Sex ratio: — Number of males per 100 females in the population.

The trajectory

Population peaked in 2002

Total population from 1950 to 2100 (projections beyond 2024)

Since the 2002 peak, the population has declined by 19.3%.

Population structure

How is the population split by gender?

Male and female population with sex ratio trend

No population by gender data available.

The sex ratio of 101.7 males per 100 females is close to the global average.

Density & aging

Density

People per square kilometre

Median age

Age where half the population is younger

Population density of 230 people per km² is moderate by global standards. The median age is projected to rise by 7 years by 2050, from 28.7 to 35.6.

Rate of change

How fast is the population changing?

Annual percentage change in population size

Growth peaked at 3.88% in 1981.

The bottom line

American Samoa passed its population peak 23 years ago in 2002, and has since declined by 19.3%. The population is aging rapidly—median age will rise from 29 to 36 by 2050. UN projections show a decline to 32.3K by 2100.
