Census
Izaiah in the 2020 Census
The 2020 Census recorded 8,806 people with the first name Izaiah, which placed it at #2,670 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 Izaiah
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Izaiah is Hispanic at 48.5%. The next largest groups are White (19.2%) and Black (18.0%). 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 Izaiah 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 Izaiah at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Izaiah
The name Izaiah is a variant of the Hebrew name Isaiah, which means "salvation of the Lord" or "the Lord is salvation." The name can be traced back to the biblical prophet Isaiah, who lived in the 8th century BC in the ancient Kingdom of Judah.
The Book of Isaiah in the Old Testament of the Bible is attributed to the prophet Isaiah, who was a prominent figure during the reign of King Hezekiah. Isaiah's teachings and prophecies played a significant role in the development of Judaism and Christianity.
The name Izaiah gained popularity during the Middle Ages, particularly among Jewish communities. One of the earliest recorded individuals with this name was Izaiah ben Abraham, a 12th-century Jewish philosopher and commentator from Spain.
In the 16th century, Izaiah ben Judah Gershon, a Jewish scholar and grammarian, made notable contributions to the study of Hebrew grammar and linguistics.
During the 17th century, Izaiah Horowitz, a renowned Kabbalist and Talmudic scholar from Prague, wrote several influential works on Jewish mysticism and ethics.
In the 19th century, Izaiah Berlin, a Russian-British philosopher and historian, was widely recognized for his contributions to the study of political theory and the concept of liberty.
Another notable individual with the name Izaiah was Izaiah Davenport, an African American Baptist minister and abolitionist who lived in the 19th century and advocated for the abolition of slavery in the United States.
Over the centuries, the name Izaiah has been used across various cultures and communities, although it remains closely tied to its Hebrew origins and biblical associations.

FAQ
Izaiah: questions and answers
How many people in the U.S. are named Izaiah?
Name Census puts the figure at roughly 14,323 living Americans. We arrive at this by taking every SSA birth registration for Izaiah 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 23,930 US residents.
Is Izaiah a common name?
We classify Izaiah as "Uncommon". It ranks above 98.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 14,463 babies have been registered with this name.
When was Izaiah most popular?
The single biggest year for Izaiah was 2009, when 742 babies received the name. The fact that the average living Izaiah is about 14 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Izaiah in the 2020 Census?
The published 2020 Census first-name tables recorded 8,806 people with the name Izaiah, or 2.92 per 100,000 residents. That placed it at #2,670 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 Izaiah 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 Izaiah?
In the 2020 Census sex table, Izaiah appears almost entirely male. Of the 8,798 people counted with this name, 99.5% 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 Izaiah?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Izaiah is Hispanic at 48.5%. The next largest groups are White (19.2%) and Black (18.0%). 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 Izaiah most often in the Census?
Hispanic is the largest reported group for people named Izaiah in the 2020 Census, accounting for 48.5% (4,274 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 Izaiah in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Izaiah a male name?
Yes, 99.9% of people registered as Izaiah 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 Izaiah still being used today?
Yes. The SSA still recorded Izaiah 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 Izaiah 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.
