Population density & demographics

Answers and reasoning. Review before teaching.

1. A region has a population of 840 people and a land area of 21 km². Calculate its population density.
40 people/km²
Population density = population ÷ area = 840 ÷ 21 = 40 people/km².
2. A region has a population of 606 people and a land area of 6 km². Calculate its population density.
101 people/km²
Population density = population ÷ area = 606 ÷ 6 = 101 people/km².
3. A region has a population of 510 people and a land area of 17 km². Calculate its population density.
30 people/km²
Population density = population ÷ area = 510 ÷ 17 = 30 people/km².
4. A region has a population of 158 people and a land area of 2 km². Calculate its population density.
79 people/km²
Population density = population ÷ area = 158 ÷ 2 = 79 people/km².
5. A region has a population of 170 people and a land area of 10 km². Calculate its population density.
17 people/km²
Population density = population ÷ area = 170 ÷ 10 = 17 people/km².
6. A region has a population of 2900 people and a land area of 25 km². Calculate its population density.
116 people/km²
Population density = population ÷ area = 2900 ÷ 25 = 116 people/km².
7. A region has a population of 1876 people and a land area of 14 km². Calculate its population density.
134 people/km²
Population density = population ÷ area = 1876 ÷ 14 = 134 people/km².
8. A region has a population of 177 people and a land area of 3 km². Calculate its population density.
59 people/km²
Population density = population ÷ area = 177 ÷ 3 = 59 people/km².
9. A region has a population of 660 people and a land area of 6 km². Calculate its population density.
110 people/km²
Population density = population ÷ area = 660 ÷ 6 = 110 people/km².
10. A region has a population of 30 people and a land area of 3 km². Calculate its population density.
10 people/km²
Population density = population ÷ area = 30 ÷ 3 = 10 people/km².
11. A region has a population of 1350 people and a land area of 18 km². Calculate its population density.
75 people/km²
Population density = population ÷ area = 1350 ÷ 18 = 75 people/km².
12. A region has a population of 507 people and a land area of 13 km². Calculate its population density.
39 people/km²
Population density = population ÷ area = 507 ÷ 13 = 39 people/km².
