Guam’s statistics show an island community shaped by young families, multigenerational households, public-sector activity, military construction, tourism, and a linguistically diverse population. The figures below cover different measurement periods: the U.S. Census Bureau’s detailed demographic data describe 2020, income and poverty data refer to 2019, economic data reach 2022, labor figures cover March and December 2025, and visitor measures cover December 2024 or fiscal year 2025.

Population and age
The U.S. Census Bureau’s 2020 Census DHC Summary File for Guam counted 153,836 residents. The population included 78,271 males, or 50.9%, and 75,565 females, or 49.1%. These are census counts rather than current projections.
Guam’s 2020 median age was 33.7 years. Children ages 0 to 17 represented 27.0% of residents, while people ages 65 and over represented 11.2%. Residents ages 85 and over made up 0.8%. Together, these measures describe a population with a substantial share of children alongside a smaller, but meaningful, older population.
The age profile matters for island living because the same community may need schools, family services, employment opportunities, and support for older residents at the same time. The Census Bureau figures do not by themselves measure demand for any particular service, but they establish the demographic context.
Mobility also has a distinctive measurement in the 2020 Census DHC Summary File. Among Guam residents age 5 and over who moved between April 1, 2015, and April 1, 2020, 28.2% reported that a natural disaster was the primary reason for moving. The period is specific: this is not a general measure of all moves or a forecast of future migration.
Households and family life
The 2020 Census DHC Summary File counted 34,804 family households in Guam. Married-couple families accounted for 67.2% of those family households. Separately, 15.8% of all Guam households consisted of one person living alone.
Cohabiting couples represented another visible household pattern. Guam had 3,709 cohabiting couple households in 2020, equal to 8.5% of all households. Female-householder households with no spouse or partner present and children under 18 accounted for 5.4% of Guam households, or 2,343 households.
Multigenerational living was also significant. Multigenerational households accounted for 15.3% of Guam family households in 2020. The measure is based on family households, so it should not be read as a percentage of every household in Guam.
The Census Bureau also reported family and caregiving measures for adults and grandparents. Among women ages 15 and over in Guam households, 67.9% had ever given birth. The median length of marriage for currently married men and women ages 15 and over was 19.1 years.
Among adults ages 30 and over in Guam households, 9.6% were grandparents living with their own grandchildren under 18. Of grandparents living with grandchildren under 18, 36.1% were responsible for their basic needs. Among those grandparents caring for grandchildren, 54.3% had been responsible for them for at least five years. These percentages describe overlapping caregiving populations, not separate portions that should be added together.
Education and language
In 2020, 27.7% of Guam’s population age 3 and over in households was enrolled in school, according to the U.S. Census Bureau 2020 Census DHC Summary File for Guam. Within the enrolled population, 3.7% were in nursery or preschool, 75.6% were in kindergarten through grade 12, and 20.6% were in college, graduate, or professional school.
Educational attainment among residents age 25 and older showed a wide difference between completing high school and completing a four-year degree or higher. In 2020, 86.0% had a high school degree, while 25.3% had a bachelor’s degree or higher. Business was the most common field of study among Guam residents with a bachelor’s degree.
Language use adds another important dimension. In 2020, 57.3% of Guam residents age 5 and over in households spoke a language other than English at home. Among residents who spoke a language other than English at home, 65.9% spoke English very well. Philippine languages accounted for 42.8% of the non-English-at-home group.
These language statistics use different denominators: the first percentage covers residents age 5 and over in households, while the latter two describe the subset who spoke a language other than English at home. They therefore provide context about multilingual life without measuring every language spoken across the island.
Race, ethnicity, and community diversity
The U.S. Census Bureau’s 2020 Island Areas Censuses Detailed Cross-Tabulation Data for Guam reported the following race and ethnicity measures. The categories are Census reporting categories, and the listed percentages refer to Guam’s total population where indicated.
| Census measure | Guam statistic | Measurement period |
|---|---|---|
| Native Hawaiian and Other Pacific Islander alone | 46.0% | 2020 |
| Asian alone | 35.5% | 2020 |
| White alone | 6.8% | 2020 |
| Multiracial population | 10.0% | 2020 |
| Hispanic or Latino, any race | 2.9% | 2020 |
The same Census Bureau cross-tabulation reported different median ages for several groups. The Native Hawaiian and Other Pacific Islander alone population had a median age of 30.1 years. The Asian alone population had a median age of 42.9 years, while the White alone population had a median age of 32.9 years. The Multiracial population had a median age of 21.7 years, and the Hispanic or Latino population had a median age of 28.4 years.
Race and Hispanic or Latino origin are separate Census concepts, so these percentages should not be added as though they were mutually exclusive categories. The data are useful for describing community composition and age differences, but they do not explain the causes of those differences.
Income, poverty, and household support
The Census Bureau’s 2020 Census DHC Summary File for Guam reported 2019 income and poverty measures. Among 145,543 Guam residents in households whose poverty status was determined, 29,408 people, or 20.2%, were below the poverty level. The denominator is the population with poverty status determined, not necessarily every resident counted in the 2020 Census.
Guam’s median household income was $58,289 in 2019. In the same measurement period, 21.8% of Guam households received SNAP benefits. These figures describe household economic conditions before the later labor-market observations listed below and should not be treated as 2025 income estimates.
The poverty and assistance figures also use different units. Poverty is reported for people, while SNAP receipt is reported for households. That distinction matters when comparing the measures or considering how household size and family structure may affect economic experience.
GDP, employment, and public activity
The Bureau of Economic Analysis reported that Guam’s real GDP increased 2.1% in 2021 and 5.1% in 2022. In 2021, private-sector real GDP increased 4.4%, while government-sector real GDP decreased 1.1%.
Several 2022 components also recorded increases. Exports of goods and services increased 150.4%, including a 262.0% increase in exports of services. Private fixed investment increased 14.7%, government spending increased 1.4%, and personal consumption expenditures increased 1.2%. These are reported changes for 2022, not long-term averages or forecasts.
The BEA also reported that total compensation increased from $3,527 million in 2020 to $3,615 million in 2021, a gain of $88 million. The compensation figures are presented in millions of dollars and cover the stated annual periods.
Labor statistics show the scale of several employment groups. The Bureau of Labor Statistics Summary Economic Indicators reported March 2025 private employment of 51,900, construction employment of 12,320, federal government employment of 4,010, Government of Guam employment of 11,890, and total employment of 67,800.
March 2025 private nonsupervisory weekly earnings were $707.16. GovGuam weekly earnings were $1,319.48. A later Bureau of Labor Statistics homepage measure put December 2025 unemployment at 3.1%, with private-sector employment at 52,070, federal government employment at 3,870, Government of Guam employment at 11,750, and total employment at 67,690.
| Labor measure | March 2025 | December 2025 |
|---|---|---|
| Private employment | 51,900 | 52,070 |
| Federal government employment | 4,010 | 3,870 |
| Government of Guam employment | 11,890 | 11,750 |
| Total employment | 67,800 | 67,690 |
| Private-sector nonsupervisory weekly earnings | $707.16 | $729.69 |
| GovGuam weekly earnings | $1,319.48 | $1,401.99 |
The December 2025 figures are from the Bureau of Labor Statistics homepage, while the March 2025 figures are from its Summary Economic Indicators. The table places the supplied observations side by side; it does not establish a trend or adjust for seasonal effects.
Public and defense-linked activity was also reported for fiscal year 2025. Total visitors were 729,124, Department of Defense construction contract awards totaled $956,309,000, and total federal expenditures and obligations were $4,118.7 million. Occupancy tax collected was $30,235,927. These fiscal-year measures are not directly comparable with calendar-year visitor or employment counts.
Tourism and visitor arrivals
The Guam Visitors Bureau’s December 2024 Visitor Arrival Summary counted 67,931 total visitor arrivals. Civilian air arrivals numbered 67,203, civilian sea arrivals numbered 207, and armed forces air arrivals numbered 518.
The same December 2024 summary listed arrivals by origin. Korea accounted for 31,302 arrivals and Japan for 23,825. Other reported totals included 6,767 from the United States and Hawaii, 1,260 from the Philippines, 1,120 from the CNMI, 1,017 from the Federated States of Micronesia, and 792 from Taiwan.
Smaller reported origin counts included 323 arrivals from Palau, 282 from China, 154 from Europe, 91 from Australia, 70 from Singapore, 57 from Hong Kong, 47 from the Republic of the Marshall Islands, 17 from Russia, and 11 from Malaysia.
The December 2024 origin figures are arrival counts for that month, while the 729,124 visitor figure is for fiscal year 2025. Keeping those periods separate is essential: neither number should be presented as the other, and neither alone is a forecast of Guam’s future tourism volume.
