Census
Oluwaseun in the 2020 Census
The 2020 Census recorded 1,298 people with the first name Oluwaseun, which placed it at #10,330 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 Oluwaseun
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Oluwaseun is Black at 97.9%. The next largest groups are White (0.8%) and Two or More Races (0.6%). 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 Oluwaseun 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 Oluwaseun at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Oluwaseun
The name Oluwaseun originates from the Yoruba language spoken in southwestern Nigeria and neighboring regions. It is a compound name formed from the combination of the words "Olu" meaning "Lord" or "Owner," and "aseun" meaning "crown" or "authority." Thus, the name can be interpreted to mean "The Lord owns the crown" or "The Owner of authority."
In Yoruba culture, names often carry deep spiritual and philosophical meanings, reflecting the beliefs and values of the people. The name Oluwaseun is believed to be a recognition of the sovereignty of the Supreme Being, known as Olodumare or Olorun, who is seen as the ultimate source of authority and power.
The earliest recorded instances of the name Oluwaseun can be traced back to the 16th and 17th centuries, during the height of the Oyo Empire, a powerful Yoruba kingdom that dominated the region. Several notable historical figures have borne this name, including:
1. Oluwaseun Oyewole (1540-1608), a renowned warrior and military leader who played a crucial role in the expansion of the Oyo Empire under the reign of Alaafin Abipa.
2. Oluwaseun Akinlolu (1678-1744), a respected scholar and linguist who contributed to the preservation of Yoruba language and culture through his writings and teachings.
3. Oluwaseun Adebayo (1812-1892), a prominent trader and diplomat who facilitated trade relations between the Oyo Empire and neighboring kingdoms.
4. Oluwaseun Ogunlesi (1870-1938), a pioneering educator and advocate for women's rights, who established one of the first schools for girls in southwestern Nigeria.
5. Oluwaseun Ajayi (1904-1988), a renowned historian and author whose seminal work, "Yoruba Warfare in the 19th Century," shed light on the military and political history of the Yoruba people.
While the name Oluwaseun has its roots in traditional Yoruba culture, it has also gained popularity beyond the region, particularly among the Yoruba diaspora communities in other parts of Nigeria, Africa, and the world. Its enduring appeal can be attributed to its rich cultural significance and the reverence for authority and spiritual guidance that it embodies.

FAQ
Oluwaseun: questions and answers
How many people in the U.S. are named Oluwaseun?
Name Census puts the figure at roughly 406 living Americans. We arrive at this by taking every SSA birth registration for Oluwaseun 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 844,223 US residents.
Is Oluwaseun a common name?
We classify Oluwaseun as "Very Rare". It ranks above 82.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 413 babies have been registered with this name.
When was Oluwaseun most popular?
The single biggest year for Oluwaseun was 2007, when 24 babies received the name. The fact that the average living Oluwaseun is about 21 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Oluwaseun in the 2020 Census?
The published 2020 Census first-name tables recorded 1,298 people with the name Oluwaseun, or 0.43 per 100,000 residents. That placed it at #10,330 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 Oluwaseun 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 Oluwaseun?
The 2020 Census sex table shows Oluwaseun on both sides of the split. Of the 1,299 people counted with this name, 791 were male (60.9%) and 508 were female (39.1%). 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 Oluwaseun?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Oluwaseun is Black at 97.9%. The next largest groups are White (0.8%) and Two or More Races (0.6%). 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 Oluwaseun most often in the Census?
Black is the largest reported group for people named Oluwaseun in the 2020 Census, accounting for 97.9% (1,271 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 Oluwaseun in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Oluwaseun a male name?
Yes, 65.9% of people registered as Oluwaseun 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 Oluwaseun still being used today?
Yes. The SSA still recorded Oluwaseun 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 Oluwaseun 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.
