Demographic dependency ratios

Answers and reasoning. Review before teaching.

1. In a town, there are 104 young dependants (under 15), 48 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
38
Total dependants = 104 + 48 = 152. Dependency ratio = (152 ÷ 400) × 100 = 38.
2. In a town, there are 328 young dependants (under 15), 176 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
63
Total dependants = 328 + 176 = 504. Dependency ratio = (504 ÷ 800) × 100 = 63.
3. In a town, there are 351 young dependants (under 15), 180 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
59
Total dependants = 351 + 180 = 531. Dependency ratio = (531 ÷ 900) × 100 = 59.
4. In a town, there are 23 young dependants (under 15), 27 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
50
Total dependants = 23 + 27 = 50. Dependency ratio = (50 ÷ 100) × 100 = 50.
5. In a town, there are 26 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).
44
Total dependants = 26 + 18 = 44. Dependency ratio = (44 ÷ 100) × 100 = 44.
6. In a town, there are 48 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).

65
Total dependants = 80 + 50 = 130. Dependency ratio = (130 ÷ 200) × 100 = 65.
9. In a town, there are 96 young dependants (under 15), 60 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
52
Total dependants = 96 + 60 = 156. Dependency ratio = (156 ÷ 300) × 100 = 52.
10. In a town, there are 301 young dependants (under 15), 77 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 = 301 + 77 = 378. Dependency ratio = (378 ÷ 700) × 100 = 54.
11. In a town, there are 84 young dependants (under 15), 120 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
51
Total dependants = 84 + 120 = 204. Dependency ratio = (204 ÷ 400) × 100 = 51.
12. In a town, there are 124 young dependants (under 15), 116 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
