Census
Demorris in the 2020 Census
The 2020 Census recorded 327 people with the first name Demorris, which placed it at #27,781 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 Demorris
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Demorris is Black at 95.4%. The next largest groups are White (1.5%) and Hispanic (1.2%). 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 Demorris 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 Demorris at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Demorris
The given name Demorris has its origins in the ancient Celtic language, dating back to the early medieval period in the British Isles. It is believed to be derived from the Proto-Celtic root words "demo," meaning "people," and "rris," meaning "king" or "ruler." The name can be interpreted as "ruler of the people" or "king of the people."
One of the earliest recorded instances of the name Demorris appears in the "Annals of Ulster," an ancient Irish chronicle dating back to the 5th century AD. The annals mention a Gaelic chieftain named Demorris mac Conall, who ruled over a small kingdom in what is now Northern Ireland.
In the 8th century, a Brythonic prince named Demorris ap Rhodri was a prominent figure in the Kingdom of Gwynedd, located in present-day Wales. He is mentioned in several medieval Welsh manuscripts and is remembered for his efforts to unite the various Welsh kingdoms against the invading Anglo-Saxons.
During the Norman conquest of England in the 11th century, a Norman knight named Demorris de Beaumont fought alongside William the Conqueror at the Battle of Hastings in 1066. He was later granted lands in Warwickshire and became a prominent figure in the Norman aristocracy.
In the 13th century, a Scottish nobleman named Demorris MacDonald played a significant role in the Wars of Scottish Independence against the English. He is mentioned in the chronicles of the Scottish historian John of Fordun as a loyal supporter of William Wallace and Robert the Bruce.
Another notable figure with the name Demorris was an Irish poet and bard who lived in the 16th century. Known as Demorris Ó Dálaigh, he was renowned for his intricate and poetic compositions in the Irish Gaelic language, and his works are still studied and appreciated by scholars of Irish literature.
While the name Demorris has its roots in the Celtic languages and cultures, it has been adopted and adapted by various other cultures throughout history, although it remains relatively uncommon in modern times.

FAQ
Demorris: questions and answers
How many people in the U.S. are named Demorris?
Name Census puts the figure at roughly 357 living Americans. We arrive at this by taking every SSA birth registration for Demorris 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 960,096 US residents.
Is Demorris a common name?
We classify Demorris as "Very Rare". It ranks above 81.1% of all first names in the SSA dataset by living bearers. Across the full history of the data, 375 babies have been registered with this name.
When was Demorris most popular?
The single biggest year for Demorris was 1987, when 19 babies received the name. The fact that the average living Demorris is about 38 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Demorris in the 2020 Census?
The published 2020 Census first-name tables recorded 327 people with the name Demorris, or 0.11 per 100,000 residents. That placed it at #27,781 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 Demorris 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 Demorris?
In the 2020 Census sex table, Demorris leans strongly male. 304 people counted with this name were male (94.1%), compared with 19 female bearers (5.9%). 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 Demorris?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Demorris is Black at 95.4%. The next largest groups are White (1.5%) and Hispanic (1.2%). 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 Demorris most often in the Census?
Black is the largest reported group for people named Demorris in the 2020 Census, accounting for 95.4% (312 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 Demorris in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Demorris a male name?
Yes, 100.0% of people registered as Demorris 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 Demorris still being used today?
Yes. The SSA still recorded Demorris 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 Demorris 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.
