Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 296 young dependants (under 15), 240 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
67
Total dependants = 296 + 240 = 536. Dependency ratio = (536 ÷ 800) × 100 = 67.
2. In a town, there are 99 young dependants (under 15), 42 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
47
Total dependants = 99 + 42 = 141. Dependency ratio = (141 ÷ 300) × 100 = 47.
3. In a town, there are 210 young dependants (under 15), 60 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
45
Total dependants = 210 + 60 = 270. Dependency ratio = (270 ÷ 600) × 100 = 45.
4. In a town, there are 29 young dependants (under 15), 18 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
47
Total dependants = 29 + 18 = 47. Dependency ratio = (47 ÷ 100) × 100 = 47.
5. In a town, there are 410 young dependants (under 15), 250 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
66
Total dependants = 410 + 250 = 660. Dependency ratio = (660 ÷ 1000) × 100 = 66.
6. In a town, there are 180 young dependants (under 15), 130 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
31
Total dependants = 180 + 130 = 310. Dependency ratio = (310 ÷ 1000) × 100 = 31.
7. In a town, there are 110 young dependants (under 15), 90 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
40
Total dependants = 110 + 90 = 200. Dependency ratio = (200 ÷ 500) × 100 = 40.
8. In a town, there are 220 young dependants (under 15), 90 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
62
Total dependants = 220 + 90 = 310. Dependency ratio = (310 ÷ 500) × 100 = 62.
9. In a town, there are 80 young dependants (under 15), 44 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
31
Total dependants = 80 + 44 = 124. Dependency ratio = (124 ÷ 400) × 100 = 31.
10. In a town, there are 180 young dependants (under 15), 68 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
62
Total dependants = 180 + 68 = 248. Dependency ratio = (248 ÷ 400) × 100 = 62.
11. In a town, there are 147 young dependants (under 15), 154 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
43
Total dependants = 147 + 154 = 301. Dependency ratio = (301 ÷ 700) × 100 = 43.
12. In a town, there are 260 young dependants (under 15), 270 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
53
Total dependants = 260 + 270 = 530. Dependency ratio = (530 ÷ 1000) × 100 = 53.
