Demetrio in the 2020 Census
The 2020 Census recorded 5,059 people with the first name Demetrio, which placed it at #3,878 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 Demetrio
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Demetrio is Hispanic at 86.1%. The next largest groups are Asian/Pacific Islander (6.7%) and White (4.7%). 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 Demetrio 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 Demetrio at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Demetrio
The name Demetrio originated from the Greek language and culture, dating back to ancient times. It is derived from the Greek name Demetrios, which is a combination of the words "de" meaning "earth" and "meter" meaning "mother." Thus, the name Demetrio can be interpreted as "son of the earth mother" or "son of the grain goddess Demeter."
In Greek mythology, Demeter was the goddess of agriculture, fertility, and the harvest. She was one of the most revered deities in the Greek pantheon, and her name was often invoked during agricultural rituals and festivities. The name Demetrio was likely given to male children as a way to honor the goddess and ensure a bountiful harvest.
The earliest recorded use of the name Demetrio can be traced back to ancient Greek texts and inscriptions from the 5th century BC. One notable figure who bore this name was Demetrio I Poliorcetes, a king of Macedon who lived from 337 BC to 283 BC. He was known as a skilled military strategist and was nicknamed "the Besieger" for his prowess in siege warfare.
Another historical figure named Demetrio was Demetrio Falereo, an Athenian orator, statesman, and philosopher who lived from around 350 BC to 280 BC. He was renowned for his eloquence and served as the governor of Athens for a time.
In the realm of religion, one of the most famous individuals named Demetrio was Saint Demetrius of Thessalonica, a Christian martyr who lived in the late 3rd century AD. He was a Roman soldier who was executed for his Christian faith, and his veneration spread throughout the Byzantine Empire and Eastern Orthodox Church.
During the Renaissance period, a notable figure named Demetrio Calcondila lived from around 1424 to 1511. He was a Greek scholar and teacher who played a significant role in the revival of Greek studies in Italy and the spread of humanism.
Another prominent individual with the name Demetrio was Demetrio Vestier, an Italian artist and architect who lived from 1541 to 1603. He was known for his work on various churches and palaces in Rome, and his architectural designs were influenced by the Classical and Renaissance styles.
Throughout history, the name Demetrio has maintained its connection to Greek culture and heritage, symbolizing the enduring influence of ancient mythology and traditions. It has been carried by individuals from diverse backgrounds, from kings and scholars to saints and artists, each leaving their mark on the world in their own unique way.

FAQ
Demetrio: questions and answers
How many people in the U.S. are named Demetrio?
Name Census puts the figure at roughly 2,404 living Americans. We arrive at this by taking every SSA birth registration for Demetrio 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 142,577 US residents.
Is Demetrio a common name?
We classify Demetrio as "Rare". It ranks above 94.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 3,047 babies have been registered with this name.
When was Demetrio most popular?
The single biggest year for Demetrio was 1999, when 88 babies received the name. The fact that the average living Demetrio 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 Demetrio in the 2020 Census?
The published 2020 Census first-name tables recorded 5,059 people with the name Demetrio, or 1.68 per 100,000 residents. That placed it at #3,878 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 Demetrio 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 Demetrio?
In the 2020 Census sex table, Demetrio appears almost entirely male. Of the 5,064 people counted with this name, 99.6% were male and only a very small share were female. 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 Demetrio?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Demetrio is Hispanic at 86.1%. The next largest groups are Asian/Pacific Islander (6.7%) and White (4.7%). 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 Demetrio most often in the Census?
Hispanic is the largest reported group for people named Demetrio in the 2020 Census, accounting for 86.1% (4,357 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 Demetrio in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Demetrio a male name?
Yes, 100.0% of people registered as Demetrio 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 Demetrio still being used today?
Yes. The SSA still recorded Demetrio 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 Demetrio 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.
