Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 264 young dependants (under 15), 120 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 = 264 + 120 = 384. Dependency ratio = (384 ÷ 600) × 100 = 64.

  2. 2. In a town, there are 224 young dependants (under 15), 63 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    41

    Total dependants = 224 + 63 = 287. Dependency ratio = (287 ÷ 700) × 100 = 41.

  3. 3. In a town, there are 215 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).

    64

    Total dependants = 215 + 105 = 320. Dependency ratio = (320 ÷ 500) × 100 = 64.

  4. 4. In a town, there are 195 young dependants (under 15), 125 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 = 195 + 125 = 320. Dependency ratio = (320 ÷ 500) × 100 = 64.

  5. 5. In a town, there are 215 young dependants (under 15), 55 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    54

    Total dependants = 215 + 55 = 270. Dependency ratio = (270 ÷ 500) × 100 = 54.

  6. 6. In a town, there are 133 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).

    30

    Total dependants = 133 + 77 = 210. Dependency ratio = (210 ÷ 700) × 100 = 30.

  7. 7. In a town, there are 72 young dependants (under 15), 63 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    45

    Total dependants = 72 + 63 = 135. Dependency ratio = (135 ÷ 300) × 100 = 45.

  8. 8. In a town, there are 120 young dependants (under 15), 120 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 = 120 + 120 = 240. Dependency ratio = (240 ÷ 500) × 100 = 48.

  9. 9. In a town, there are 111 young dependants (under 15), 90 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    67

    Total dependants = 111 + 90 = 201. Dependency ratio = (201 ÷ 300) × 100 = 67.

  10. 10. In a town, there are 250 young dependants (under 15), 210 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 = 250 + 210 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.

  11. 11. In a town, there are 320 young dependants (under 15), 110 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    43

    Total dependants = 320 + 110 = 430. Dependency ratio = (430 ÷ 1000) × 100 = 43.

  12. 12. In a town, there are 280 young dependants (under 15), 56 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    48

    Total dependants = 280 + 56 = 336. Dependency ratio = (336 ÷ 700) × 100 = 48.
