The table below shows the percentage age distribution of population of country Y in 2010. The population was 200,000. Use the information in the table to answer the questions that follow.
(a) Calculate the size of the
i. working population
ii. dependent population
(b) If the population (0 -18) years is increased by 2% and 0.5% of the ages 61 years and above have died, what is the natural increase in the population.
(c) How will you describe the age distribution of the population? Give a reason for your answer..
| Age group (year) | 0 - 18 | 19 - 40 | 41 - 60 | 60 and above |

Correct Answer: Option
Explanation:
(a)i. The size of the working population is;
= population of age group (19 - 40) + population of age group (41 - 60)
= 35% + 25% = 60%
= \(\frac{60}{100} \times \frac{200,000}{1}\) = 120,000
OR
35% of 200,000 = 70,000
25% of 200,000 = 50,000
70,000 + 50,000 = 120,000
(ii) The size of the dependent population = population of age group (0 - 18) + age group (61 and above)
= 30% + 10% = 40%
= \(\frac{40}{100} \times \frac{200,000}{1}\) = 80,000
OR
30% of 200,000 = 60,000
10% of 200, 000 = 20,000
60,000 + 20,000 = 80,000
(b) Percentage of population of age group (0 - 18) = 30%
\(\frac{30}{100} \times \frac{200,000}{1}\) = 60,000
\(\frac{2}{100} \times \frac{60,000}{1}\) = 1,200
Percentage population of age group (61 and above) = 10%
\(\frac{10}{100} \times \frac{200,000}{1}\) = 20,000
\(\frac{0.5}{100} \times \frac{20,000}{1}\) = 100
Natural increase in the population
= Births - Deaths
= 1,200 - 100 = 1,100
(c) The population is growing / a youthful one. This is because the population of the youth is more tha of the aged
(a)i. The size of the working population is;
= population of age group (19 - 40) + population of age group (41 - 60)
= 35% + 25% = 60%
= \(\frac{60}{100} \times \frac{200,000}{1}\) = 120,000
OR
35% of 200,000 = 70,000
25% of 200,000 = 50,000
70,000 + 50,000 = 120,000
(ii) The size of the dependent population = population of age group (0 - 18) + age group (61 and above)
= 30% + 10% = 40%
= \(\frac{40}{100} \times \frac{200,000}{1}\) = 80,000
OR
30% of 200,000 = 60,000
10% of 200, 000 = 20,000
60,000 + 20,000 = 80,000
(b) Percentage of population of age group (0 - 18) = 30%
\(\frac{30}{100} \times \frac{200,000}{1}\) = 60,000
\(\frac{2}{100} \times \frac{60,000}{1}\) = 1,200
Percentage population of age group (61 and above) = 10%
\(\frac{10}{100} \times \frac{200,000}{1}\) = 20,000
\(\frac{0.5}{100} \times \frac{20,000}{1}\) = 100
Natural increase in the population
= Births - Deaths
= 1,200 - 100 = 1,100
(c) The population is growing / a youthful one. This is because the population of the youth is more tha of the aged
