Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 243 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).

    41

    Total dependants = 243 + 126 = 369. Dependency ratio = (369 ÷ 900) × 100 = 41.

  2. 2. In a town, there are 108 young dependants (under 15), 108 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    54

    Total dependants = 108 + 108 = 216. Dependency ratio = (216 ÷ 400) × 100 = 54.

  3. 3. In a town, there are 228 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).

    60

    Total dependants = 228 + 132 = 360. Dependency ratio = (360 ÷ 600) × 100 = 60.

  4. 4. In a town, there are 129 young dependants (under 15), 36 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    55

    Total dependants = 129 + 36 = 165. Dependency ratio = (165 ÷ 300) × 100 = 55.

  5. 5. In a town, there are 250 young dependants (under 15), 260 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    51

    Total dependants = 250 + 260 = 510. Dependency ratio = (510 ÷ 1000) × 100 = 51.

  6. 6. In a town, there are 225 young dependants (under 15), 135 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    72

    Total dependants = 225 + 135 = 360. Dependency ratio = (360 ÷ 500) × 100 = 72.

  7. 7. In a town, there are 310 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).

    42

    Total dependants = 310 + 110 = 420. Dependency ratio = (420 ÷ 1000) × 100 = 42.

  8. 8. In a town, there are 279 young dependants (under 15), 153 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    48

    Total dependants = 279 + 153 = 432. Dependency ratio = (432 ÷ 900) × 100 = 48.

  9. 9. In a town, there are 270 young dependants (under 15), 261 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 = 270 + 261 = 531. Dependency ratio = (531 ÷ 900) × 100 = 59.

  10. 10. In a town, there are 370 young dependants (under 15), 90 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 = 370 + 90 = 460. Dependency ratio = (460 ÷ 1000) × 100 = 46.

  11. 11. In a town, there are 380 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).

    59

    Total dependants = 380 + 210 = 590. Dependency ratio = (590 ÷ 1000) × 100 = 59.

  12. 12. In a town, there are 390 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).

    60

    Total dependants = 390 + 210 = 600. Dependency ratio = (600 ÷ 1000) × 100 = 60.
