Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 390 young dependants (under 15), 190 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
58
Total dependants = 390 + 190 = 580. Dependency ratio = (580 ÷ 1000) × 100 = 58.
2. In a town, there are 74 young dependants (under 15), 56 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
65
Total dependants = 74 + 56 = 130. Dependency ratio = (130 ÷ 200) × 100 = 65.
3. In a town, there are 120 young dependants (under 15), 24 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
48
Total dependants = 120 + 24 = 144. Dependency ratio = (144 ÷ 300) × 100 = 48.
4. In a town, there are 31 young dependants (under 15), 8 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
39
Total dependants = 31 + 8 = 39. Dependency ratio = (39 ÷ 100) × 100 = 39.
5. In a town, there are 126 young dependants (under 15), 175 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
43
Total dependants = 126 + 175 = 301. Dependency ratio = (301 ÷ 700) × 100 = 43.
6. In a town, there are 124 young dependants (under 15), 120 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
61
Total dependants = 124 + 120 = 244. Dependency ratio = (244 ÷ 400) × 100 = 61.
7. In a town, there are 38 young dependants (under 15), 32 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
35
Total dependants = 38 + 32 = 70. Dependency ratio = (70 ÷ 200) × 100 = 35.
8. In a town, there are 165 young dependants (under 15), 115 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
56
Total dependants = 165 + 115 = 280. Dependency ratio = (280 ÷ 500) × 100 = 56.
9. In a town, there are 315 young dependants (under 15), 133 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
64
Total dependants = 315 + 133 = 448. Dependency ratio = (448 ÷ 700) × 100 = 64.
10. In a town, there are 140 young dependants (under 15), 120 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
52
Total dependants = 140 + 120 = 260. Dependency ratio = (260 ÷ 500) × 100 = 52.
11. In a town, there are 28 young dependants (under 15), 19 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
47
Total dependants = 28 + 19 = 47. Dependency ratio = (47 ÷ 100) × 100 = 47.
12. In a town, there are 410 young dependants (under 15), 260 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
67
Total dependants = 410 + 260 = 670. Dependency ratio = (670 ÷ 1000) × 100 = 67.
