Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 248 young dependants (under 15), 208 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
57
Total dependants = 248 + 208 = 456. Dependency ratio = (456 ÷ 800) × 100 = 57.
2. In a town, there are 88 young dependants (under 15), 76 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
41
Total dependants = 88 + 76 = 164. Dependency ratio = (164 ÷ 400) × 100 = 41.
3. In a town, there are 252 young dependants (under 15), 252 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
56
Total dependants = 252 + 252 = 504. Dependency ratio = (504 ÷ 900) × 100 = 56.
4. In a town, there are 108 young dependants (under 15), 108 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
36
Total dependants = 108 + 108 = 216. Dependency ratio = (216 ÷ 600) × 100 = 36.
5. In a town, there are 108 young dependants (under 15), 112 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
55
Total dependants = 108 + 112 = 220. Dependency ratio = (220 ÷ 400) × 100 = 55.
6. In a town, there are 215 young dependants (under 15), 110 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
65
Total dependants = 215 + 110 = 325. Dependency ratio = (325 ÷ 500) × 100 = 65.
7. In a town, there are 198 young dependants (under 15), 162 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
60
Total dependants = 198 + 162 = 360. Dependency ratio = (360 ÷ 600) × 100 = 60.
8. In a town, there are 175 young dependants (under 15), 189 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
52
Total dependants = 175 + 189 = 364. Dependency ratio = (364 ÷ 700) × 100 = 52.
9. In a town, there are 145 young dependants (under 15), 65 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 145 + 65 = 210. Dependency ratio = (210 ÷ 500) × 100 = 42.
10. In a town, there are 207 young dependants (under 15), 180 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
43
Total dependants = 207 + 180 = 387. Dependency ratio = (387 ÷ 900) × 100 = 43.
11. In a town, there are 138 young dependants (under 15), 114 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 138 + 114 = 252. Dependency ratio = (252 ÷ 600) × 100 = 42.
12. In a town, there are 33 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).
43
Total dependants = 33 + 10 = 43. Dependency ratio = (43 ÷ 100) × 100 = 43.
