Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 180 young dependants (under 15), 171 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    39

    Total dependants = 180 + 171 = 351. Dependency ratio = (351 ÷ 900) × 100 = 39.

  2. 2. In a town, there are 160 young dependants (under 15), 70 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    46

    Total dependants = 160 + 70 = 230. Dependency ratio = (230 ÷ 500) × 100 = 46.

  3. 3. In a town, there are 150 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).

    47

    Total dependants = 150 + 132 = 282. Dependency ratio = (282 ÷ 600) × 100 = 47.

  4. 4. In a town, there are 180 young dependants (under 15), 168 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    58

    Total dependants = 180 + 168 = 348. Dependency ratio = (348 ÷ 600) × 100 = 58.

  5. 5. In a town, there are 222 young dependants (under 15), 66 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    48

    Total dependants = 222 + 66 = 288. Dependency ratio = (288 ÷ 600) × 100 = 48.

  6. 6. In a town, there are 84 young dependants (under 15), 52 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    34

    Total dependants = 84 + 52 = 136. Dependency ratio = (136 ÷ 400) × 100 = 34.

  7. 7. In a town, there are 52 young dependants (under 15), 48 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    50

    Total dependants = 52 + 48 = 100. Dependency ratio = (100 ÷ 200) × 100 = 50.

  8. 8. In a town, there are 168 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).

    32

    Total dependants = 168 + 56 = 224. Dependency ratio = (224 ÷ 700) × 100 = 32.

  9. 9. In a town, there are 80 young dependants (under 15), 68 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    37

    Total dependants = 80 + 68 = 148. Dependency ratio = (148 ÷ 400) × 100 = 37.

  10. 10. In a town, there are 198 young dependants (under 15), 234 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 = 198 + 234 = 432. Dependency ratio = (432 ÷ 900) × 100 = 48.

  11. 11. In a town, there are 66 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).

    52

    Total dependants = 66 + 90 = 156. Dependency ratio = (156 ÷ 300) × 100 = 52.

  12. 12. In a town, there are 115 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).

    34

    Total dependants = 115 + 55 = 170. Dependency ratio = (170 ÷ 500) × 100 = 34.
