Answer:
Sex ratio refers to the ratio of males to females in a population. It is usually expressed as the number of males per 100 females. For example, a sex ratio of 105 would mean there are 105 males for every 100 females in the population.
Studying the sex composition of a population is significant for several reasons. Understanding the sex ratio can provide insights into various social, economic, and health aspects of a population. It can help in planning healthcare services, educational resources, workforce distribution, and understanding gender imbalances in society.
To answer the questions regarding the table provided:
a) To calculate the sex ratio for each country, you need to divide the total female population by the total male population and then multiply by 100 to express it per 100 females.
b) To calculate the Age Dependency Ratio (ADR) for each country, you need to add up the young age population and old age population separately. Then divide the total old age population by the total young age population and multiply by 100 to get the ADR percentage.
c) To determine which country shows the maximum dependency ratio, compare the ADR percentages calculated in part (b) for both countries and identify the one with the higher percentage as the country with the maximum dependency ratio.
