Census
Kazia in the 2020 Census
The 2020 Census recorded 356 people with the first name Kazia, which placed it at #26,232 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 Kazia
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kazia is White at 42.7%. The next largest groups are Black (32.9%) and Asian/Pacific Islander (7.9%). 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 Kazia 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 Kazia at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kazia
The name Kazia is believed to have its origins in the Slavic languages, specifically in the Polish and Czech cultures. The earliest recorded instances of the name date back to the 13th century.
Kazia is thought to be a diminutive or pet form derived from the Slavic name Kazimierz, which itself is a combination of the Slavic elements "kaz" meaning "to destroy" and "miru" meaning "peace" or "world." The name was likely intended to convey the sense of "destroying peace" or "world-destroyer."
One of the earliest notable figures to bear the name Kazia was Kazia of Halicz, a 13th-century Ruthenian princess and the daughter of Prince Daniel of Galicia and his wife, Anna of Novgorod. Kazia played a significant role in the political alliances and conflicts of her time.
In the 15th century, Kazia Gruszczyńska was a Polish noblewoman and landowner who wielded considerable influence in the region of Greater Poland. She was known for her involvement in various legal disputes and her efforts to protect her family's assets and property rights.
During the 16th century, Kazia Słupska was a Polish nun and abbess of the Benedictine convent in Staniątki, near Kraków. She was renowned for her piety and her dedication to the religious community.
In the 17th century, Kazia Radziejowska was a Polish poet and writer who authored several works of religious poetry and devotional literature. Her poems were widely circulated and admired within the Polish literary circles of her time.
Another notable figure bearing the name Kazia was Kazia Curie-Skłodowska, a 19th-century Polish-born scientist and the daughter of the renowned physicists Marie and Pierre Curie. Although she did not achieve the same level of fame as her parents, Kazia contributed to the field of chemistry and worked alongside her mother in the laboratory.
While the name Kazia has its roots in the Slavic cultures, its usage has spread to various other regions and cultures over the centuries, albeit with varying degrees of popularity and significance.

FAQ
Kazia: questions and answers
How many people in the U.S. are named Kazia?
Name Census puts the figure at roughly 321 living Americans. We arrive at this by taking every SSA birth registration for Kazia 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 1,067,771 US residents.
Is Kazia a common name?
We classify Kazia as "Very Rare". It ranks above 80% of all first names in the SSA dataset by living bearers. Across the full history of the data, 331 babies have been registered with this name.
When was Kazia most popular?
The single biggest year for Kazia was 1987, when 37 babies received the name. The fact that the average living Kazia is about 27 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Kazia in the 2020 Census?
The published 2020 Census first-name tables recorded 356 people with the name Kazia, or 0.12 per 100,000 residents. That placed it at #26,232 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 Kazia 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 Kazia?
In the 2020 Census sex table, Kazia leans strongly female. 345 people counted with this name were female (98.0%), compared with 7 male bearers (2.0%). 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 Kazia?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kazia is White at 42.7%. The next largest groups are Black (32.9%) and Asian/Pacific Islander (7.9%). 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 Kazia most often in the Census?
White is the largest reported group for people named Kazia in the 2020 Census, accounting for 42.7% (152 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 Kazia in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kazia a female name?
Yes, 100.0% of people registered as Kazia 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 Kazia still being used today?
Yes. The SSA still recorded Kazia 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 Kazia 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.
