Census
Thien in the 2020 Census
The 2020 Census recorded 5,151 people with the first name Thien, which placed it at #3,832 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 Thien
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thien is Asian/Pacific Islander at 97.6%. The next largest groups are White (0.8%) and Two or More Races (0.7%). 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 Thien 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 Thien at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Thien
The name Thien is of Vietnamese origin, derived from the Chinese word "Tian" which means "heaven" or "sky." The name has its roots in ancient Chinese philosophy and culture, where the concept of heaven played a significant role in religious beliefs and cosmological understanding.
Thien first appeared in Vietnamese records during the medieval period, when Vietnam was heavily influenced by Chinese culture and traditions. The name was adopted by Vietnamese families, particularly those of the upper class or scholar-gentry, who appreciated its profound philosophical meaning and connection to the celestial realm.
In ancient Chinese texts, such as the Analects of Confucius and the Tao Te Ching, the concept of "Tian" or "heaven" was often associated with the natural order, divine principles, and the highest moral authority. The name Thien, therefore, carried a sense of reverence and aspiration for virtuous living in harmony with the cosmic order.
One of the earliest recorded instances of the name Thien can be found in the annals of the Ly Dynasty, which ruled Vietnam from 1009 to 1225 AD. Thien Nhan Trung, a renowned Vietnamese Zen Buddhist monk and scholar, lived during this period and was known for his teachings on mindfulness and spiritual enlightenment.
Another notable figure in Vietnamese history who bore the name Thien was Thien Mu Pagoda, a famous Buddhist temple in the city of Hue. Built in the early 17th century, this architectural masterpiece is considered one of the most iconic religious structures in Vietnam and a symbol of the country's rich cultural heritage.
In the realm of literature, Thien Hieu, a Vietnamese poet and scholar from the 18th century, is celebrated for his contributions to the development of the Nom script, an ancient writing system used in Vietnam. His poems and writings explored themes of nature, spirituality, and the human condition, reflecting the philosophical depth associated with the name Thien.
Moving into the modern era, Thien Ngo, a Vietnamese-American author and journalist, has gained recognition for his powerful memoirs and novels that shed light on the experiences of the Vietnamese diaspora and the complexities of cultural identity.
Lastly, Thien Nguyen, a renowned Vietnamese-American chef and restaurateur, has made significant contributions to the culinary world by introducing and popularizing traditional Vietnamese cuisine in the United States, earning him numerous accolades and awards.
These individuals, spanning different eras and fields, exemplify the rich heritage and diverse expressions of the name Thien, which continues to resonate with its celestial origins and philosophical depth in Vietnamese culture.

FAQ
Thien: questions and answers
How many people in the U.S. are named Thien?
Name Census puts the figure at roughly 1,054 living Americans. We arrive at this by taking every SSA birth registration for Thien 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 325,194 US residents.
Is Thien a common name?
We classify Thien as "Rare". It ranks above 90.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,077 babies have been registered with this name.
When was Thien most popular?
The single biggest year for Thien was 1996, when 42 babies received the name. The fact that the average living Thien is about 25 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Thien in the 2020 Census?
The published 2020 Census first-name tables recorded 5,151 people with the name Thien, or 1.71 per 100,000 residents. That placed it at #3,832 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 Thien 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 Thien?
In the 2020 Census sex table, Thien leans strongly male. 4,374 people counted with this name were male (84.9%), compared with 776 female bearers (15.1%). 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 Thien?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thien is Asian/Pacific Islander at 97.6%. The next largest groups are White (0.8%) and Two or More Races (0.7%). 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 Thien most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Thien in the 2020 Census, accounting for 97.6% (5,028 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 Thien in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Thien a male name?
Yes, 97.3% of people registered as Thien 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 Thien still being used today?
Yes. The SSA still recorded Thien 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 Thien 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.
