OCT. 20, 2022 — Today, the U.S. Census Bureau released a demographic profile of Guam from the 2020 Island Areas Censuses. The demographic profile provides basic demographic, social, economic and housing characteristics for Guam and lower levels of geography. 

In 2020, Guam’s population was 153,836. The profile released today provides demographic characteristics about the population, including information on racial and ethnic composition.

• The Native Hawaiian and Other Pacific Islander population was the largest race group, with 70,809 people identifying as Native Hawaiian and Other Pacific Islander alone. Overall, 83,368 people reported Native Hawaiian and Other Pacific Islander alone or in combination with another race group, such as Asian.
  • The Chamorro population was the largest detailed Native Hawaiian and Other Pacific Islander group.
    • In 2020, 50,420 people identified as Chamorro alone with no additional detailed Native Hawaiian and Other Pacific Islander group or race group.
    • In 2020, 63,035 people identified as Chamorro alone or in any combination with another detailed Native Hawaiian and Other Pacific Islander group or race group, such as Pohnpeian or Asian.
• The Asian population was the second-largest race group, with 54,586 people identifying as Asian alone. Overall, 66,194 people reported Asian alone or in combination with another race group, such as Native Hawaiian and Other Pacific Islander.
  • The Filipino population was the largest detailed Asian group.
  • In 2020, 44,793 people identified as Filipino alone with no additional detailed Asian group or race group.
  • In 2020, 54,242 people identified as Filipino alone or in any combination with another detailed Asian group or race group, such as Japanese or Native Hawaiian and Other Pacific Islander.
• The next largest race groups were White alone, Black or African American alone, Some Other Race alone, and American Indian and Alaska Native alone.
• The Multiracial population (also referred to as the Two or More Races population) was 15,441.
• The Hispanic or Latino (of any race) population was 4,522.
• The Mexican population was the largest detailed Hispanic or Latino group, with 1,740 people identifying as Mexican.

It is important to note that comparisons between the 2020 and 2010 race and ethnicity data should be made with caution. This decade, the Census Bureau improved the Hispanic origin and race questions and how it codes responses. The differences in the overall racial distributions relative to the 2010 data are largely because of these questionnaire and data processing improvements as well as some demographic changes. More information is available in the subject definitions for race and Hispanic origin in the technical documentation.

Among the social characteristics, the 2020 Island Areas Censuses collected information about school enrollment, educational attainment, place of birth, and language spoken at home. 

The 2020 Island Areas Censuses provides a variety of economic characteristics for Guam, including statistics on income and poverty. Income questions on the census asked about income for the prior calendar year.

• Median household income in Guam was $58,289 in 2019. 
• The percentage of families in poverty in Guam was 16.8% in 2019.  

The Census Bureau recommends against comparing household income and poverty data between 2010 and 2020 for Guam because of differences in the universes. The 2010 Island Area Census for Guam included all households in Guam while the 2020 Island Area Census excluded military households.

Among the housing characteristics, the 2020 Island Areas Censuses provides information on homeownership and household size.

• The homeownership rate in Guam was 52.0% in 2020, up slightly from 50.3% in 2010.
• The average household size in Guam decreased from 3.83 in 2010 to 3.44 in 2020.

The 2020 Island Areas Censuses also collected information about computer and internet use, including type of computer devices, internet subscription status, and type of internet service.

• Among all households in Guam, 95.0% had a least one type of computer and 85.9% had a broadband internet subscription.

More information about computer and internet use is available in the “America Counts: Stories Behind the Numbers” article 2020 Island Areas Censuses: Computer and Internet Use.

Characteristics of military housing units in Guam were not collected in 2020. As a result, data tables for these detailed characteristics do not include the population living on military installations. Direct comparisons between the 2010 and 2020 computer and internet use responses for Guam are not recommended because of these differences.

While the 2020 Island Areas Censuses operation was successful, the COVID-19 pandemic impacted the quality of the detailed social, economic and housing characteristic data for American Samoa, Guam and the U.S. Virgin Islands. To ensure the Census Bureau's high data quality standards are met, adjustments were made to data products reporting population and housing characteristics.

Data users should consider the following when using Guam's data products:

• Data tables reporting social and economic characteristics do not include the group quarters population in the table universe. As a result, impacted 2020 data tables should not be compared to 2010 and other past census data tables reporting the same characteristics. The Census Bureau advises data users to verify table universes are the same before comparing data across census years.
• Cells in data tables will display the letter "N" when those data are not statistically reliable.
• The Census Bureau advises that data users consider high allocation rates while using the 2020 Census of Guam's available characteristics data.

Additional guidance for data users using the Island Area characteristics data is available in the Guidance on Using Data from the 2020 Island Areas Censuses fact sheet.

The 2020 Island Areas Censuses provide a wide range of demographic, social, economic and housing information to meet the U.S. Island Areas’ data needs. Other surveys, such as the American Community Survey (ACS), are not conducted in the Island Areas. Therefore, the Census Bureau used a long-form census questionnaire similar to the ACS questionnaire used in the 50 states, the District of Columbia and Puerto Rico. 

The Census Bureau previously released population and housing counts for Guam from the 2020 Island Areas Censuses and plans to release additional demographic, social, economic and housing characteristics in July 2023.
