Analysis:

Ghana has the highest dependency load at 39.7%, mainly because it has many young people (35.9% under 14) and fewer elderly (3.8% over 65).

Canada has the lowest dependency load at 35.1%, with a moderate number of young people (15.1%) but a larger elderly population (20%).

Italy's dependency load is 36.6%, with fewer young people (12.2%) but a high percentage of older people (24.4%), showing it has more challenges with an aging population.

Analysis:

Ghana has the highest birth rate, with 12.4% of its population being children aged 0 to 4. This means the largest portion of its population is babies.

Canada’s total percentage of young children is lower, at 4.7%, indicating fewer babies compared to Ghana.

Italy has the lowest birth rate with 3.5% of its people being under 4, reflecting a smaller proportion of young children and an aging population.

Analysis:

Italy has the highest life expectancy, with a percentage of people aged 75 and older at 12.7%, showing it has a large elderly population.

Canada follows with 8.9%, showing a significant but smaller proportion of seniors.

Ghana has the lowest life expectancy, having only 1.2% of people 75 and older, reflecting a much younger population.

Canada has a balanced population due to its moderate birth rates which are influenced by lifestyle choices, and an aging population due to the effects of the baby boom and increase in life expectancy.

Whereas Ghana has a younger population due to higher birth rates, leading to a higher dependency load. Additionally, due to limited healthcare Ghana has a shorter life expectancy.

Contrary to Ghana, Italy has an older population with very low birth rates, creating a high dependency load and challenges with an aging population as a result of the country’s long life expectancy, which has developed because of its advanced healthcare, nutrition and living standards.

It is important to look at this information, and to understand the differences in life expectancies and birth rates because it helps countries plan for both the short-term needs of their people, like healthcare, education, and jobs, and the long-term challenges, like an aging population or fewer people in the workforce. For example, countries with low birth rates may need to care for an aging population, while countries with high birth rates need to focus on education and jobs for younger people. This information helps governments make better decisions, so that countries can thrive both now and in the future.

1. Dependency Load: Dependency load refers to the population of people who are not in the workforce, like children aged 0 to 14, and elderly people 65 and older, and rely on others for support. They depend on the working class, usually people from ages 15 to 64, for financial aid.

2. Birth rate: Birth rate is the number of births in a population over a specific period of time. It helps show how fast a population is growing.

3. Life expectancy: Life expectancy is the average number of years a person is expected to live, it can vary depending on factors such as healthcare, lifestyle, and geography.
