Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 369 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).
52
Total dependants = 369 + 99 = 468. Dependency ratio = (468 ÷ 900) × 100 = 52.
2. In a town, there are 288 young dependants (under 15), 72 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
40
Total dependants = 288 + 72 = 360. Dependency ratio = (360 ÷ 900) × 100 = 40.
3. In a town, there are 48 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).
40
Total dependants = 48 + 32 = 80. Dependency ratio = (80 ÷ 200) × 100 = 40.
4. In a town, there are 62 young dependants (under 15), 16 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
39
Total dependants = 62 + 16 = 78. Dependency ratio = (78 ÷ 200) × 100 = 39.
5. In a town, there are 90 young dependants (under 15), 51 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
47
Total dependants = 90 + 51 = 141. Dependency ratio = (141 ÷ 300) × 100 = 47.
6. In a town, there are 44 young dependants (under 15), 12 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
56
Total dependants = 44 + 12 = 56. Dependency ratio = (56 ÷ 100) × 100 = 56.
7. In a town, there are 220 young dependants (under 15), 80 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
60
Total dependants = 220 + 80 = 300. Dependency ratio = (300 ÷ 500) × 100 = 60.
8. In a town, there are 294 young dependants (under 15), 140 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
62
Total dependants = 294 + 140 = 434. Dependency ratio = (434 ÷ 700) × 100 = 62.
9. In a town, there are 304 young dependants (under 15), 192 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
62
Total dependants = 304 + 192 = 496. Dependency ratio = (496 ÷ 800) × 100 = 62.
10. In a town, there are 258 young dependants (under 15), 174 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
72
Total dependants = 258 + 174 = 432. Dependency ratio = (432 ÷ 600) × 100 = 72.
11. In a town, there are 297 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).
54
Total dependants = 297 + 189 = 486. Dependency ratio = (486 ÷ 900) × 100 = 54.
12. In a town, there are 216 young dependants (under 15), 112 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
41
Total dependants = 216 + 112 = 328. Dependency ratio = (328 ÷ 800) × 100 = 41.
