Census
Izac in the 2020 Census
The 2020 Census recorded 682 people with the first name Izac, which placed it at #16,503 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 Izac
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Izac is Hispanic at 48.7%. The next largest groups are White (40.9%) and Two or More Races (3.7%). 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 Izac 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 Izac at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Izac
The name Izac is a variant spelling of the Hebrew name Isaac, which is derived from the biblical Hebrew phrase "yitzchak," meaning "he laughs" or "he will laugh." This name has its origins in the Hebrew Bible, specifically in the book of Genesis, where it is given to the son of Abraham and Sarah, who was born to them in their old age.
The name Isaac first appears in the biblical narrative in Genesis 17, when God promises Abraham that his wife Sarah will bear him a son, despite their advanced age. When Sarah overhears this promise, she laughs in disbelief, which prompts God to name the child Isaac, meaning "he laughs." The name is a reminder of the laughter of joy and wonder that accompanied Isaac's birth.
In the ancient Hebrew tradition, the name Isaac held great significance as it was associated with the covenant between God and Abraham. Isaac was the heir to God's promise to Abraham, and through him, the Israelite nation would be established. This biblical association has made the name Isaac, and its variant spellings like Izac, popular among Jewish and Christian communities throughout history.
One of the earliest recorded examples of the name Izac can be found in the writings of the medieval Jewish philosopher and physician, Maimonides (1135-1204 CE). He mentioned an individual named Izac in his work "Mishneh Torah," a comprehensive codification of Jewish law.
Another notable figure with the name Izac was Izac Goldsmid (1720-1795), a British financier and philanthropist of Jewish descent. He was a prominent member of the Goldsmid family, a wealthy Sephardic Jewish family in England, and was known for his contributions to the development of the Jewish community in London.
In the realm of literature, Izac Walton (1593-1683) was an English writer best known for his book "The Compleat Angler," a classic work on the subject of fly fishing. He is considered one of the fathers of the literary genre known as pastoral literature.
Izac ibn al-Shushtari (fl. 1288) was a Jewish poet and philosopher from Al-Andalus (modern-day Spain) who wrote in Arabic. He was known for his works on Jewish philosophy and his contributions to the development of the Judeo-Arabic literary tradition.
Lastly, Izac Swigger (1905-1971) was an American professional baseball player who played for the Philadelphia Athletics and the Boston Red Sox in the 1920s and 1930s. He was known for his defensive skills as an outfielder and his ability to hit for average during his Major League Baseball career.

FAQ
Izac: questions and answers
How many people in the U.S. are named Izac?
Name Census puts the figure at roughly 765 living Americans. We arrive at this by taking every SSA birth registration for Izac 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 448,045 US residents.
Is Izac a common name?
We classify Izac as "Very Rare". It ranks above 88.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 775 babies have been registered with this name.
When was Izac most popular?
The single biggest year for Izac was 2002, when 44 babies received the name. The fact that the average living Izac 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 Izac in the 2020 Census?
The published 2020 Census first-name tables recorded 682 people with the name Izac, or 0.23 per 100,000 residents. That placed it at #16,503 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 Izac 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 Izac?
In the 2020 Census sex table, Izac appears almost entirely male. Of the 674 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 Izac?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Izac is Hispanic at 48.7%. The next largest groups are White (40.9%) and Two or More Races (3.7%). 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 Izac most often in the Census?
Hispanic is the largest reported group for people named Izac in the 2020 Census, accounting for 48.7% (332 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 Izac in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Izac a male name?
Yes, 100.0% of people registered as Izac 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 Izac still being used today?
Yes. The SSA still recorded Izac 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 Izac 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.
