Census
Iziah in the 2020 Census
The 2020 Census recorded 1,084 people with the first name Iziah, which placed it at #11,706 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 Iziah
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Iziah is Hispanic at 35.4%. The next largest groups are Black (27.3%) and White (21.8%). 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 Iziah 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 Iziah at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Iziah
The name Iziah is of Hebrew origin, derived from the biblical name Isaiah, which means "Yahweh is salvation" or "the Lord is salvation." The name gained popularity during the biblical times and was borne by the prophet Isaiah, who lived in the 8th century BC in ancient Judah.
The name Iziah is a variant spelling of the more common Isaiah, possibly influenced by the pronunciation of the name in different languages or regions. It first appeared in written records during the Middle Ages, primarily in European countries with Christian populations.
One of the earliest recorded individuals with the name Iziah was Iziah ben Solomon, a 12th-century Jewish scholar and philosopher from Spain. He was known for his work in the field of Kabbalah and his commentaries on various Jewish texts.
In the 16th century, Iziah Trusler was an English clergyman and author who wrote several religious works, including a commentary on the Book of Psalms published in 1590.
During the 18th century, Iziah Wilkinson was a noted English mathematician and astronomer. He made significant contributions to the field of celestial mechanics and was elected a Fellow of the Royal Society in 1768.
In the 19th century, Iziah John Greenwood was a British architect and surveyor who worked on various public buildings and infrastructure projects in the United Kingdom. He was born in 1812 and is known for his work on the design and construction of several railway stations.
Another notable figure with the name Iziah was Iziah Mudge, an American soldier and politician from Massachusetts. He served in the Continental Army during the American Revolutionary War and later served as a member of the Massachusetts State Legislature in the early 19th century.
While the name Iziah has been used throughout history, it has remained relatively uncommon compared to the more popular variant Isaiah. The name's biblical roots and connection to the prophet have likely contributed to its enduring presence, albeit in limited usage, across various cultures and time periods.

FAQ
Iziah: questions and answers
How many people in the U.S. are named Iziah?
Name Census puts the figure at roughly 1,291 living Americans. We arrive at this by taking every SSA birth registration for Iziah 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 265,495 US residents.
Is Iziah a common name?
We classify Iziah as "Rare". It ranks above 91.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 1,315 babies have been registered with this name.
When was Iziah most popular?
The single biggest year for Iziah was 2008, when 80 babies received the name. The fact that the average living Iziah is about 19 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Iziah in the 2020 Census?
The published 2020 Census first-name tables recorded 1,084 people with the name Iziah, or 0.36 per 100,000 residents. That placed it at #11,706 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 Iziah 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 Iziah?
In the 2020 Census sex table, Iziah leans strongly male. 1,054 people counted with this name were male (98.0%), compared with 21 female 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 Iziah?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Iziah is Hispanic at 35.4%. The next largest groups are Black (27.3%) and White (21.8%). 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 Iziah most often in the Census?
Hispanic is the largest reported group for people named Iziah in the 2020 Census, accounting for 35.4% (384 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 Iziah in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Iziah a male name?
Yes, 100.0% of people registered as Iziah 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 Iziah still being used today?
Yes. The SSA still recorded Iziah 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 Iziah 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.
