Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 189 young dependants (under 15), 91 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
40
Total dependants = 189 + 91 = 280. Dependency ratio = (280 ÷ 700) × 100 = 40.
2. In a town, there are 324 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).
44
Total dependants = 324 + 72 = 396. Dependency ratio = (396 ÷ 900) × 100 = 44.
3. In a town, there are 196 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).
47
Total dependants = 196 + 133 = 329. Dependency ratio = (329 ÷ 700) × 100 = 47.
4. In a town, there are 168 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).
40
Total dependants = 168 + 72 = 240. Dependency ratio = (240 ÷ 600) × 100 = 40.
5. In a town, there are 195 young dependants (under 15), 50 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 195 + 50 = 245. Dependency ratio = (245 ÷ 500) × 100 = 49.
6. In a town, there are 240 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).
58
Total dependants = 240 + 224 = 464. Dependency ratio = (464 ÷ 800) × 100 = 58.
7. In a town, there are 78 young dependants (under 15), 60 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 78 + 60 = 138. Dependency ratio = (138 ÷ 300) × 100 = 46.
8. In a town, there are 272 young dependants (under 15), 216 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
61
Total dependants = 272 + 216 = 488. Dependency ratio = (488 ÷ 800) × 100 = 61.
9. In a town, there are 352 young dependants (under 15), 216 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
71
Total dependants = 352 + 216 = 568. Dependency ratio = (568 ÷ 800) × 100 = 71.
10. In a town, there are 39 young dependants (under 15), 10 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 39 + 10 = 49. Dependency ratio = (49 ÷ 100) × 100 = 49.
11. In a town, there are 245 young dependants (under 15), 91 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
48
Total dependants = 245 + 91 = 336. Dependency ratio = (336 ÷ 700) × 100 = 48.
12. In a town, there are 87 young dependants (under 15), 39 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 87 + 39 = 126. Dependency ratio = (126 ÷ 300) × 100 = 42.
