Census
Jaysun in the 2020 Census
The 2020 Census recorded 187 people with the first name Jaysun, which placed it at #40,012 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 Jaysun
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jaysun is White at 36.9%. The next largest groups are Hispanic (24.1%) and Black (23.0%). 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 Jaysun 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 Jaysun at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Jaysun
The name Jaysun is a modern variation of the ancient Greek name Jason, which is derived from the verb "iaomai," meaning "to heal." It is believed to have originated in the 6th century BC and was popularized by the legendary hero Jason, the leader of the Argonauts in Greek mythology who embarked on a quest to retrieve the Golden Fleece.
One of the earliest recorded references to the name Jason can be found in the epic poem "Argonautica" by Apollonius of Rhodes, written in the 3rd century BC. This work chronicles the adventures of Jason and his crew as they sail across the Black Sea in search of the Golden Fleece. The name Jason also appears in various other ancient Greek texts, including the works of Pindar, Euripides, and Apollodorus.
Throughout history, several notable figures have borne the name Jason. One of the most famous was Jason of Pherae, a 4th century BC ruler of Thessaly, who is remembered for his military conquests and political ambitions. Another prominent Jason was Jason of Cyrene, a 2nd century BC Jewish historian and author of a work known as the "Antiquities of the Jews."
In the medieval period, the name Jason was less common, but it did appear in some literary works, such as the 14th century Italian poem "Il Teseida" by Boccaccio. During the Renaissance, the name experienced a resurgence in popularity, particularly among humanists and scholars who drew inspiration from classical Greek and Roman culture.
One notable Renaissance figure named Jason was Jason de Mayno (1435-1519), an Italian jurist and legal scholar who made significant contributions to the development of canon law. Another was Jason Denores (1530-1590), a French Protestant reformer and theologian who played a prominent role in the Huguenot movement.
In more recent times, the name Jason has continued to be used, though less frequently than its variant spellings like Jaysun. Some notable individuals named Jason include Jason Bourne, the fictional protagonist of Robert Ludlum's thriller novels, Jason Statham, the English actor known for his roles in action films, and Jason Momoa, the American actor known for his roles in popular TV shows and movies.

FAQ
Jaysun: questions and answers
How many people in the U.S. are named Jaysun?
Name Census puts the figure at roughly 196 living Americans. We arrive at this by taking every SSA birth registration for Jaysun 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 1,748,747 US residents.
Is Jaysun a common name?
We classify Jaysun as "Very Rare". It ranks above 74% of all first names in the SSA dataset by living bearers. Across the full history of the data, 199 babies have been registered with this name.
When was Jaysun most popular?
The single biggest year for Jaysun was 2002, when 12 babies received the name. The fact that the average living Jaysun is about 20 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Jaysun in the 2020 Census?
The published 2020 Census first-name tables recorded 187 people with the name Jaysun, or 0.06 per 100,000 residents. That placed it at #40,012 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 Jaysun 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 Jaysun?
In the 2020 Census sex table, Jaysun appears almost entirely male. Of the 181 people counted with this name, 100.0% were male and only a very small share were female. 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 Jaysun?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jaysun is White at 36.9%. The next largest groups are Hispanic (24.1%) and Black (23.0%). 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 Jaysun most often in the Census?
White is the largest reported group for people named Jaysun in the 2020 Census, accounting for 36.9% (69 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 Jaysun in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jaysun a male name?
Yes, 100.0% of people registered as Jaysun 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 Jaysun still being used today?
Yes. The SSA still recorded Jaysun 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 Jaysun 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.
