Kaston in the 2020 Census
The 2020 Census recorded 334 people with the first name Kaston, which placed it at #27,416 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 Kaston
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaston is White at 67.4%. The next largest groups are Black (13.5%) and Two or More Races (7.2%). 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 Kaston 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 Kaston at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kaston
The name Kaston has its origins in the ancient Germanic language, with roots dating back to the 5th century CE. It is believed to be derived from the Old Germanic word "kast," meaning "strong" or "brave." This name was likely first used by the various Germanic tribes that inhabited the regions of modern-day Germany, the Netherlands, and parts of Scandinavia.
One of the earliest recorded uses of the name Kaston can be found in the Codex Argenteus, a 6th-century manuscript containing a translation of the Bible into the Gothic language. In this text, the name appears as "Kastons," referring to a Gothic warrior or chieftain.
During the Middle Ages, the name Kaston gained popularity among the nobility and aristocracy of various Germanic kingdoms. It was often associated with strength, valor, and a warrior spirit. Several historical figures from this period bore the name, including Kaston von Trier, a renowned knight and crusader who participated in the Third Crusade in the late 12th century.
In the Renaissance era, the name Kaston experienced a resurgence in popularity, particularly in the Low Countries and northern Germany. One notable figure from this time was Kaston van Eyck, a Flemish painter and one of the most significant artists of the Northern Renaissance, born in 1390.
During the 17th and 18th centuries, the name Kaston spread beyond its Germanic roots and was adopted in various European cultures. In England, for instance, a notable figure was Kaston Calvert, the 5th Baron Baltimore, who played a significant role in the early colonization of Maryland in the mid-17th century.
Another prominent individual with the name Kaston was Kaston Pulaski, a Polish-born military leader and revolutionary who fought alongside the American colonists during the American Revolutionary War. He was born in 1745 and is celebrated as a hero in both Poland and the United States for his contributions to the fight for independence.
In more recent times, the name Kaston has continued to be used, though with varying degrees of popularity across different regions and cultures. One of the most well-known figures bearing this name was Kaston Kutcher, an American actor and entrepreneur born in 1978, known for his roles in popular television shows and films.

FAQ
Kaston: questions and answers
How many people in the U.S. are named Kaston?
Name Census puts the figure at roughly 380 living Americans. We arrive at this by taking every SSA birth registration for Kaston 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 901,985 US residents.
Is Kaston a common name?
We classify Kaston as "Very Rare". It ranks above 81.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 383 babies have been registered with this name.
When was Kaston most popular?
The single biggest year for Kaston was 2023, when 28 babies received the name. The fact that the average living Kaston 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 Kaston in the 2020 Census?
The published 2020 Census first-name tables recorded 334 people with the name Kaston, or 0.11 per 100,000 residents. That placed it at #27,416 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 Kaston 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 Kaston?
In the 2020 Census sex table, Kaston leans strongly male. 314 people counted with this name were male (96.3%), compared with 12 female bearers (3.7%). 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 Kaston?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaston is White at 67.4%. The next largest groups are Black (13.5%) and Two or More Races (7.2%). 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 Kaston most often in the Census?
White is the largest reported group for people named Kaston in the 2020 Census, accounting for 67.4% (225 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 Kaston in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaston a male name?
Yes, 100.0% of people registered as Kaston 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 Kaston still being used today?
Yes. The SSA still recorded Kaston 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 Kaston 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.
