Life expectancy: How many more years a person is expected to live, based on their current age. You can estimate this from people aged 75 and up

Birth Rate: The number of babies born each year for every 1,000 people. You can estimate this from the 0-4 age group.

Dependency Load: The part of the population that relies on working population for support, usually those under 15 and over 65 years old.

Kenya has the highest birth rate, with 12.6% of the population aged 0-4, which is much higher than both Canada (4.7% of the population aged 0-4) and Spain (3.7% of the population aged 0-4). Canada’s birth rate is in the middle, while Spain has the lowest. This means Kenya has a younger population overall, while Spain and Canada have lower birth rates.

Spain has the highest life expectancy at 10.3% of the population aged 75+, followed by Canada at 8.9% of the population aged 75+. Kenya has the lowest life expectancy at 0.9% of the population aged 75+. This means people in Spain tend to live the longest, Canada is in the middle, and Kenya has the shortest life span among the three countries.

Kenya has the highest dependency load at 37.2% of the population 14 and under + 65 and older. Spain is in the middle with 19.1% of the population 14 and under + 65 and older. Canada has the lowest dependency load at 17.6% of the population 14 and under + 65 and older. This means Kenya’s working population supports more children, while Spain and Canada support more older adults.

Difference in life expectancy, birth rate, and dependency load exist because of the following factors like:

-Healthcare: Countries with better healthcare(like Canada and Spain) have higher life expectancy.

-Education: In countries with more education, especially for women, the birth rate is usually lower.

-Access to service: Countries with good access to clean water, food, and medical care have lower child death and longer life expectancy.

Looking at life expectancy, birth rate, and dependency load is important because it helps governments and planners understand the needs of a population. Countries with many young people need more schools and opportunities, while those with older people need more healthcare and pension. It also helps prepare for the future workers and those who will need support.
