Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 162 young dependants (under 15), 189 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
39
Total dependants = 162 + 189 = 351. Dependency ratio = (351 ÷ 900) × 100 = 39.
2. In a town, there are 230 young dependants (under 15), 230 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 230 + 230 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.
3. In a town, there are 37 young dependants (under 15), 13 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
50
Total dependants = 37 + 13 = 50. Dependency ratio = (50 ÷ 100) × 100 = 50.
4. In a town, there are 104 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).
50
Total dependants = 104 + 96 = 200. Dependency ratio = (200 ÷ 400) × 100 = 50.
5. In a town, there are 387 young dependants (under 15), 189 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
64
Total dependants = 387 + 189 = 576. Dependency ratio = (576 ÷ 900) × 100 = 64.
6. In a town, there are 208 young dependants (under 15), 184 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 208 + 184 = 392. Dependency ratio = (392 ÷ 800) × 100 = 49.
7. In a town, there are 190 young dependants (under 15), 220 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
41
Total dependants = 190 + 220 = 410. Dependency ratio = (410 ÷ 1000) × 100 = 41.
8. In a town, there are 21 young dependants (under 15), 22 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
43
Total dependants = 21 + 22 = 43. Dependency ratio = (43 ÷ 100) × 100 = 43.
9. In a town, there are 120 young dependants (under 15), 72 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
32
Total dependants = 120 + 72 = 192. Dependency ratio = (192 ÷ 600) × 100 = 32.
10. In a town, there are 33 young dependants (under 15), 25 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
58
Total dependants = 33 + 25 = 58. Dependency ratio = (58 ÷ 100) × 100 = 58.
11. In a town, there are 120 young dependants (under 15), 88 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 = 120 + 88 = 208. Dependency ratio = (208 ÷ 400) × 100 = 52.
12. In a town, there are 160 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).
56
Total dependants = 160 + 120 = 280. Dependency ratio = (280 ÷ 500) × 100 = 56.
