Census
Delancy in the 2020 Census
The 2020 Census recorded 140 people with the first name Delancy, which placed it at #47,034 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 Delancy

The bar chart below shows how people with the first name Delancy 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 Delancy at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Delancy
The name Delancy is derived from the French language, specifically the phrase "de l'Ancy," which means "from Ancy." This phrase was likely used to indicate a person's place of origin or residence, with "Ancy" being a town in the Burgundy region of France.
In the Middle Ages, it was common for people to be identified by their place of origin or residence, particularly in rural areas. As such, the name Delancy likely originated as a descriptive surname for someone who hailed from the town of Ancy.
The earliest recorded use of the name Delancy dates back to the 14th century in France. One of the earliest known individuals with this name was Jean Delancy, a French nobleman who lived in the late 14th century and served as a knight in the court of King Charles VI.
Another notable figure with the name Delancy was Étienne Delancy, a French explorer and navigator who accompanied Jacques Cartier on his voyages to the Americas in the 16th century. Delancy played a crucial role in mapping and charting the St. Lawrence River and the Gulf of St. Lawrence.
In the 17th century, the Delancy name gained prominence in the Netherlands through the Dutch Huguenot diaspora. One of the most influential figures with this name was Jacques Delancy, a Huguenot merchant and banker who fled France during the religious persecution of Protestants and settled in Amsterdam.
The name Delancy also found its way to England, where it was anglicized to "Delancey." One of the earliest recorded instances of this spelling was Sir Oliver Delancey, an English military officer and colonial administrator who served as the Lieutenant Governor of New York in the early 18th century.
Another notable figure with the name Delancy was Étienne-Nicolas Delancy, a French Jesuit priest and missionary who traveled to China in the late 17th century. Delancy played a significant role in bridging the cultural gap between China and the West through his writings and translations.
These are just a few examples of the rich history and diverse backgrounds associated with the name Delancy.

FAQ
Delancy: questions and answers
How many people in the U.S. are named Delancy?
Name Census puts the figure at roughly 25 living Americans. We arrive at this by taking every SSA birth registration for Delancy 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 13,710,174 US residents.
Is Delancy a common name?
We classify Delancy as "Very Rare". It ranks above 43.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 26 babies have been registered with this name.
When was Delancy most popular?
The single biggest year for Delancy was 2013, when 6 babies received the name. The fact that the average living Delancy is about 18 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Delancy in the 2020 Census?
The published 2020 Census first-name tables recorded 140 people with the name Delancy, or 0.05 per 100,000 residents. That placed it at #47,034 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 Delancy 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 Delancy?
The 2020 Census sex table shows Delancy on both sides of the split. Of the 134 people counted with this name, 60 were male (44.8%) and 74 were female (55.2%). 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 Delancy?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Delancy is White at 42.1%. The next largest groups are Black (40.0%) and Hispanic (10.7%). 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 Delancy most often in the Census?
White is the largest reported group for people named Delancy in the 2020 Census, accounting for 42.1% (59 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 Delancy in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Delancy a female name?
Yes, 80.8% of people registered as Delancy in the SSA data are female. 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 Delancy still being used today?
Yes. The SSA still recorded Delancy 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 Delancy 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.
