Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 140 young dependants (under 15), 210 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 = 140 + 210 = 350. Dependency ratio = (350 ÷ 700) × 100 = 50.

  2. 2. In a town, there are 124 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).

    58

    Total dependants = 124 + 108 = 232. Dependency ratio = (232 ÷ 400) × 100 = 58.

  3. 3. In a town, there are 175 young dependants (under 15), 110 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 = 175 + 110 = 285. Dependency ratio = (285 ÷ 500) × 100 = 57.

  4. 4. In a town, there are 287 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).

    56

    Total dependants = 287 + 105 = 392. Dependency ratio = (392 ÷ 700) × 100 = 56.

  5. 5. In a town, there are 387 young dependants (under 15), 135 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    58

    Total dependants = 387 + 135 = 522. Dependency ratio = (522 ÷ 900) × 100 = 58.

  6. 6. In a town, there are 72 young dependants (under 15), 48 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    40

    Total dependants = 72 + 48 = 120. Dependency ratio = (120 ÷ 300) × 100 = 40.

  7. 7. In a town, there are 66 young dependants (under 15), 24 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    45

    Total dependants = 66 + 24 = 90. Dependency ratio = (90 ÷ 200) × 100 = 45.

  8. 8. In a town, there are 176 young dependants (under 15), 112 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    72

    Total dependants = 176 + 112 = 288. Dependency ratio = (288 ÷ 400) × 100 = 72.

  9. 9. In a town, there are 90 young dependants (under 15), 42 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    44

    Total dependants = 90 + 42 = 132. Dependency ratio = (132 ÷ 300) × 100 = 44.

  10. 10. In a town, there are 304 young dependants (under 15), 152 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    57

    Total dependants = 304 + 152 = 456. Dependency ratio = (456 ÷ 800) × 100 = 57.

  11. 11. In a town, there are 256 young dependants (under 15), 176 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    54

    Total dependants = 256 + 176 = 432. Dependency ratio = (432 ÷ 800) × 100 = 54.

  12. 12. In a town, there are 155 young dependants (under 15), 45 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    40

    Total dependants = 155 + 45 = 200. Dependency ratio = (200 ÷ 500) × 100 = 40.
