Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 224 young dependants (under 15), 200 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
53
Total dependants = 224 + 200 = 424. Dependency ratio = (424 ÷ 800) × 100 = 53.
2. In a town, there are 234 young dependants (under 15), 171 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
45
Total dependants = 234 + 171 = 405. Dependency ratio = (405 ÷ 900) × 100 = 45.
3. In a town, there are 310 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).
57
Total dependants = 310 + 260 = 570. Dependency ratio = (570 ÷ 1000) × 100 = 57.
4. In a town, there are 23 young dependants (under 15), 20 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 = 23 + 20 = 43. Dependency ratio = (43 ÷ 100) × 100 = 43.
5. In a town, there are 248 young dependants (under 15), 120 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 248 + 120 = 368. Dependency ratio = (368 ÷ 800) × 100 = 46.
6. In a town, there are 270 young dependants (under 15), 110 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
38
Total dependants = 270 + 110 = 380. Dependency ratio = (380 ÷ 1000) × 100 = 38.
7. In a town, there are 22 young dependants (under 15), 23 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
45
Total dependants = 22 + 23 = 45. Dependency ratio = (45 ÷ 100) × 100 = 45.
8. In a town, there are 41 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).
60
Total dependants = 41 + 19 = 60. Dependency ratio = (60 ÷ 100) × 100 = 60.
9. In a town, there are 224 young dependants (under 15), 210 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 = 224 + 210 = 434. Dependency ratio = (434 ÷ 700) × 100 = 62.
10. In a town, there are 231 young dependants (under 15), 77 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
44
Total dependants = 231 + 77 = 308. Dependency ratio = (308 ÷ 700) × 100 = 44.
11. In a town, there are 216 young dependants (under 15), 120 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 216 + 120 = 336. Dependency ratio = (336 ÷ 800) × 100 = 42.
12. In a town, there are 380 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).
64
Total dependants = 380 + 260 = 640. Dependency ratio = (640 ÷ 1000) × 100 = 64.
