Quoc in the 2020 Census
The 2020 Census recorded 3,318 people with the first name Quoc, which placed it at #5,234 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Quoc
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Quoc is Asian/Pacific Islander at 98.7%. The next largest groups are White (0.4%) and Two or More Races (0.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Quoc described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Quoc at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Quoc
The name Quoc has its origins in the Vietnamese language. It is a unisex name that translates to "nation" or "country" in English. The name Quoc can be traced back to ancient Vietnam, where it was often used as a symbol of national pride and patriotism.
One of the earliest known references to the name Quoc can be found in the Dai Viet Su Ky Toan Thu, a historical text that chronicles the history of Vietnam from the 3rd century BCE to the 17th century CE. In this text, the name Quoc is mentioned in relation to several prominent figures and events in Vietnamese history.
The name Quoc gained particular significance during the Tran Dynasty (1225-1400 CE), when Vietnam successfully repelled multiple Mongol invasions. During this period, the name Quoc became associated with the concept of national unity and resistance against foreign domination.
One of the most famous historical figures to bear the name Quoc was Quoc Tuan (1238-1300 CE), a prominent Vietnamese general and strategist who played a crucial role in the Vietnamese victory over the Mongols. Quoc Tuan is celebrated as a national hero in Vietnam and is revered for his military prowess and unwavering patriotism.
Another notable figure in Vietnamese history with the name Quoc was Quoc Tri (1530-1604 CE), a renowned poet and scholar of the Le Dynasty. Quoc Tri's writings celebrated Vietnamese culture and traditions, and he is regarded as one of the greatest literary figures of his time.
In more recent history, the name Quoc has been borne by several influential figures in Vietnam. Quoc Dung (1907-1985) was a prominent Vietnamese politician and diplomat who served as the Prime Minister of the Democratic Republic of Vietnam from 1976 to 1981. Quoc Vinh (1920-2000) was a celebrated Vietnamese poet and writer whose works explored themes of national identity and the struggle for independence.
Quoc Huong (1935-2022) was a highly respected Vietnamese novelist and short story writer. His works often dealt with the complexities of Vietnamese society and the challenges faced by ordinary people during times of conflict and upheaval. Quoc Huong's writing was instrumental in preserving and promoting Vietnamese culture and traditions.

FAQ
Quoc: questions and answers
How many people in the U.S. are named Quoc?
Name Census puts the figure at roughly 468 living Americans. We arrive at this by taking every SSA birth registration for Quoc going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 732,381 US residents.
Is Quoc a common name?
We classify Quoc as "Very Rare". It ranks above 83.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 489 babies have been registered with this name.
When was Quoc most popular?
The single biggest year for Quoc was 1982, when 50 babies received the name. The fact that the average living Quoc is about 40 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Quoc in the 2020 Census?
The published 2020 Census first-name tables recorded 3,318 people with the name Quoc, or 1.10 per 100,000 residents. That placed it at #5,234 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Quoc in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Quoc?
In the 2020 Census sex table, Quoc leans strongly male. 3,266 people counted with this name were male (98.4%), compared with 54 female bearers (1.6%). The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Quoc?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Quoc is Asian/Pacific Islander at 98.7%. The next largest groups are White (0.4%) and Two or More Races (0.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Quoc most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Quoc in the 2020 Census, accounting for 98.7% (3,276 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Quoc in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Quoc a male name?
Yes, 100.0% of people registered as Quoc in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Quoc still being used today?
Yes. The SSA still recorded Quoc in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Quoc can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate.
