Census
Deloise in the 2020 Census
The 2020 Census recorded 860 people with the first name Deloise, which placed it at #13,890 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.

Demographics
Ancestry and ethnicity for Deloise
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Deloise is Black at 82.3%. The next largest groups are White (12.9%) and Two or More Races (2.6%). 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 Deloise 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 Deloise at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Deloise
The given name Deloise has its roots in the Old French language, originating around the 12th century. It is believed to be derived from the combination of the words "de" meaning "from" and "lois" meaning "law." This suggests the name may have referred to someone associated with the legal system or someone who upheld the law.
During the Middle Ages, the name Deloise was popular in parts of France, particularly in the northern regions. It was also found in some areas of England, likely due to the Norman influence after the conquest in 1066. Early spellings of the name included Deloyce, Deloisse, and Deloïse.
One of the earliest recorded instances of the name Deloise can be found in a 13th-century French manuscript, where it was used to refer to a noblewoman from the Île-de-France region. However, there are no known references to the name in major religious texts or ancient scriptures.
Throughout history, several notable individuals have borne the name Deloise. One of the earliest was Deloise de Lannion (c. 1230 - 1295), a French noblewoman and landowner who played a significant role in the local politics of Brittany during the late 13th century.
Another prominent figure was Deloise de Montfort (1324 - 1388), a member of the powerful Montfort family in medieval France. She was known for her involvement in the Breton War of Succession and her influence in the region's political affairs.
In the 15th century, Deloise de Valois (1456 - 1520) was a French noblewoman and courtier at the court of King Louis XII. She held significant influence during her time and was known for her patronage of the arts.
During the Renaissance period, Deloise de Montalembert (1540 - 1618) was a French writer and poet who contributed to the literary circles of her time. Her works explored themes of love, nature, and spirituality.
In more recent history, Deloise Flint (1882 - 1964) was an American painter and artist known for her impressionistic landscapes and portraits. She was a prominent figure in the art scene of the early 20th century and exhibited her works widely across the United States.

FAQ
Deloise: questions and answers
How many people in the U.S. are named Deloise?
Name Census puts the figure at roughly 1,011 living Americans. We arrive at this by taking every SSA birth registration for Deloise 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 339,025 US residents.
Is Deloise a common name?
We classify Deloise as "Rare". It ranks above 90.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,887 babies have been registered with this name.
When was Deloise most popular?
The single biggest year for Deloise was 1953, when 86 babies received the name. The fact that the average living Deloise is about 71 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Deloise in the 2020 Census?
The published 2020 Census first-name tables recorded 860 people with the name Deloise, or 0.28 per 100,000 residents. That placed it at #13,890 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 Deloise 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 Deloise?
In the 2020 Census sex table, Deloise appears almost entirely female. Of the 858 people counted with this name, 99.4% were female and only a very small share were male. 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 Deloise?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Deloise is Black at 82.3%. The next largest groups are White (12.9%) and Two or More Races (2.6%). 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 Deloise most often in the Census?
Black is the largest reported group for people named Deloise in the 2020 Census, accounting for 82.3% (708 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 Deloise in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Deloise a female name?
Yes, 100.0% of people registered as Deloise 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 Deloise still being used today?
Yes. The SSA still recorded Deloise 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 Deloise 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.
