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.
(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..
(a)
i. The size of the working population (19 - 60 years) is 35% + 25% = 60% of the total population. Therefore, the size of the working population is 200,000 * 60% = 120,000.
ii. The size of the dependent population (0 - 18 years and 60 years and above) is 30% + 10% = 40% of the total population. Therefore, the size of the dependent population is 200,000 * 40% = 80,000.
(b)
If the population (0 - 18 years) is increased by 2%, the new size of the population will be 30% + 2% = 32% of the total population. The number of people in this age group will be 200,000 * 32% = 64,000. If 0.5% of the people aged 61 years and above died, the new percentage of the population in this age group will be 10% - 0.5% = 9.5%. The number of people in this age group will be 200,000 * 9.5% = 19,000. The natural increase in the population is 64,000 + 19,000 - 200,000 = -117,000.
(c)
The age distribution of the population can be described as a young population with a large proportion of the population below the age of 18 years and a smaller proportion of the population aged 60 years and above. This is because 30% of the population is aged 0 - 18 years and only 10% of the population is aged 60 years and above.
