Census
Adelmo in the 2020 Census
The 2020 Census recorded 417 people with the first name Adelmo, which placed it at #23,447 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 Adelmo
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Adelmo is Hispanic at 75.1%. The next largest groups are White (18.0%) and Asian/Pacific Islander (6.0%). 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 Adelmo 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 Adelmo at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Adelmo
The name Adelmo is of Italian origin, derived from the Germanic roots "adal", meaning noble or aristocratic, and "helm", meaning helmet or protection. It emerged during the Middle Ages in various regions of Italy, particularly in the northern regions such as Lombardy and Emilia-Romagna.
One of the earliest recorded instances of the name Adelmo dates back to the 8th century, when an Italian monk and scholar named Adelmo di Ferrara (720-790) gained recognition for his contributions to the fields of theology and philosophy. He was a prominent figure in the Church and is remembered for his writings on various religious and intellectual subjects.
In the 11th century, Adelmo di Leffe (1020-1090) was a renowned Benedictine monk and abbot from the Monastery of Leffe in Bergamo, Italy. He was known for his efforts in promoting monastic reforms and his dedication to religious life.
During the Renaissance period, Adelmo Filonardi (1470-1540) was an Italian diplomat and cardinal who served as the Bishop of Montefiascone and Corneto from 1520 until his death. He played an influential role in papal politics and was involved in various diplomatic missions.
In the 17th century, Adelmo Venturi (1620-1690) was an Italian painter and architect from Bologna. He is best known for his contributions to the Baroque architectural style and his paintings adorning several churches in Bologna and neighboring regions.
Another notable figure with the name Adelmo was Adelmo Bultrini (1888-1915), an Italian soldier and war hero who fought in World War I. He was awarded the Gold Medal of Military Valor posthumously for his bravery and sacrifice during the Battle of Monfalcone in 1915.

FAQ
Adelmo: questions and answers
How many people in the U.S. are named Adelmo?
Name Census puts the figure at roughly 3 living Americans. We arrive at this by taking every SSA birth registration for Adelmo 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 114,251,446 US residents.
Is Adelmo a common name?
We classify Adelmo as "Very Rare". It ranks above 4.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 13 babies have been registered with this name.
When was Adelmo most popular?
The single biggest year for Adelmo was 1929, when 7 babies received the name. The fact that the average living Adelmo is about 82 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Adelmo in the 2020 Census?
The published 2020 Census first-name tables recorded 417 people with the name Adelmo, or 0.14 per 100,000 residents. That placed it at #23,447 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 Adelmo 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 Adelmo?
In the 2020 Census sex table, Adelmo leans strongly male. 420 people counted with this name were male (98.1%), compared with 8 female bearers (1.9%). 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 Adelmo?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Adelmo is Hispanic at 75.1%. The next largest groups are White (18.0%) and Asian/Pacific Islander (6.0%). 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 Adelmo most often in the Census?
Hispanic is the largest reported group for people named Adelmo in the 2020 Census, accounting for 75.1% (313 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 Adelmo in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Adelmo a male name?
Yes, 100.0% of people registered as Adelmo 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 Adelmo still being used today?
Yes. The SSA still recorded Adelmo 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 Adelmo 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.
