Germany and Tanzania, side by side

Germany in 2026: half the people are older than 47. Tanzania: half are older than 19.

UN estimates for mid-2023: Germany 84,548,231 people · Tanzania 66,617,606

Germany 83.6 million people Half are older than 47 24 in 100 are 65 or older

Tanzania 72.6 million people Half are older than 19 3 in 100 are 65 or older

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.

Compare shapes Compare sizes

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.

Germany

Children, under 15: 14
Aged 15 to 64: 62
Aged 65 and over: 24

Tanzania

Children, under 15: 42
Aged 15 to 64: 55
Aged 65 and over: 3

Children, and how long lives last

If the birth rates of this year held for a whole lifetime, a woman in Germany would have about 1.5 children and a woman in Tanzania about 4.4. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. A baby born in Germany this year can expect to live about 82 years. In Tanzania, about 68.

Children per woman, 2026

Each figure is one child: how many children a woman would have in her lifetime at that year’s rates.

Germany 1.5

Tanzania 4.4

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.

Germany 82 years

Tanzania 68 years

DEU × TZA · 1950–2100 · how many

How big, and where they are heading

Germany has about 20% more people than Tanzania: 83.6 million against 72.6 million.

Set each against its own 1950 self and Germany's population is 1.2 times what it was in 1950, Tanzania's population is 9.5 times what it was in 1950.

Looking ahead: Germany's population peaked in 2024, and Tanzania's population is still growing in 2100. The UN expects Tanzania to have more people than Germany from 2031. In 2100: 70.9 million in Germany, 263 million in Tanzania (UN projection, medium).

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 Germany and which is Tanzania, 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; Germany is drawn in solid blue squares and Tanzania 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 Germany and Tanzania 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.

The working behind the median age, the rounding in the “100 people” pictures and the reason the regions are kept out of the all-country views are all set out in the method.

This is one of 250 pairs with a page. The boxes at the top will take any other two places you want to see side by side.
