Census
Thiago in the 2020 Census
The 2020 Census recorded 10,664 people with the first name Thiago, which placed it at #2,358 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 Thiago
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thiago is Hispanic at 70.6%. The next largest groups are White (25.0%) and Black (2.0%). 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 Thiago 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 Thiago at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Thiago
The name Thiago is derived from the Greek name Theodoros, which means "gift of God." The name has its roots in ancient Greek culture and can be traced back to the 5th century BC.
The name Thiago is a variant of the Spanish name Tiago, which is a form of the name Santiago, meaning "Saint James." It is believed that the name was introduced to Spain by the Visigoths, a Germanic tribe that invaded the Iberian Peninsula in the 5th century AD.
One of the earliest recorded instances of the name Thiago can be found in the "Codex Calixtinus," a 12th-century manuscript that documents the life and miracles of St. James the Great. The name was also mentioned in various medieval texts and chronicles from the Iberian Peninsula.
Throughout history, there have been several notable individuals named Thiago. One of the earliest was Thiago of Seville, a 13th-century Spanish theologian and philosopher who wrote extensively on Aristotelian philosophy. Another notable figure was Thiago de Montemor, a 16th-century Portuguese composer and musician who served at the court of King John III.
In the 20th century, Thiago Braga (1924-2016) was a renowned Brazilian painter and sculptor known for his abstract and geometric works. Thiago Silva (born 1984) is a Brazilian professional footballer who has played for various clubs, including AC Milan and Paris Saint-Germain, and has represented the Brazilian national team.
Another notable Thiago is Thiago Alcântara (born 1991), a Spanish professional footballer who currently plays for Liverpool FC in the Premier League. He is the son of former Brazilian footballer Mazinho and has represented both the Spanish and Brazilian national teams.
The name Thiago has maintained its popularity over the centuries, particularly in Portuguese and Spanish-speaking countries, where it is often associated with a sense of strength, nobility, and divine favor.

FAQ
Thiago: questions and answers
How many people in the U.S. are named Thiago?
Name Census puts the figure at roughly 29,171 living Americans. We arrive at this by taking every SSA birth registration for Thiago 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 11,750 US residents.
Is Thiago a common name?
We classify Thiago as "Uncommon". It ranks above 98.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 29,375 babies have been registered with this name.
When was Thiago most popular?
The single biggest year for Thiago was 2024, when 5,295 babies received the name. The fact that the average living Thiago is about 6 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Thiago in the 2020 Census?
The published 2020 Census first-name tables recorded 10,664 people with the name Thiago, or 3.53 per 100,000 residents. That placed it at #2,358 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 Thiago 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 Thiago?
In the 2020 Census sex table, Thiago appears almost entirely male. Of the 10,663 people counted with this name, 99.8% 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 Thiago?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thiago is Hispanic at 70.6%. The next largest groups are White (25.0%) and Black (2.0%). 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 Thiago most often in the Census?
Hispanic is the largest reported group for people named Thiago in the 2020 Census, accounting for 70.6% (7,530 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 Thiago in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Thiago a male name?
Yes, 99.9% of people registered as Thiago 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 Thiago still being used today?
Yes. The SSA still recorded Thiago 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 Thiago 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.
