Census
Dequincy in the 2020 Census
The 2020 Census recorded 276 people with the first name Dequincy, which placed it at #31,162 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 Dequincy
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dequincy is Black at 92.8%. The next largest groups are Two or More Races (4.0%) and White (1.8%). 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 Dequincy 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 Dequincy at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Dequincy
The given name Dequincy has its origins in the French language, with its roots tracing back to the Middle Ages. The name is derived from the French surname "de Quincy," which was borne by several notable families in medieval France.
The name likely originated from the town of Quincy, located in the region of Burgundy, France. This town's name is believed to have its roots in the Latin word "quintus," meaning "fifth," suggesting a connection to the fifth milestone on an ancient Roman road.
One of the earliest recorded instances of the name Dequincy can be found in the historical records of the 12th century. During this period, a nobleman named Renaud de Quincy played a prominent role in the Third Crusade, serving as a close advisor to King Richard the Lionheart.
In the 13th century, a figure named Saher de Quincy held the position of Earl of Winchester in England. He was a powerful nobleman and a participant in the Baron's War against King John, which led to the signing of the Magna Carta in 1215.
Moving forward to the 16th century, the name Dequincy gained literary significance through the works of the English writer Thomas de Quincey (1785-1859). He is best known for his autobiographical work "Confessions of an English Opium-Eater," which explored his addiction to opium and provided insights into the literary world of the Romantic era.
Another notable bearer of the name was Edmund de Quincy (1808-1877), an American writer and journalist who played a significant role in the early years of the American literary scene. He co-founded the New York Evening Post and was an advocate for the abolition of slavery.
In the 20th century, the name Dequincy gained further recognition through the works of the American novelist Dequincy Lezine (1923-2010). He authored several novels and short stories, including "Paradoxes of Freedom" and "The Burglar's Dilemma," exploring themes of social justice and moral dilemmas.
While the name Dequincy has its roots in French nobility and literary circles, it has since gained broader appeal and usage across various cultures and regions, though its historical origins remain closely tied to its French and European heritage.

FAQ
Dequincy: questions and answers
How many people in the U.S. are named Dequincy?
Name Census puts the figure at roughly 362 living Americans. We arrive at this by taking every SSA birth registration for Dequincy 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 946,835 US residents.
Is Dequincy a common name?
We classify Dequincy as "Very Rare". It ranks above 81.3% 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 Dequincy most popular?
The single biggest year for Dequincy was 1992, when 19 babies received the name. The fact that the average living Dequincy is about 34 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Dequincy in the 2020 Census?
The published 2020 Census first-name tables recorded 276 people with the name Dequincy, or 0.09 per 100,000 residents. That placed it at #31,162 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 Dequincy 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 Dequincy?
In the 2020 Census sex table, Dequincy leans strongly male. 268 people counted with this name were male (95.7%), compared with 12 female bearers (4.3%). 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 Dequincy?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Dequincy is Black at 92.8%. The next largest groups are Two or More Races (4.0%) and White (1.8%). 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 Dequincy most often in the Census?
Black is the largest reported group for people named Dequincy in the 2020 Census, accounting for 92.8% (256 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 Dequincy in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dequincy a male name?
Yes, 100.0% of people registered as Dequincy 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 Dequincy still being used today?
Yes. The SSA still recorded Dequincy 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 Dequincy 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.
