Total number of people living in the country.
How many people live per square kilometer of land.
How long a newborn baby can expect to live on average.
Average number of children born to each woman. About 2.1 is needed to keep population stable.
Half the population is younger and half is older than this age.
Difference between people moving in and out. Positive means more arrivals.
Population Trend
How the total population has changed over the decades. A rising line means the country has been growing, a flat or falling line indicates stagnation or decline.
Population Projection to 2100
Estimated future population based on current trends in birth rates, death rates, and migration. The dashed line shows this is a projection, not actual data.
Birth Rate vs Death Rate
Birth rate (green) vs. death rate (red) per 1,000 people per year. When the birth rate is higher than the death rate, the population grows naturally.
Life Expectancy (Male vs Female)
Average number of years a newborn can expect to live. Blue shows men, red shows women. Women typically live longer in most countries.
Fertility Rate Trend
Total Fertility Rate — the average number of children per woman. A rate of about 2.1 is needed to maintain the population without immigration.
Population Pyramid
Shows the age distribution of the population. Blue bars (left) represent men, red bars (right) represent women. A wide base means a young population, a wide top means an aging population.

Demographic Profile
Guam is located in Micronesia, a part of Oceania, and covers an area of 544 km². With a population of 167,777, the country has a population density of 308.3 inhabitants per square kilometer, which is above the global average of approximately 60 people per km².
The demographic structure of Guam reveals a population in demographic transition. The median age of 34.6 years means that half of the population is younger and half is older than this age. The population is in a transitional phase, with declining birth rates and improving life expectancy gradually shifting the age structure toward an older profile.
Health and Longevity
Life expectancy in Guam stands at 77.2 years overall — 73.4 years for men and 81.4 years for women. This places the country among those with high life expectancy globally, reflecting well-developed healthcare systems and living standards. The infant mortality rate is 0.0 per 1,000 live births, which is considered very low and indicates excellent maternal and infant healthcare.
Fertility and Population Growth
The total fertility rate (TFR) of 2.78 children per woman is above the replacement level of 2.1, contributing to population growth. The population is growing at a rate of 0.76% per year. This moderate growth rate reflects a balance between natural increase and migration patterns.
Migration
Net migration in Guam is -504 people, meaning more people are leaving the country than arriving. Emigration may reflect economic challenges or conflict, and can lead to brain drain as skilled workers seek opportunities elsewhere.
Outlook
Based on current demographic trends, Guam's population dynamics reflect broader patterns seen across Micronesia. The ongoing demographic transition will require careful policy planning to harness the potential of a changing population structure.
