Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 168 young dependants (under 15), 84 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
36
Total dependants = 168 + 84 = 252. Dependency ratio = (252 ÷ 700) × 100 = 36.
2. In a town, there are 129 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).
60
Total dependants = 129 + 51 = 180. Dependency ratio = (180 ÷ 300) × 100 = 60.
3. In a town, there are 238 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).
49
Total dependants = 238 + 105 = 343. Dependency ratio = (343 ÷ 700) × 100 = 49.
4. In a town, there are 66 young dependants (under 15), 18 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 66 + 18 = 84. Dependency ratio = (84 ÷ 200) × 100 = 42.
5. In a town, there are 369 young dependants (under 15), 225 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
66
Total dependants = 369 + 225 = 594. Dependency ratio = (594 ÷ 900) × 100 = 66.
6. In a town, there are 320 young dependants (under 15), 104 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 = 320 + 104 = 424. Dependency ratio = (424 ÷ 800) × 100 = 53.
7. In a town, there are 200 young dependants (under 15), 144 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
43

8. In a town, there are 111 young dependants (under 15), 81 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
64
Total dependants = 111 + 81 = 192. Dependency ratio = (192 ÷ 300) × 100 = 64.
9. In a town, there are 126 young dependants (under 15), 138 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
44
Total dependants = 126 + 138 = 264. Dependency ratio = (264 ÷ 600) × 100 = 44.
10. In a town, there are 31 young dependants (under 15), 17 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
48
Total dependants = 31 + 17 = 48. Dependency ratio = (48 ÷ 100) × 100 = 48.
11. In a town, there are 44 young dependants (under 15), 44 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
44
Total dependants = 44 + 44 = 88. Dependency ratio = (88 ÷ 200) × 100 = 44.
12. In a town, there are 72 young dependants (under 15), 75 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
