Where it stands
In 2025 Saudi Arabia has 36,973,555 people, which is 0.45% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 43rd by population, behind Uzbekistan and ahead of Poland.
Since 1960
In 1960 the figure was 2,435,403. Since then the population has grown 15.2×, an average of 4.27% a year upward. It doubled at some point along the way — the year it first reached 4,870,806 was 1977.
The projection keeps rising to the end of the data: 50,528,540 in 2050, 36.7% above 2025. The highest figure on this page is that last one, so no peak has been reached yet.
The ranking in 2050
In 2050 the projected rank is 43rd, the same place as today. Rankings move when other countries grow faster or slower, not only when Saudi Arabia changes.
People and land
Saudi Arabia covers 2,149,690 km² of land, so 2025 density is 17 people per km² — 195th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 1,720 people.
The fertility rate was 2.31 births per woman in 2024, above replacement level but falling in most countries; life expectancy at birth was 79 years (2024); 23.6% of people were under 15 and 3.1% were 65 or older (2025); 85% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.
Its nearest neighbours in the ranking are Uzbekistan just above, with 37.1 million (1× as many), and Poland just below, with 36.4 million (1.01× as many as Poland has).
