Population density & demographics

Answers and reasoning. Review before teaching.

1. A region has a population of 1425 people and a land area of 19 km². Calculate its population density.
75 people/km²
Population density = population ÷ area = 1425 ÷ 19 = 75 people/km².
2. A region has a population of 710 people and a land area of 5 km². Calculate its population density.
142 people/km²
Population density = population ÷ area = 710 ÷ 5 = 142 people/km².
3. A region has a population of 1020 people and a land area of 17 km². Calculate its population density.
60 people/km²
Population density = population ÷ area = 1020 ÷ 17 = 60 people/km².
4. A region has a population of 2312 people and a land area of 17 km². Calculate its population density.
136 people/km²
Population density = population ÷ area = 2312 ÷ 17 = 136 people/km².
5. A region has a population of 2520 people and a land area of 21 km². Calculate its population density.
120 people/km²
Population density = population ÷ area = 2520 ÷ 21 = 120 people/km².
6. A region has a population of 1027 people and a land area of 13 km². Calculate its population density.
79 people/km²
Population density = population ÷ area = 1027 ÷ 13 = 79 people/km².
7. A region has a population of 2250 people and a land area of 25 km². Calculate its population density.
90 people/km²
Population density = population ÷ area = 2250 ÷ 25 = 90 people/km².
8. A region has a population of 1408 people and a land area of 11 km². Calculate its population density.
128 people/km²
Population density = population ÷ area = 1408 ÷ 11 = 128 people/km².
9. A region has a population of 2160 people and a land area of 15 km². Calculate its population density.
144 people/km²
Population density = population ÷ area = 2160 ÷ 15 = 144 people/km².
10. A region has a population of 1525 people and a land area of 25 km². Calculate its population density.
61 people/km²
Population density = population ÷ area = 1525 ÷ 25 = 61 people/km².
11. A region has a population of 570 people and a land area of 6 km². Calculate its population density.
95 people/km²
Population density = population ÷ area = 570 ÷ 6 = 95 people/km².
12. A region has a population of 1710 people and a land area of 18 km². Calculate its population density.
95 people/km²
Population density = population ÷ area = 1710 ÷ 18 = 95 people/km².
