Demographic dependency ratios

Answers and reasoning. Review before teaching.

  1. 1. In a town, there are 78 young dependants (under 15), 16 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    47

    Total dependants = 78 + 16 = 94. Dependency ratio = (94 ÷ 200) × 100 = 47.

  2. 2. In a town, there are 228 young dependants (under 15), 78 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    51

    Total dependants = 228 + 78 = 306. Dependency ratio = (306 ÷ 600) × 100 = 51.

  3. 3. In a town, there are 162 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).

    44

    Total dependants = 162 + 234 = 396. Dependency ratio = (396 ÷ 900) × 100 = 44.

  4. 4. In a town, there are 69 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).

    46

    Total dependants = 69 + 69 = 138. Dependency ratio = (138 ÷ 300) × 100 = 46.

  5. 5. In a town, there are 390 young dependants (under 15), 130 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    52

    Total dependants = 390 + 130 = 520. Dependency ratio = (520 ÷ 1000) × 100 = 52.

  6. 6. In a town, there are 198 young dependants (under 15), 207 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    45

    Total dependants = 198 + 207 = 405. Dependency ratio = (405 ÷ 900) × 100 = 45.

  7. 7. In a town, there are 280 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).

    55

    Total dependants = 280 + 270 = 550. Dependency ratio = (550 ÷ 1000) × 100 = 55.

  8. 8. In a town, there are 92 young dependants (under 15), 88 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    45

    Total dependants = 92 + 88 = 180. Dependency ratio = (180 ÷ 400) × 100 = 45.

  9. 9. In a town, there are 387 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).

    62

    Total dependants = 387 + 171 = 558. Dependency ratio = (558 ÷ 900) × 100 = 62.

  10. 10. 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.

  11. 11. In a town, there are 117 young dependants (under 15), 75 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    64

    Total dependants = 117 + 75 = 192. Dependency ratio = (192 ÷ 300) × 100 = 64.

  12. 12. In a town, there are 378 young dependants (under 15), 189 elderly dependants (65 and over), and 900 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).

    63

    Total dependants = 378 + 189 = 567. Dependency ratio = (567 ÷ 900) × 100 = 63.
