Census
Siul in the 2020 Census
The 2020 Census recorded 134 people with the first name Siul, which placed it at #48,062 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.

Ancestry and ethnicity for Siul
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siul is Hispanic at 94.8%. The next largest groups are Asian/Pacific Islander (2.2%) and White (1.5%).

The bar chart below shows how people with the first name Siul 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 Siul at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Siul
The name Siul is believed to have originated from the ancient Sumerian language, one of the earliest known written languages, which was spoken in the southern region of Mesopotamia (modern-day Iraq) around 3000 BCE. The name is thought to be derived from the Sumerian word "si-ul," which means "eternal light" or "radiant one."
In the earliest records, the name Siul was associated with a Sumerian goddess of light and fertility, who was revered for her ability to bring life and abundance to the land. This goddess was often depicted holding a torch or surrounded by rays of light, symbolizing her connection to the sun and the cycle of life.
The name Siul gained prominence during the reign of the Akkadian Empire, which ruled over Mesopotamia from around 2350 BCE to 2150 BCE. One of the earliest recorded individuals bearing this name was Siul-ibni, a high-ranking official and military commander who served under the famous Akkadian king Sargon of Akkad, who ruled around 2334–2279 BCE.
In the later periods of Mesopotamian history, the name Siul was adopted by various Semitic cultures, including the Babylonians and Assyrians. One notable figure was Siul-Bel, a Babylonian astrologer and scholar who lived during the reign of King Nebuchadnezzar II (605–562 BCE). His writings on celestial observations and the interpretation of omens were highly regarded in ancient Mesopotamia.
Another significant historical figure with the name Siul was a Phoenician merchant and explorer who lived around the 6th century BCE. Known as Siul the Voyager, he is credited with establishing trade routes and settlements in the Mediterranean region, contributing to the spread of Phoenician culture and influence.
In the religious texts of Zoroastrianism, an ancient Persian faith, there is a character named Siul-Tora, who is described as a wise sage and teacher. He is believed to have lived in the 6th century BCE and is said to have instructed the prophet Zoroaster in the principles of the religion.
Throughout the centuries, the name Siul has appeared in various forms and spellings across different cultures and languages, such as Siul, Sioul, and Siewl. While its popularity may have waxed and waned over time, the name continues to carry the symbolic meaning of light, radiance, and wisdom, reflecting its ancient roots in the cradle of civilization.

FAQ
Siul: questions and answers
How many people in the U.S. are named Siul?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Siul 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 34,275,434 US residents.
Is Siul a common name?
We classify Siul as "Very Rare". It ranks above 28.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Siul most popular?
The single biggest year for Siul was 2020, when 5 babies received the name. The fact that the average living Siul is about 4 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Siul in the 2020 Census?
The published 2020 Census first-name tables recorded 134 people with the name Siul, or 0.04 per 100,000 residents. That placed it at #48,062 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 Siul 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 Siul?
In the 2020 Census sex table, Siul leans strongly male. 109 people counted with this name were male (83.2%), compared with 22 female bearers (16.8%). 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 Siul?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siul is Hispanic at 94.8%. The next largest groups are Asian/Pacific Islander (2.2%) and White (1.5%). 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 Siul most often in the Census?
Hispanic is the largest reported group for people named Siul in the 2020 Census, accounting for 94.8% (127 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 Siul in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Siul a male name?
Yes, 100.0% of people registered as Siul 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 Siul still being used today?
Yes. The SSA still recorded Siul 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 Siul 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.
