Census
Jaison in the 2020 Census
The 2020 Census recorded 1,800 people with the first name Jaison, which placed it at #8,129 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 Jaison
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jaison is White at 24.9%. The next largest groups are Hispanic (24.1%) and Asian/Pacific Islander (23.6%). 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 Jaison 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 Jaison at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Jaison
The name Jaison is derived from the Hebrew name Jason, which is a variant of the name Jasun or Iasōn. The name Jason is believed to have originated from the Greek word "iasthai," meaning "to heal" or "to cure." It is thought to be connected to the Greek mythological character Jason, the leader of the Argonauts who went on a quest to retrieve the Golden Fleece.
The name Jaison is believed to have emerged as a variant spelling during the Middle Ages, particularly in regions where the letter "J" was used interchangeably with the letter "I." This variation in spelling was common during this time period, as standardized spellings were not yet widely established.
One of the earliest recorded instances of the name Jaison can be found in the 14th century, when a French knight named Jaison de Rouville was mentioned in historical records from the Hundred Years' War. Another notable figure was Jaison de Flanders, a Flemish merchant and explorer who traveled to the Mediterranean region in the late 15th century.
In the 16th century, the name Jaison gained popularity among Protestant families in England and Scotland, possibly due to its association with the biblical figure Jason, who is mentioned in the Book of Acts as a kinsman of the Apostle Paul.
One of the most famous bearers of the name Jaison was Jaison de Mayerne (1573-1655), a Swiss-born physician who served as the personal physician to King James I of England and later became the president of the Royal College of Physicians in London.
Another notable figure was Jaison Atherton (1598-1654), an English clergyman and writer who served as the Bishop of Waterford and Lismore in Ireland during the 17th century.
In the 18th century, Jaison Denton (1715-1781) was a prominent British naval officer who participated in several battles during the Seven Years' War and the American Revolutionary War.
During the 19th century, Jaison Thorndike (1818-1892) was an American lawyer and politician who served as a member of the Massachusetts State Legislature and later became the mayor of Lowell, Massachusetts.
One of the more recent historical figures with the name Jaison was Jaison Robards (1890-1964), an American actor who gained fame for his performances in Broadway productions and Hollywood films during the early 20th century.

FAQ
Jaison: questions and answers
How many people in the U.S. are named Jaison?
Name Census puts the figure at roughly 1,717 living Americans. We arrive at this by taking every SSA birth registration for Jaison 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 199,624 US residents.
Is Jaison a common name?
We classify Jaison as "Rare". It ranks above 93.1% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,769 babies have been registered with this name.
When was Jaison most popular?
The single biggest year for Jaison was 2008, when 59 babies received the name. The fact that the average living Jaison is about 28 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Jaison in the 2020 Census?
The published 2020 Census first-name tables recorded 1,800 people with the name Jaison, or 0.60 per 100,000 residents. That placed it at #8,129 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 Jaison 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 Jaison?
In the 2020 Census sex table, Jaison appears almost entirely male. Of the 1,792 people counted with this name, 99.4% 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 Jaison?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jaison is White at 24.9%. The next largest groups are Hispanic (24.1%) and Asian/Pacific Islander (23.6%). 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 Jaison most often in the Census?
White is the largest reported group for people named Jaison in the 2020 Census, accounting for 24.9% (449 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 Jaison in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jaison a male name?
Yes, 100.0% of people registered as Jaison 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 Jaison still being used today?
Yes. The SSA still recorded Jaison 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 Jaison 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. You can read the full calculation on our methodology page.
