Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 205 young dependants (under 15), 40 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 = 205 + 40 = 245. Dependency ratio = (245 ÷ 500) × 100 = 49.
2. In a town, there are 35 young dependants (under 15), 22 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
57
Total dependants = 35 + 22 = 57. Dependency ratio = (57 ÷ 100) × 100 = 57.
3. In a town, there are 140 young dependants (under 15), 45 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
37
Total dependants = 140 + 45 = 185. Dependency ratio = (185 ÷ 500) × 100 = 37.
4. In a town, there are 82 young dependants (under 15), 60 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
71
Total dependants = 82 + 60 = 142. Dependency ratio = (142 ÷ 200) × 100 = 71.
5. In a town, there are 260 young dependants (under 15), 200 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 260 + 200 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.
6. In a town, there are 252 young dependants (under 15), 105 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
51
Total dependants = 252 + 105 = 357. Dependency ratio = (357 ÷ 700) × 100 = 51.
7. In a town, there are 44 young dependants (under 15), 8 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
52
Total dependants = 44 + 8 = 52. Dependency ratio = (52 ÷ 100) × 100 = 52.
8. In a town, there are 190 young dependants (under 15), 130 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
64
Total dependants = 190 + 130 = 320. Dependency ratio = (320 ÷ 500) × 100 = 64.
9. In a town, there are 430 young dependants (under 15), 210 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 = 430 + 210 = 640. Dependency ratio = (640 ÷ 1000) × 100 = 64.
10. In a town, there are 44 young dependants (under 15), 26 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
70
Total dependants = 44 + 26 = 70. Dependency ratio = (70 ÷ 100) × 100 = 70.
11. In a town, there are 70 young dependants (under 15), 50 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
60
Total dependants = 70 + 50 = 120. Dependency ratio = (120 ÷ 200) × 100 = 60.
12. In a town, there are 279 young dependants (under 15), 270 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
61
Total dependants = 279 + 270 = 549. Dependency ratio = (549 ÷ 900) × 100 = 61.
