Census
Casyn in the 2020 Census
The 2020 Census recorded 374 people with the first name Casyn, which placed it at #25,370 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 Casyn
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Casyn is White at 69.0%. The next largest groups are Black (12.3%) and Hispanic (8.3%). 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 Casyn 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 Casyn at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Casyn
The name Casyn is believed to have originated from the ancient Sumerian language, which was spoken in the region of Mesopotamia (modern-day Iraq) around 3500 BC. It is derived from the Sumerian word "kasinu," which means "powerful" or "strong." The earliest known mention of the name Casyn can be found in cuneiform inscriptions on clay tablets from the city of Ur, dating back to the 3rd millennium BC.
In ancient Sumerian mythology, Casyn was also the name of a minor deity associated with strength and protection. While not widely worshipped, this deity was often invoked by warriors and soldiers before going into battle. The name Casyn later spread to other cultures and civilizations that came into contact with the Sumerians, such as the Akkadians and Babylonians.
One of the earliest recorded individuals with the name Casyn was a Sumerian king who ruled over the city-state of Lagash around 2500 BC. Historical records indicate that he was a successful military leader who expanded the boundaries of his kingdom through conquests. However, not much is known about his personal life or specific reign.
In the 1st century AD, there was a Roman soldier named Casyn who served under the Emperor Tiberius. He is mentioned in several historical accounts for his bravery and leadership during the campaigns against the Germanic tribes. Casyn was reportedly awarded several military honors for his service.
During the medieval period, a significant figure with the name Casyn was a Frankish nobleman who lived in the 8th century AD. He was a trusted advisor and military commander under the Carolingian dynasty, serving under Charlemagne. Historical records describe him as a skilled strategist and a fierce warrior on the battlefield.
Another notable individual with the name Casyn was a Persian poet and philosopher who lived in the 10th century AD. He is best known for his collection of poems and writings on the nature of existence and the human condition. His works were widely read and influential in the Persian literary tradition.
In the 16th century, there was a Spanish explorer named Casyn who was part of the expeditions that explored and mapped the coastlines of South America. He is credited with discovering several islands and natural harbors, which were crucial for the development of trade routes and settlements in the region.

FAQ
Casyn: questions and answers
How many people in the U.S. are named Casyn?
Name Census puts the figure at roughly 514 living Americans. We arrive at this by taking every SSA birth registration for Casyn 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 666,837 US residents.
Is Casyn a common name?
We classify Casyn as "Very Rare". It ranks above 84.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 518 babies have been registered with this name.
When was Casyn most popular?
The single biggest year for Casyn was 2014, when 46 babies received the name. The fact that the average living Casyn is about 11 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Casyn in the 2020 Census?
The published 2020 Census first-name tables recorded 374 people with the name Casyn, or 0.12 per 100,000 residents. That placed it at #25,370 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 Casyn 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 Casyn?
In the 2020 Census sex table, Casyn leans strongly male. 308 people counted with this name were male (82.8%), compared with 64 female bearers (17.2%). 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 Casyn?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Casyn is White at 69.0%. The next largest groups are Black (12.3%) and Hispanic (8.3%). 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 Casyn most often in the Census?
White is the largest reported group for people named Casyn in the 2020 Census, accounting for 69.0% (258 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 Casyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Casyn a male name?
Yes, 95.0% of people registered as Casyn 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 Casyn still being used today?
Yes. The SSA still recorded Casyn 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 Casyn 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.
