Census
Dyllon in the 2020 Census
The 2020 Census recorded 1,136 people with the first name Dyllon, which placed it at #11,344 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 Dyllon
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dyllon is White at 68.8%. The next largest groups are Black (10.7%) and Hispanic (10.5%). 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 Dyllon 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 Dyllon at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Dyllon
The given name Dyllon has its origins in the Welsh language and culture, dating back to the early medieval period around the 6th century AD. It is believed to be derived from the Welsh word "dyl," meaning "faithful" or "true," combined with the diminutive suffix "-on." This suggests that the name may have originally been a nickname or a term of endearment for someone who was considered trustworthy or loyal.
In its earliest recorded forms, the name appeared as "Dyllon" or "Dillon" in various ancient Welsh manuscripts and genealogical records. It was particularly prevalent among the noble families and ruling dynasties of Wales, indicating its association with nobility and prestige.
One of the earliest known historical figures to bear the name Dyllon was a Welsh prince and warrior who lived in the late 6th century. He was recorded in the annals of the time as Dyllon ap Rhain, a prominent leader who fought against the invading Saxons and played a crucial role in defending the Welsh territories.
Another notable figure with the name Dyllon was a 9th-century Welsh monk and scholar known as Dyllon of Bangor. He was renowned for his religious writings and his contributions to the preservation of Welsh literature and culture during a turbulent period in the country's history.
In the 11th century, a influential figure named Dyllon ap Cadwgan emerged as a powerful Welsh nobleman and military commander. He was a key figure in the struggle against Norman invaders and played a pivotal role in the Welsh resistance against English dominance.
During the 12th century, a Welsh bard and poet named Dyllon Aylwyn gained recognition for his poetic works celebrating Welsh culture and tradition. His compositions were widely circulated and helped to preserve the rich literary heritage of Wales.
In the 15th century, a renowned Welsh scholar and Renaissance humanist, Dyllon ap Rhys, made significant contributions to the study of classical literature and philosophy. His translations and commentaries on ancient Greek and Roman texts were highly influential during the Renaissance period.
These are just a few examples of historical figures who bore the name Dyllon, reflecting its longstanding presence and cultural significance within the Welsh tradition. While the name has evolved and adapted over time, its roots can be traced back to the early medieval period, where it emerged as a symbol of loyalty, nobility, and cultural pride among the Welsh people.

FAQ
Dyllon: questions and answers
How many people in the U.S. are named Dyllon?
Name Census puts the figure at roughly 1,244 living Americans. We arrive at this by taking every SSA birth registration for Dyllon 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 275,526 US residents.
Is Dyllon a common name?
We classify Dyllon as "Rare". It ranks above 91.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,267 babies have been registered with this name.
When was Dyllon most popular?
The single biggest year for Dyllon was 1992, when 100 babies received the name. The fact that the average living Dyllon is about 26 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Dyllon in the 2020 Census?
The published 2020 Census first-name tables recorded 1,136 people with the name Dyllon, or 0.38 per 100,000 residents. That placed it at #11,344 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 Dyllon 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 Dyllon?
In the 2020 Census sex table, Dyllon leans strongly male. 1,102 people counted with this name were male (97.2%), compared with 32 female bearers (2.8%). 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 Dyllon?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dyllon is White at 68.8%. The next largest groups are Black (10.7%) and Hispanic (10.5%). 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 Dyllon most often in the Census?
White is the largest reported group for people named Dyllon in the 2020 Census, accounting for 68.8% (782 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 Dyllon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dyllon a male name?
Yes, 100.0% of people registered as Dyllon 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 Dyllon still being used today?
Yes. The SSA still recorded Dyllon 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 Dyllon 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.
