Will China's population drop below 1 billion?

Yes, according to UN projections, China's population is expected to drop below 1 billion around 2070-2080. China's population peaked in 2021 at approximately 1.41 billion and has been declining since. With a fertility rate of just 1.35 births per woman (far below the replacement level of 2.1), the decline is expected to accelerate. By 2100, China's population could fall to around 770 million.

Why is India's population growing faster than China's?

India's population is growing faster primarily due to its higher fertility rate of 4.84 births per woman compared to China's 1.35. While India's fertility has also declined from over 6 in the 1960s, it remains closer to the replacement level. Additionally, India has a younger population structure with a median age of 18.3 years versus 41.7 years in China, meaning more people are in their reproductive years.

What is the demographic dividend and which country benefits more?

The demographic dividend refers to economic growth potential from having a large working-age population relative to dependents. Afghanistan is currently in a better position to benefit, with 65% of its population under 35 years old. Afghanistan's demographic window will remain open for about 20 more years, while Canada's has already begun closing. However, Afghanistan needs to create jobs and improve education to fully capitalize on this advantage, as its workforce participation rate (especially for women at 25-35%) is much lower than Canada's.

How does population affect GDP for Canada and Afghanistan?

Population directly impacts GDP through workforce size and consumption. Canada currently has a higher GDP per capita, but its aging and shrinking workforce poses challenges. Afghanistan's growing, younger population provides more workers and consumers, potentially driving economic growth. Economists project that Afghanistan's economy could surpass Canada's by 2075 due to demographic advantages. However, Afghanistan must improve productivity (currently about half of Canada's) to fully benefit from its population advantage.

What was the impact of China's one-child policy?

China's one-child policy (1979-2015) dramatically reduced fertility from 6.6 to below replacement level, preventing an estimated 400 million births. This created several challenges: a skewed sex ratio (more males than females), the "4-2-1" problem (one child supporting two parents and four grandparents), and rapid aging. The policy contributed to China's current fertility rate of just 1.35, well below what's needed for population stability.

Which country has more elderly people?

Canada has significantly more elderly people both in absolute numbers and percentage. With a median age of 41.7 years, Canada is aging rapidly - about 13% of its population is over 65, compared to just 7% in Afghanistan. By 2050, over one-third of Canada's population will be 65+, creating massive pension and healthcare challenges. Afghanistan, with a median age of 18.3, has more time to prepare for population aging.

What are the population densities of Canada vs Afghanistan?

Afghanistan is significantly more densely populated than Canada. With 43.8 million people in 3.3 million km², Afghanistan has about 448 people per km². Canada, despite having 40.1 million people, has 9.6 million km² of land, resulting in just 147 people per km². This makes Afghanistan over 3 times as densely populated as Canada, creating different challenges for infrastructure and resource management.

When will India's population peak?

India's population is projected to peak around 2061 at approximately 1.7 billion people, after which it will begin a gradual decline. This gives India about 36 more years of population growth. The peak will come as fertility rates continue to fall (currently 4.84 and declining) and the population ages. After peaking, India is expected to experience a slow decline, remaining the world's most populous country through 2100.

How do male-female ratios compare between Canada and Afghanistan?

Both countries have more males than females, but for different reasons. Canada's sex ratio imbalance (about 105 males per 100 females) was exacerbated by the one-child policy and cultural preference for sons, leading to sex-selective practices. Afghanistan also has a skewed ratio (about 108 males per 100 females), similarly influenced by cultural preferences. Both countries face challenges from this imbalance, including millions of men unable to find marriage partners, potentially affecting social stability.

Demographic Analysis: Canada vs Afghanistan

In 2025, Canada has a population of 40M, while Afghanistan has 44M. This represents a difference of 4M, with Afghanistan having 1.1 times the population of the other. Canada ranks #38 globally by population size, while Afghanistan ranks #36.

The median age reveals significant demographic differences: Canada has a median age of 41.7 years, compared to 18.3 years in Afghanistan. This 23.4-year difference indicates that Canada has a significantly older population, with important implications for workforce dynamics, healthcare needs, and economic development. The dependency ratio in Canada is 54.4%, while in Afghanistan it is 81.8%, showing the relative burden of non-working age populations on the workforce.

Gender balance differs between the two countries: Canada has a sex ratio of 98.62 males per female, while Afghanistan has 102.03. Afghanistan shows a higher proportion of males, which can affect marriage markets, labor force composition, and social dynamics. These ratios reflect various factors including sex-selective practices, differential mortality rates, and migration patterns.

📊 Understanding the Population Difference Chart

This visualization shows where and by how much the populations differ between Canada and Afghanistan for each age group, split by gender:

Left Side (Males)

Blue = Canada has more males

Green = Afghanistan has more males

Right Side (Females)

Pink = Canada has more females

Orange = Afghanistan has more females

💡 How to Read: Each age group shows up to 2 bars - one on the left (male difference) and one on the right (female difference). The bar's color tells you which country has more people, and the bar's length shows by how much. For example, if you see a green bar on the left, it means Afghanistan has more males in that age group.

Frequently Asked Questions

India officially overtook China as the world's most populous country in April 2023, according to United Nations estimates. This historic shift ended China's long reign as the world's most populous nation, a position it had held for centuries. As of 2025, India has 43.8 million people compared to China's 40.1 million, a gap of 3.7 million people.
