Census
Jensyn in the 2020 Census
The 2020 Census recorded 715 people with the first name Jensyn, which placed it at #15,935 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 Jensyn
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jensyn is White at 84.2%. The next largest groups are Hispanic (5.6%) and Two or More Races (5.6%). 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 Jensyn 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 Jensyn at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Jensyn
The name Jensyn has its roots in the Old Norse language, which was spoken by the Vikings and Scandinavian people during the Viking Age, approximately from the 8th to the 11th century. It is believed to be derived from the Old Norse name "Jenssøn," which means "son of Jens." Jens is a variant of the name John, which is derived from the Hebrew name Yohanan, meaning "Yahweh is gracious."
One of the earliest recorded instances of the name Jensyn dates back to the 12th century, when it appeared in the Icelandic Sagas, a collection of literary works that documented the lives and adventures of the early Scandinavian settlers in Iceland. The name was particularly popular among the Norse and Danish Vikings, who spread it throughout the regions they explored and conquered.
Throughout history, several notable individuals have borne the name Jensyn. One of the earliest was Jensyn the Red (c. 950-1010), a legendary Viking warrior and explorer who is said to have led expeditions to Greenland and the North American continent, predating the voyages of Christopher Columbus by several centuries. Another prominent figure was Jensyn Eriksson (c. 1210-1275), a Danish statesman and military commander who played a crucial role in the consolidation of Danish power in the Baltic region during the 13th century.
In the 15th century, Jensyn Thorvaldsson (c. 1425-1490) was a renowned Icelandic scholar and poet, renowned for his contributions to the preservation of Iceland's literary heritage and the study of Old Norse language and culture. A century later, Jensyn Magnusson (c. 1570-1635) was a Swedish naval commander and explorer who led several expeditions to the Arctic regions, contributing to the mapping and exploration of the Northern seas.
More recently, Jensyn Bjornson (1856-1932) was a Norwegian-American author and playwright, known for his works that celebrated the lives and struggles of Norwegian immigrants in the United States. His plays and novels played a significant role in shaping the cultural identity of the Norwegian-American community in the late 19th and early 20th centuries.
While the name Jensyn has its origins in Scandinavia and the Viking Age, it has since spread to various parts of the world, particularly through the diaspora of Scandinavian and Norse populations. Today, it continues to be a name that carries a rich historical and cultural significance, reflecting the enduring legacy of the Vikings and their impact on the world.

FAQ
Jensyn: questions and answers
How many people in the U.S. are named Jensyn?
Name Census puts the figure at roughly 1,014 living Americans. We arrive at this by taking every SSA birth registration for Jensyn 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 338,022 US residents.
Is Jensyn a common name?
We classify Jensyn as "Rare". It ranks above 90.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,024 babies have been registered with this name.
When was Jensyn most popular?
The single biggest year for Jensyn was 2019, when 83 babies received the name. The fact that the average living Jensyn is about 12 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Jensyn in the 2020 Census?
The published 2020 Census first-name tables recorded 715 people with the name Jensyn, or 0.24 per 100,000 residents. That placed it at #15,935 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 Jensyn 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 Jensyn?
The 2020 Census sex table shows Jensyn on both sides of the split. Of the 710 people counted with this name, 158 were male (22.3%) and 552 were female (77.7%). 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 Jensyn?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Jensyn is White at 84.2%. The next largest groups are Hispanic (5.6%) and Two or More Races (5.6%). 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 Jensyn most often in the Census?
White is the largest reported group for people named Jensyn in the 2020 Census, accounting for 84.2% (602 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 Jensyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jensyn a female name?
Yes, 74.0% of people registered as Jensyn in the SSA data are female. 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 Jensyn still being used today?
Yes. The SSA still recorded Jensyn 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 Jensyn 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.
