Bangladesh and 
Brazil, side by side
In 2026, half of the people in Bangladesh are older than 27. In Brazil, half are older than 36.
UN estimates for mid-2023: Bangladesh 171,466,990 people · Brazil 211,140,729
How to read this: each pyramid stacks a place’s people by age — babies at the bottom, the oldest at the top, men on the left and women on the right. A wide bottom means many children; a wide top means many older people.
Each bar is a share of its own place’s people, so a small country and a large one can be read side by side.

If each place were 100 people
Shrink each population to 100 people and count them. Dots are children under 15, filled squares are people aged 15 to 64, and open squares are people 65 and over. The picture follows the year slider above.

BGD × BRA · families and lifetimes
Children, and how long lives last
If the birth rates of this year held for a whole lifetime, a woman in Bangladesh would have about 2.1 children and a woman in Brazil about 1.6. Life expectancy at birth this year: about 75 years in Bangladesh, about 76 in Brazil.
Children per woman, 2026
Each figure is one child: how many children a woman would have in her lifetime at that year’s rates.
The dashed line at 2.1 is about what it takes for each generation to replace the one before it, leaving migration aside.
How long a newborn can expect to live, 2026
Each block is ten years of life, if the death rates of that year stayed the same all life long.

BGD × BRA · 1950–2100 · how many
How big, and where they are heading
Brazil has about 20% more people than Bangladesh: 214 million against 178 million.
Bangladesh's population is 4.3 times what it was in 1950; Brazil's population is 4.0 times what it was in 1950.
Bangladesh's population is expected to peak in 2071. Meanwhile Brazil's population is expected to peak in 2042. The UN expects Bangladesh to have more people than Brazil from 2052. In 2100: 209 million in Bangladesh, 163 million in Brazil (UN projection, medium).

BGD − BRA · 1950–2100 · every age
Which ages each place has more of
Each column is a year and each row an age, from babies at the bottom to 100 at the top. The shade of a cell shows which place has more of its people at that age — the key beside the picture tells you which shade is Bangladesh and which is Brazil, and the in-between shade means the same. Because it compares shares, a small place and a large one can be compared fairly.

Where they sit among all countries
Every country in the world, every year from 1950 to 2100. The grey cloud shows where most countries are; Bangladesh is drawn in solid blue squares and Brazil in open orange squares, so you can see whether each is ahead of the crowd, behind it or in the middle.

Apparatus
Sources and method
Every figure for Bangladesh and Brazil is the United Nations Population Division's, from World Population Prospects 2024: counted to 2023, and the medium projection for each year after that. Both places are taken from the same release and the same tables, which is what makes them comparable at all.
How the median age and the “100 people” pictures are worked out, and why the pictures of every country leave the regions out: how the figures here are put together.
