Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 29 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).

    46

    Total dependants = 29 + 17 = 46. Dependency ratio = (46 ÷ 100) × 100 = 46.

  2. 2. In a town, there are 100 young dependants (under 15), 145 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    49

    Total dependants = 100 + 145 = 245. Dependency ratio = (245 ÷ 500) × 100 = 49.

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

    54

    Total dependants = 270 + 270 = 540. Dependency ratio = (540 ÷ 1000) × 100 = 54.

  4. 4. In a town, there are 168 young dependants (under 15), 105 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    39

    Total dependants = 168 + 105 = 273. Dependency ratio = (273 ÷ 700) × 100 = 39.

  5. 5. In a town, there are 190 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).

    64

    Total dependants = 190 + 130 = 320. Dependency ratio = (320 ÷ 500) × 100 = 64.

  6. 6. In a town, there are 126 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).

    39

    Total dependants = 126 + 108 = 234. Dependency ratio = (234 ÷ 600) × 100 = 39.

  7. 7. In a town, there are 301 young dependants (under 15), 175 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    68

    Total dependants = 301 + 175 = 476. Dependency ratio = (476 ÷ 700) × 100 = 68.

  8. 8. In a town, there are 108 young dependants (under 15), 69 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    59

    Total dependants = 108 + 69 = 177. Dependency ratio = (177 ÷ 300) × 100 = 59.

  9. 9. In a town, there are 170 young dependants (under 15), 105 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    55

    Total dependants = 170 + 105 = 275. Dependency ratio = (275 ÷ 500) × 100 = 55.

  10. 10. In a town, there are 230 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).

    46

    Total dependants = 230 + 230 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.

  11. 11. In a town, there are 333 young dependants (under 15), 243 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    64

    Total dependants = 333 + 243 = 576. Dependency ratio = (576 ÷ 900) × 100 = 64.

  12. 12. In a town, there are 135 young dependants (under 15), 150 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    57

    Total dependants = 135 + 150 = 285. Dependency ratio = (285 ÷ 500) × 100 = 57.
