Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 95 young dependants (under 15), 60 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
31
Total dependants = 95 + 60 = 155. Dependency ratio = (155 ÷ 500) × 100 = 31.
2. In a town, there are 280 young dependants (under 15), 200 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
60
Total dependants = 280 + 200 = 480. Dependency ratio = (480 ÷ 800) × 100 = 60.
3. In a town, there are 104 young dependants (under 15), 92 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 104 + 92 = 196. Dependency ratio = (196 ÷ 400) × 100 = 49.
4. In a town, there are 56 young dependants (under 15), 54 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
55
Total dependants = 56 + 54 = 110. Dependency ratio = (110 ÷ 200) × 100 = 55.
5. In a town, there are 351 young dependants (under 15), 99 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
50
Total dependants = 351 + 99 = 450. Dependency ratio = (450 ÷ 900) × 100 = 50.
6. In a town, there are 108 young dependants (under 15), 100 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
52
Total dependants = 108 + 100 = 208. Dependency ratio = (208 ÷ 400) × 100 = 52.
7. In a town, there are 64 young dependants (under 15), 42 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
53
Total dependants = 64 + 42 = 106. Dependency ratio = (106 ÷ 200) × 100 = 53.
8. In a town, there are 88 young dependants (under 15), 96 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 88 + 96 = 184. Dependency ratio = (184 ÷ 400) × 100 = 46.
9. In a town, there are 210 young dependants (under 15), 140 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
35
Total dependants = 210 + 140 = 350. Dependency ratio = (350 ÷ 1000) × 100 = 35.
10. In a town, there are 240 young dependants (under 15), 144 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
48
Total dependants = 240 + 144 = 384. Dependency ratio = (384 ÷ 800) × 100 = 48.
11. In a town, there are 100 young dependants (under 15), 84 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 100 + 84 = 184. Dependency ratio = (184 ÷ 400) × 100 = 46.
12. In a town, there are 174 young dependants (under 15), 60 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
39
Total dependants = 174 + 60 = 234. Dependency ratio = (234 ÷ 600) × 100 = 39.
