Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 156 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).
53
Total dependants = 156 + 162 = 318. Dependency ratio = (318 ÷ 600) × 100 = 53.
2. In a town, there are 380 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).
59
Total dependants = 380 + 210 = 590. Dependency ratio = (590 ÷ 1000) × 100 = 59.
3. In a town, there are 114 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).
42
Total dependants = 114 + 138 = 252. Dependency ratio = (252 ÷ 600) × 100 = 42.
4. In a town, there are 99 young dependants (under 15), 27 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 99 + 27 = 126. Dependency ratio = (126 ÷ 300) × 100 = 42.
5. In a town, there are 100 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).
42
Total dependants = 100 + 68 = 168. Dependency ratio = (168 ÷ 400) × 100 = 42.
6. In a town, there are 120 young dependants (under 15), 85 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
41
Total dependants = 120 + 85 = 205. Dependency ratio = (205 ÷ 500) × 100 = 41.
7. In a town, there are 21 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).
38
Total dependants = 21 + 17 = 38. Dependency ratio = (38 ÷ 100) × 100 = 38.
8. In a town, there are 108 young dependants (under 15), 144 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 = 108 + 144 = 252. Dependency ratio = (252 ÷ 600) × 100 = 42.
9. In a town, there are 252 young dependants (under 15), 168 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
70
Total dependants = 252 + 168 = 420. Dependency ratio = (420 ÷ 600) × 100 = 70.
10. In a town, there are 38 young dependants (under 15), 46 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 = 38 + 46 = 84. Dependency ratio = (84 ÷ 200) × 100 = 42.
11. In a town, there are 270 young dependants (under 15), 230 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
50
Total dependants = 270 + 230 = 500. Dependency ratio = (500 ÷ 1000) × 100 = 50.
12. In a town, there are 78 young dependants (under 15), 28 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
53
Total dependants = 78 + 28 = 106. Dependency ratio = (106 ÷ 200) × 100 = 53.
