Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 189 young dependants (under 15), 207 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
44
Total dependants = 189 + 207 = 396. Dependency ratio = (396 ÷ 900) × 100 = 44.
2. In a town, there are 40 young dependants (under 15), 23 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
63
Total dependants = 40 + 23 = 63. Dependency ratio = (63 ÷ 100) × 100 = 63.
3. In a town, there are 68 young dependants (under 15), 42 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
55
Total dependants = 68 + 42 = 110. Dependency ratio = (110 ÷ 200) × 100 = 55.
4. 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.
5. In a town, there are 245 young dependants (under 15), 133 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
54
Total dependants = 245 + 133 = 378. Dependency ratio = (378 ÷ 700) × 100 = 54.
6. In a town, there are 192 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).
50
Total dependants = 192 + 108 = 300. Dependency ratio = (300 ÷ 600) × 100 = 50.
7. In a town, there are 66 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).
39
Total dependants = 66 + 51 = 117. Dependency ratio = (117 ÷ 300) × 100 = 39.
8. In a town, there are 125 young dependants (under 15), 100 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
45
Total dependants = 125 + 100 = 225. Dependency ratio = (225 ÷ 500) × 100 = 45.
9. In a town, there are 196 young dependants (under 15), 98 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
42
Total dependants = 196 + 98 = 294. Dependency ratio = (294 ÷ 700) × 100 = 42.
10. In a town, there are 54 young dependants (under 15), 20 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
37
Total dependants = 54 + 20 = 74. Dependency ratio = (74 ÷ 200) × 100 = 37.
11. In a town, there are 125 young dependants (under 15), 60 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 = 125 + 60 = 185. Dependency ratio = (185 ÷ 500) × 100 = 37.
12. In a town, there are 90 young dependants (under 15), 140 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
46
Total dependants = 90 + 140 = 230. Dependency ratio = (230 ÷ 500) × 100 = 46.
