Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 81 young dependants (under 15), 81 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
54
Total dependants = 81 + 81 = 162. Dependency ratio = (162 ÷ 300) × 100 = 54.
2. In a town, there are 180 young dependants (under 15), 125 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
61
Total dependants = 180 + 125 = 305. Dependency ratio = (305 ÷ 500) × 100 = 61.
3. In a town, there are 184 young dependants (under 15), 224 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
51
Total dependants = 184 + 224 = 408. Dependency ratio = (408 ÷ 800) × 100 = 51.
4. In a town, there are 48 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).
51
Total dependants = 48 + 54 = 102. Dependency ratio = (102 ÷ 200) × 100 = 51.
5. In a town, there are 222 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).
47
Total dependants = 222 + 60 = 282. Dependency ratio = (282 ÷ 600) × 100 = 47.
6. In a town, there are 324 young dependants (under 15), 243 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
63
Total dependants = 324 + 243 = 567. Dependency ratio = (567 ÷ 900) × 100 = 63.
7. In a town, there are 19 young dependants (under 15), 17 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
36
Total dependants = 19 + 17 = 36. Dependency ratio = (36 ÷ 100) × 100 = 36.
8. In a town, there are 84 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).
43
Total dependants = 84 + 88 = 172. Dependency ratio = (172 ÷ 400) × 100 = 43.
9. In a town, there are 100 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).
50
Total dependants = 100 + 100 = 200. Dependency ratio = (200 ÷ 400) × 100 = 50.
10. In a town, there are 240 young dependants (under 15), 136 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
47
Total dependants = 240 + 136 = 376. Dependency ratio = (376 ÷ 800) × 100 = 47.
11. In a town, there are 52 young dependants (under 15), 18 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 = 52 + 18 = 70. Dependency ratio = (70 ÷ 200) × 100 = 35.
12. In a town, there are 90 young dependants (under 15), 34 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
62
Total dependants = 90 + 34 = 124. Dependency ratio = (124 ÷ 200) × 100 = 62.
