Chamorro People 2025 | Population Statistics & Facts

Chamorro People 2025

The Chamorro people, also known as Chamoru, represent the indigenous inhabitants of the Mariana Islands, an archipelago in the western Pacific Ocean that has been continuously inhabited for over 3,500 years. The Chamorro people are politically divided between Guam, an unincorporated organized territory of the United States, and the Commonwealth of the Northern Mariana Islands (CNMI), another U.S. commonwealth. Guam, the largest and southernmost island of the Marianas, covers 214 square miles (544 square kilometers) and serves as the cultural heartland for the Chamorro people. As we examine the demographic landscape of Chamorro people in 2025, we discover a resilient indigenous population that has survived centuries of colonization—first by Spain for over 300 years (1668-1898), then by the United States, with a brutal Japanese occupation during World War II (1941-1944)—while maintaining remarkable cultural continuity through language, traditions, and social structures.

The Chamorro people 2025 population statistics reveal a complex picture of indigenous demographic survival and diaspora growth. Based on the 2020 U.S. Census of Guam and United Nations projections, approximately 169,000 people reside in Guam as of mid-year 2025, with Chamorro individuals comprising approximately 37-40% of the island’s multi-ethnic population, representing roughly 63,000 to 68,000 Chamorro people on Guam. An additional estimated 18,000 to 20,000 Chamorros live in the Northern Mariana Islands. Perhaps most significantly, the mainland United States hosts over 150,000 people of Chamorro ancestry, creating a situation where more Chamorros live in the continental U.S. than in their ancestral homeland. This diaspora emerged primarily through military service—Chamorros enlist in the U.S. Armed Forces at the highest per capita rate of any U.S. jurisdiction—and through migration seeking educational and economic opportunities, particularly to California, Washington, Hawaii, Texas, and Nevada.

Interesting Stats & Facts About Chamorro People 2025

The statistics reveal remarkable characteristics about Chamorro people. Guam experienced a 3.5% population decrease between 2010 and 2020, declining from 159,358 to 153,836 residents, reflecting outmigration to the mainland United States and economic challenges. However, the 2025 projection of 168,999 suggests population recovery driven by economic growth, military expansion, and immigration from Freely Associated States. The Chamorro population identified as 63,035 when counting individuals who identified as Chamorro alone or in combination with other groups, but only 50,420 identified as Chamorro alone, representing 32.8% of Guam’s population. This reflects the multi-ethnic character of modern Guam, where Filipinos comprise 29-31%, making them nearly as numerous as Chamorros.

The median age of 31.5 years (2025 projection) positions Guam’s population as relatively young compared to the U.S. national median of over 38 years, though older than many Pacific Island nations. The remarkable literacy rate approaching 99% ranks among the world’s highest, reflecting over a century of American educational investment since U.S. acquisition in 1898. The Catholic population of 87.72% demonstrates the profound impact of Spanish colonization (1668-1898), during which Catholicism became deeply embedded in Chamorro identity. The near-universal urbanization at 98.83% reflects the concentration of settlement in developed areas with infrastructure, though Guam’s “urban” designation includes many village communities that maintain traditional social structures.

Perhaps most striking is the military enlistment rate of 14 per 10,000—the highest of any U.S. jurisdiction—more than double Montana’s rate (the highest among states at ~7 per 10,000). This extraordinary military participation reflects patriotic tradition, economic opportunities through military service, and the strategic importance of Guam as “America’s westernmost territory” and a critical military installation in the Indo-Pacific region. Joint Base Marianas (combining Naval Base Guam and Andersen Air Force Base) and the newly constructed Marine Corps Base Camp Blaz (named after Brigadier General Vicente “Ben” Blaz, the first Chamorro Marine general) employ thousands and anchor the island’s economy.

Chamorro Population Demographics 2025

Data Source: U.S. Census Bureau 2020 Island Areas Census; UN Population Division 2025 Projections

The demographic structure of Chamorro people and Guam residents in 2025 reflects a mature population with substantial working-age cohorts supporting economic activity. The projected total population of 168,999 represents a 9.8% increase from the 2020 census, reversing the 2010-2020 decline. This projected growth stems from multiple factors: continued U.S. military buildup (particularly Marine Corps relocation from Okinawa, Japan), economic recovery from COVID-19 impacts, and immigration from the Freely Associated States (Federated States of Micronesia, Republic of the Marshall Islands, and Republic of Palau) under the Compact of Free Association. The gender distribution remains balanced, with males slightly outnumbering females at 50.9% versus 49.1%, typical of populations with military presence.

The age structure reveals a predominantly working-age population. With 27% under age 18, Guam maintains a substantial youth cohort, though smaller than high-fertility Pacific nations. The working-age population between 18 and 64 constitutes 65.1%, providing a robust labor force for the island’s tourism, military support, construction, and service sectors. The government employment sector, military contractors, and tourism industry absorb much of this workforce. The senior population aged 65 and over at 11.2% indicates moderate aging, reflecting improved healthcare and life expectancy while still far below the 17-20% elderly populations of developed nations.

The median age decrease from 33.7 years (2020) to 31.5 years (2025 projection) appears counterintuitive but reflects immigration of working-age individuals from other Pacific islands and military personnel transfers bringing younger service members and families. The population density increase from 283 to 313 persons per square kilometer results from population growth on the fixed land area of 544 square kilometers. This density concentrates particularly in the northern plateau region where development clusters around military installations, commercial centers in Tamuning and Tumon (the tourism district), and the central villages. Southern Guam remains more rural with mountainous volcanic terrain limiting development but supporting traditional village life where Chamorro culture persists most strongly.

Chamorro Ethnic and Cultural Composition 2025

Data Source: U.S. Census Bureau 2020 Island Areas Census; COFA migration estimates

The ethnic composition of Guam demonstrates extraordinary diversity, with Chamorro people no longer constituting a majority of the population they have inhabited for millennia. When counting individuals who identified as Chamorro alone, the percentage stands at only 32.8%, while Chamorro alone or in combination with other ethnicities reaches 41.0% (63,035 people). This reflects the substantial intermarriage between Chamorros and other groups—particularly Filipinos, other Pacific Islanders, and Americans—creating a large mixed-heritage population that maintains Chamorro cultural identity while acknowledging multiple ethnic backgrounds.

The Filipino population at 30-33% (depending on whether counting alone or in combination) rivals Chamorros numerically, reflecting over a century of migration from the Philippines, which lies only 1,500 miles west of Guam. Filipino migration began during Spanish colonial times, accelerated under U.S. Navy administration (1898-1941), surged during post-WWII reconstruction, and continues today as Filipinos seek employment in healthcare, education, hospitality, and military support services. The Asian population at 32.4% includes not just Filipinos but also smaller numbers of Chinese, Japanese, Korean, and other Asian ethnicities. The White population at 7.2% consists primarily of U.S. military personnel, military family members, federal civilian employees, and business expatriates.

The Other Pacific Islander population at 13.3% represents one of Guam’s most significant demographic shifts. This category primarily includes migrants from the Federated States of Micronesia (Chuukese constitute approximately 7.1% alone), Republic of the Marshall Islands, and Republic of Palau—collectively known as COFA migrants who possess special migration rights to U.S. territories under the Compact of Free Association. From less than 2% in 1980, COFA migrants grew to 4.1% in 1990, 8.3% in 2000, 12.1% in 2010, and an estimated 12-13% in 2020-2025 (approximately 19,000-20,000 people). This rapid growth creates both opportunities and challenges: COFA migrants fill labor shortages in construction, services, and other sectors, but also strain public services including schools, hospitals, and social welfare programs, as the federal government provides limited reimbursement despite their legal admission under federal policy.

The multiracial population at 12.6% reflects Guam’s long history as a crossroads of Pacific cultures and colonial powers. Many Chamorros identify as multiracial, acknowledging Spanish, Filipino, American, or other Pacific Islander ancestry alongside their indigenous heritage. This ethnic mixing, while sometimes seen as diluting indigenous identity, also demonstrates the adaptive resilience of Chamorro culture, which has absorbed external influences while maintaining core values, language elements, and social structures. The pre-colonial caste system, where Chamori referred to the ruling elite, disappeared under Spanish rule, but social hierarchies based on family lineage, Catholic confirmation, and community standing remain important in modern Chamorro society.

Chamorro Language and Cultural Preservation 2025

Data Source: U.S. Census Bureau 2020; Guam Department of Education; UNESCO

The linguistic landscape of Chamorro people reflects the tension between indigenous language preservation and English dominance in education, government, and commerce. While 57.3% of the household population aged 5 and over speaks a language other than English, this statistic includes not just Chamorro but also Philippine languages (primarily Tagalog, Ilocano, and Cebuano), other Pacific Island languages (Chuukese, Marshallese, Palauan), and others. Among non-English speakers, 42.8% speak Philippine languages, indicating that Chamorro represents only a portion of the multilingual reality. The fact that 82.9% of seniors aged 65 and over speak a language other than English suggests stronger native language retention among older generations who grew up when Chamorro was more widely used.

The Chamorro language belongs to the Malayo-Polynesian branch of the Austronesian language family, related to languages spoken in the Philippines, Indonesia, and across the Pacific. However, over 300 years of Spanish colonization profoundly impacted Chamorro, with massive borrowing of Spanish vocabulary, replacement of indigenous counting systems with Spanish numbers, and grammatical influences. English influence accelerated after 1898, and particularly after WWII, to the point where by the 1970s-80s, Chamorro faced potential extinction as younger generations increasingly spoke only English. This crisis prompted preservation efforts, and Guam law now mandates Chamorro language instruction in all public schools from elementary through high school.

Cultural institutions have advocated for standardizing “Chamoru” spelling (rather than the Spanish-influenced “Chamorro”), officially adopted in 2017 Guam Public Law 33-236 and promoted by the Commission on the Chamoru Language and the Teaching of the History and Culture of the Indigenous People of Guam. Despite these efforts, challenges persist: children learn Chamorro in schools but speak English at home and with peers; mixed-ethnicity families often lack Chamorro-speaking parents; and the economic and social advantages of English proficiency create practical disincentives for native language maintenance. Yet a cultural resurgence since the 1990s has brought renewed pride in Chamorro identity, with language classes attracting adult learners, cultural festivals celebrating traditional arts, and social media connecting diaspora Chamorros seeking to reconnect with ancestral language and customs.

The bilingual reality means most Chamorros navigate between English for formal settings and Chamorro for cultural expression, family communication, and identity assertion. Traditional greetings (Håfa Adai – “Hello”), respect terms (sir: señot; ma’am: señora), and cultural concepts (inafa’maolek – harmony; chenchule’ – reciprocity) persist even among primarily English speakers, embedding Chamorro worldview within English communication. The language carries cultural knowledge including traditional navigation, agricultural practices, medicinal plants, and oral histories that risk loss if transmission weakens. Churches conduct some Masses in Chamorro, and traditional chants (chant singers called suruhånu) maintain spiritual and cultural functions. The diaspora Chamorro communities in California, Washington, and elsewhere organize language classes and cultural programs, recognizing that language forms the foundation of distinct indigenous identity in an increasingly globalized world where assimilation pressures threaten cultural survival.

Chamorro Education Statistics 2025

Data Source: Guam Department of Education; U.S. Department of Education; MacroTrends; University of Guam; Guam Community College

The educational profile of Chamorro people and Guam residents reveals high literacy and school access alongside challenges in educational quality and post-secondary attainment. The remarkable literacy rate approaching 99% places Guam among the world’s most literate societies, reflecting over a century of American investment in universal public education since U.S. naval administration began in 1898. The Naval School System established in the early 1900s provided free education to Chamorro children, dramatically increasing literacy from lower levels under Spanish rule. This legacy continues through the Guam Department of Education (GDOE), which operates approximately 40 public schools serving students from pre-kindergarten through 12th grade.

Educational attainment among adults aged 25 and over shows approximately 90% have completed high school or higher education, comparable to U.S. mainland rates. However, the bachelor’s degree attainment rate of 25-30% falls below the U.S. national average of approximately 33-35%, indicating challenges in higher education access and completion. These gaps reflect multiple factors: the limited local higher education options beyond University of Guam (UOG) and Guam Community College (GCC), financial constraints facing families with limited incomes, and the “brain drain” phenomenon where top students leave for mainland universities and often don’t return due to better career opportunities abroad.

University of Guam, established in 1952, enrolls approximately 3,500 students and offers bachelor’s and master’s programs including education, business, nursing, and Pacific Island studies. The university plays a critical role in producing teachers, nurses, and professionals who understand local culture and can serve Guam’s unique needs. Guam Community College, serving approximately 2,500 students, provides vocational training, workforce development, and transfer pathways to four-year institutions. Both institutions face challenges including limited funding, facility needs, and competition from mainland universities attracting Guam’s brightest students.

Educational quality concerns persist despite high literacy rates. Standardized test scores consistently fall below U.S. mainland averages, indicating that while students attend school and learn to read, they often lag in mathematics, science, and advanced literacy skills. Factors include: limited resources and lower per-pupil spending compared to states; challenges of educating a multilingual population (with English language learners from COFA nations); teacher shortages requiring recruitment from the Philippines and mainland U.S.; aging school facilities requiring repair; and socioeconomic factors including poverty affecting approximately 20% of families. The mandatory Chamorro language education represents an additional subject requirement beyond typical U.S. curricula, creating time constraints for core academic subjects while serving the crucial cultural preservation mission.

Catholic and private schools provide alternatives, with institutions like Father Duenas Memorial School, Notre Dame High School, and St. John’s School offering education rooted in Catholic values while maintaining high academic standards. These schools enroll substantial portions of students whose families can afford tuition, contributing to educational stratification. Looking forward, Guam faces the challenge of improving educational outcomes to prepare youth for increasingly competitive global economy while maintaining cultural education that preserves Chamorro identity—a balance requiring sustained investment, innovative pedagogy, and community engagement to ensure that Chamorro people possess both the skills for economic success and the cultural knowledge to maintain indigenous heritage.

Chamorro Employment and Economy 2025

Data Source: U.S. Census Bureau 2020; Guam Department of Labor; Economic data 2020-2024

The employment landscape for Chamorro people and Guam residents reflects an economy heavily dependent on tourism, military spending, and government employment, with limited private sector diversification. The unemployment rate of 10.2% recorded in the 2020 Census reflected COVID-19 pandemic impacts, particularly devastating for tourism-dependent Guam. The tourism sector, which pre-pandemic generated approximately 60% of Guam’s economy, collapsed when international travel ceased, particularly affecting the critical Japanese, South Korean, and Taiwanese visitor markets. Hotels, restaurants, shops, and tour companies laid off thousands, disproportionately impacting Chamorros and Filipinos employed in hospitality. Post-pandemic recovery has been gradual, with 2023-2024 estimates suggesting unemployment declining to 5-6% as tourism rebounds and military construction projects create jobs.

Gender disparities appeared in unemployment, with females experiencing 10.9% unemployment versus 9.6% for males (2020), possibly reflecting greater female employment in hard-hit tourism and retail sectors. The high proportion of full-time, year-round workers at 76.5% among employed persons indicates that when Guam residents secure employment, most work full-time rather than part-time or seasonally. The striking statistic that 56.3% of workers aged 16 and over were born outside Guam demonstrates the territory’s dependence on immigrant labor, particularly Filipinos, COFA migrants, and contractors from Asia filling positions that local residents either cannot fill due to insufficient numbers or choose not to pursue.

Major employment sectors shape economic opportunities. The U.S. military employs thousands directly in Joint Base Marianas (Naval Base Guam and Andersen Air Force Base) and Marine Corps Base Camp Blaz, plus thousands more as contractors in construction, maintenance, security, food services, and professional services. Military spending injects over $2 billion annually into Guam’s economy. The Government of Guam (GovGuam) constitutes another major employer, operating schools, hospitals, public safety, utilities, and administrative agencies. Public sector jobs offer stability, benefits, and pensions attractive to local residents, though government budgets face chronic challenges from limited tax base, unfunded pension liabilities, and occasional cash-flow crises requiring borrowing.

The tourism sector, while recovering, employs tens of thousands in hotels (major properties include Hyatt Regency, Hilton, Westin, Sheraton, and Outrigger), restaurants, retail shops in Tumon tourist district, rental car agencies, tour operations, and entertainment venues. Tourism’s dependence on international visitors creates vulnerability to external shocks—not just pandemics but also economic downturns in source markets, natural disasters (typhoons), and geopolitical tensions. Diversification efforts include developing convention tourism, medical tourism, and positioning Guam as a regional business hub, though progress remains limited.

Income and poverty statistics reveal economic challenges. The median household income of $58,289 (for 2019) appears modest compared to U.S. mainland figures (then approximately $65,000-70,000) and masks Guam’s high cost of living where imported goods command premium prices. Chamorro-headed households earned median income of $61,028, slightly above the territorial average, while Filipino-headed households earned $60,739. However, the poverty rate of 20.2%—meaning one in five residents lives below federal poverty thresholds—indicates substantial economic hardship. Native Hawaiian and Pacific Islander populations face even higher poverty at 28.5%, while Asian households experience lower poverty at 12.3%. Over one-quarter of households with householders aged 25-44 receive SNAP (Supplemental Nutrition Assistance Program) benefits, underscoring food insecurity challenges. Economic pressures drive migration to Hawaii and mainland U.S., where Chamorro families seek higher wages and lower costs of living, though many maintain connections to Guam through remittances, regular visits, and eventual retirement returns.

Chamorro Health and Vital Statistics 2025

Data Source: Guam Department of Public Health and Social Services; U.S. health statistics; Hospital data

The health profile of Chamorro people presents challenges common to Pacific Islander populations, including high rates of non-communicable diseases linked to dietary shifts, lifestyle changes, and genetic predispositions. Life expectancy for Guam residents averages approximately 77-79 years, respectable but below U.S. mainland averages of nearly 79-80 years (pre-pandemic). Pacific Islanders generally experience shorter life expectancy than other ethnic groups due to higher chronic disease burdens, though Chamorro life expectancy has improved substantially from lower levels in earlier generations as healthcare access expanded.

Non-communicable diseases (NCDs) constitute the primary health challenge. Heart disease ranks as the leading cause of death, fueled by high rates of obesity, diabetes, hypertension, and smoking. Diabetes affects disproportionately high percentages of Chamorro and Pacific Islander populations, with prevalence rates substantially exceeding U.S. national averages. Genetic factors may predispose Pacific Islanders to insulin resistance and type 2 diabetes, but environmental factors including dietary shifts from traditional foods (fish, taro, breadfruit) to processed foods high in sugar, salt, and unhealthy fats drive the epidemic. Obesity rates among Chamorros exceed U.S. averages, reflecting reduced physical activity as modern lifestyles replace traditional subsistence activities, cultural values that traditionally equated larger body size with health and prosperity, and economic factors making imported processed foods cheaper and more accessible than fresh produce.

Hypertension (high blood pressure) affects large proportions of adults, increasing risks of stroke, heart attack, and kidney disease. Cancer incidence is rising, with concerns about late-stage diagnosis due to limited screening programs and cultural barriers to seeking preventive care. Specific cancers including colorectal, lung, and breast cancer affect significant numbers, while betel nut chewing—a traditional practice—increases oral cancer risks.
