Blaz in the 2020 Census
The 2020 Census recorded 140 people with the first name Blaz, 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.

Demographics
Ancestry and ethnicity for Blaz
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Blaz is Hispanic at 55.0%. The next largest groups are White (40.0%) and Two or More Races (2.9%). 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 Blaz 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 Blaz at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Blaz
The name Blaz has its origins in the Slavic languages, particularly in Croatian and Slovenian. It is a variant of the name Blasius, which is derived from the Latin name Blasius meaning "to lisp" or "to stammer."
The name Blasius can be traced back to the 3rd century AD, when it was given to a Christian saint and martyr from Armenia. Saint Blasius, also known as Saint Blaise, is venerated in the Roman Catholic and Eastern Orthodox churches and is the patron saint of throat illnesses.
One of the earliest recorded instances of the name Blaz can be found in the 13th century Croatian epic poem "Osman" by Ivan Gundulić. The poem features a character named Blaz Gundulić, who is believed to be one of the author's ancestors.
Throughout history, there have been several notable individuals who bore the name Blaz. One of the most prominent was Blaz Jurjev Trogranin (1558-1625), a Croatian poet and playwright from Dubrovnik. His works, such as the play "Džuho Krpeta," are considered masterpieces of Renaissance literature in Croatia.
Another notable figure was Blaz Valoič (1597-1668), a Slovenian Roman Catholic priest and scientist who made significant contributions to the field of meteorology. He is credited with being one of the first to measure atmospheric pressure and temperature accurately.
In the 18th century, Blaz Baromić (1722-1800) was a Croatian mathematician and astronomer who worked as a professor at the University of Padua. He is best known for his work on the calculation of comet orbits and the publication of astronomical tables.
Blaz Božič (1904-1977) was a Slovenian painter and graphic artist who is considered one of the most influential figures in Slovenian modern art. His works, which often depicted landscapes and rural scenes, are celebrated for their expressive use of color and unique style.
While the name Blaz has its roots in the Slavic languages, it has also been adopted and used in other cultures over time, albeit less commonly than in its places of origin.

FAQ
Blaz: questions and answers
How many people in the U.S. are named Blaz?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Blaz 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 68,550,868 US residents.
Is Blaz a common name?
We classify Blaz as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Blaz most popular?
The single biggest year for Blaz was 2014, when 5 babies received the name. The fact that the average living Blaz is about 12 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Blaz in the 2020 Census?
The published 2020 Census first-name tables recorded 140 people with the name Blaz, 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 Blaz 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 Blaz?
In the 2020 Census sex table, Blaz appears almost entirely male. Of the 144 people counted with this name, 100.0% 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 Blaz?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Blaz is Hispanic at 55.0%. The next largest groups are White (40.0%) and Two or More Races (2.9%). 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 Blaz most often in the Census?
Hispanic is the largest reported group for people named Blaz in the 2020 Census, accounting for 55.0% (77 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 Blaz in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Blaz a male name?
Yes, 100.0% of people registered as Blaz 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 Blaz still being used today?
Yes. The SSA still recorded Blaz 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 Blaz 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.
