Algeria and Italy, side by side

Line both places up by age in 2026. In Algeria, half are older than 30; in Italy, half are older than 50.

UN estimates for mid-2023: Algeria 46,164,219 people · Italy 59,499,453

Algeria 48.0 million people Half are older than 30 7 in 100 are 65 or older

Italy 58.9 million people Half are older than 50 26 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.

Algeria

Children, under 15: 29
Aged 15 to 64: 64
Aged 65 and over: 7

Italy

Children, under 15: 11

Aged 65 and over: 26

Children, and how long lives last

Algeria is at about 2.6 children for each woman, at this year's rates; Italy is at about 1.2. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. Babies born this year can expect about 77 years of life in Algeria and about 84 in Italy.

Children per woman, 2026

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

Algeria 2.6

Italy 1.2

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.

Algeria 77 years

Italy 84 years

DZA × ITA · 1950–2100 · how many

How big, and where they are heading

Italy has about 20% more people than Algeria: 58.9 million against 48.0 million.

Since 1950 the two have moved differently: Algeria's population is 5.3 times what it was in 1950, while Italy's population is 1.3 times what it was in 1950.

Looking ahead: Algeria's population is expected to peak in 2090, and Italy's population peaked in 2014. The UN expects Algeria to have more people than Italy from 2041. In 2100: 64.5 million in Algeria, 35.4 million in Italy (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 Algeria and which is Italy, 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; Algeria is drawn in solid blue squares and Italy 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 Algeria and Italy 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.

For how the median age is derived, why “100 people” can read a person high or low, and what the all-country pictures do and do not count, see the method.
