Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 58 young dependants (under 15), 54 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    56

    Total dependants = 58 + 54 = 112. Dependency ratio = (112 ÷ 200) × 100 = 56.

  2. 2. In a town, there are 207 young dependants (under 15), 126 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    37

    Total dependants = 207 + 126 = 333. Dependency ratio = (333 ÷ 900) × 100 = 37.

  3. 3. In a town, there are 138 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).

    46

    Total dependants = 138 + 138 = 276. Dependency ratio = (276 ÷ 600) × 100 = 46.

  4. 4. In a town, there are 189 young dependants (under 15), 161 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    50

    Total dependants = 189 + 161 = 350. Dependency ratio = (350 ÷ 700) × 100 = 50.

  5. 5. In a town, there are 84 young dependants (under 15), 26 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 = 84 + 26 = 110. Dependency ratio = (110 ÷ 200) × 100 = 55.

  6. 6. In a town, there are 31 young dependants (under 15), 12 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    43

    Total dependants = 31 + 12 = 43. Dependency ratio = (43 ÷ 100) × 100 = 43.

  7. 7. In a town, there are 216 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).

    64

    Total dependants = 216 + 168 = 384. Dependency ratio = (384 ÷ 600) × 100 = 64.

  8. 8. In a town, there are 176 young dependants (under 15), 232 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    51

    Total dependants = 176 + 232 = 408. Dependency ratio = (408 ÷ 800) × 100 = 51.

  9. 9. In a town, there are 360 young dependants (under 15), 128 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    61

    Total dependants = 360 + 128 = 488. Dependency ratio = (488 ÷ 800) × 100 = 61.

  10. 10. In a town, there are 120 young dependants (under 15), 78 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    66

    Total dependants = 120 + 78 = 198. Dependency ratio = (198 ÷ 300) × 100 = 66.

  11. 11. In a town, there are 96 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).

    35

    Total dependants = 96 + 44 = 140. Dependency ratio = (140 ÷ 400) × 100 = 35.

  12. 12. In a town, there are 270 young dependants (under 15), 300 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    57

    Total dependants = 270 + 300 = 570. Dependency ratio = (570 ÷ 1000) × 100 = 57.
