Uncovering the Story Behind Population Pyramids

# data[].attributes.body
• Knowing about population patterns helps countries plan for the future.

• Countries with many young people (like Eritrea) need to focus on schools, jobs, and healthcare for growing families.

• Countries with many older people (like Japan) need more hospitals, retirement homes, and support for seniors.

• Countries like Canada, with a balanced population, must prepare for both helping young families and caring for the aging population.

• Understanding these patterns helps governments make smart decisions about money, healthcare, education, and immigration.

Canada has a balanced population because it is a developed country. It has good healthcare, education, and job opportunities, so people live longer, but birth rates are lower because families choose to have fewer kids.

Dependency Load

Canada has a more balanced population, with 15.1% youth and 20% seniors.

Birth Rate

Canada has a low birth rate of 10 births per 1,000 people, and it is gradually decreasing, showing a stable but aging population.

Life Expectancy

In Canada, lots of people live past 75, so the life expectancy is high, around 84.2 years. Good healthcare and a high standard of living help people live longer.

Dependency load is the percentage (%) of the population that is younger than 15 years old and older than 65 years old, who depend on the working-age population (ages 15–64) to earn money and support them because they are usually too young or too old to work.

Dependency Load

Eritrea has a very young population, with 38.1% of people under 15 and only 4.4% over 65.

Birth Rate

Eritrea has a high birth rate of 26.3 births per 1,000 people, but it is slowly decreasing as families start having fewer children.

Life Expectancy

Eritrea has fewer older people, which shows a lower life expectancy of around 67.5 years.

Dependency Load

Japan has an aging population, with just 11.5% youth and a high 29.7% seniors.

Birth Rate

Japan has a very low birth rate of 6.9 births per 1,000 people, and it is rapidly decreasing, meaning even fewer babies are being born in the future.

Life Expectancy

Japan’s life expectancy is 85.2 years because many people live over 75. Healthy food, exercise, and good healthcare help people live a long time.

# data[].attributes.body
Eritrea has a very young population because it is still developing. Families have more children to help with farming and family work, and there is less access to healthcare, so fewer people live to old age.

# data[].attributes.body
Japan has an aging population because people live very long due to excellent healthcare and a healthy lifestyle. However, birth rates are very low because many young people focus on work and marriage and children are delayed or avoided.
