Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 40 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).

    43

    Total dependants = 40 + 46 = 86. Dependency ratio = (86 ÷ 200) × 100 = 43.

  2. 2. In a town, there are 252 young dependants (under 15), 114 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    61

    Total dependants = 252 + 114 = 366. Dependency ratio = (366 ÷ 600) × 100 = 61.

  3. 3. In a town, there are 300 young dependants (under 15), 160 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    46

    Total dependants = 300 + 160 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.

  4. 4. In a town, there are 370 young dependants (under 15), 100 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    47

    Total dependants = 370 + 100 = 470. Dependency ratio = (470 ÷ 1000) × 100 = 47.

  5. 5. In a town, there are 110 young dependants (under 15), 130 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    48

    Total dependants = 110 + 130 = 240. Dependency ratio = (240 ÷ 500) × 100 = 48.

  6. 6. In a town, there are 40 young dependants (under 15), 16 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    28

    Total dependants = 40 + 16 = 56. Dependency ratio = (56 ÷ 200) × 100 = 28.

  7. 7. In a town, there are 48 young dependants (under 15), 34 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    41

    Total dependants = 48 + 34 = 82. Dependency ratio = (82 ÷ 200) × 100 = 41.

  8. 8. In a town, there are 138 young dependants (under 15), 132 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 = 138 + 132 = 270. Dependency ratio = (270 ÷ 600) × 100 = 45.

  9. 9. In a town, there are 440 young dependants (under 15), 170 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    61

    Total dependants = 440 + 170 = 610. Dependency ratio = (610 ÷ 1000) × 100 = 61.

  10. 10. In a town, there are 264 young dependants (under 15), 90 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    59

    Total dependants = 264 + 90 = 354. Dependency ratio = (354 ÷ 600) × 100 = 59.

  11. 11. In a town, there are 78 young dependants (under 15), 81 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    53

    Total dependants = 78 + 81 = 159. Dependency ratio = (159 ÷ 300) × 100 = 53.

  12. 12. In a town, there are 160 young dependants (under 15), 96 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    64

    Total dependants = 160 + 96 = 256. Dependency ratio = (256 ÷ 400) × 100 = 64.
