(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..
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% = = 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% = = 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% = 60,000 = 1,200 Percentage population of age group (61 and above) = 10% = 20,000 = 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
