÷ area = 405 ÷ 9 = 45 people/km².
4. A region has a population of 261 people and a land area of 3 km². Calculate its population density.
87 people/km²
Population density = population ÷ area = 261 ÷ 3 = 87 people/km².
5. A region has a population of 623 people and a land area of 7 km². Calculate its population density.
89 people/km²
Population density = population ÷ area = 623 ÷ 7 = 89 people/km².
6. A region has a population of 168 people and a land area of 8 km². Calculate its population density.
21 people/km²
Population density = population ÷ area = 168 ÷ 8 = 21 people/km².
7. A region has a population of 1666 people and a land area of 17 km². Calculate its population density.
98 people/km²
Population density = population ÷ area = 1666 ÷ 17 = 98 people/km².
8. A region has a population of 650 people and a land area of 13 km². Calculate its population density.
50 people/km²
Population density = population ÷ area = 650 ÷ 13 = 50 people/km².
9. A region has a population of 2800 people and a land area of 25 km². Calculate its population density.
112 people/km²
Population density = population ÷ area = 2800 ÷ 25 = 112 people/km².
10. A region has a population of 1386 people and a land area of 21 km². Calculate its population density.
66 people/km²
Population density = population ÷ area = 1386 ÷ 21 = 66 people/km².
11. A region has a population of 214 people and a land area of 2 km². Calculate its population density.
107 people/km²
Population density = population ÷ area = 214 ÷ 2 = 107 people/km².
12. A region has a population of 372 people and a land area of 3 km². Calculate its population density.
124 people/km²
Population density = population ÷ area = 372 ÷ 3 = 124 people/km².
