Ac in the 2020 Census
The 2020 Census recorded 994 people with the first name Ac, which placed it at #12,493 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 Ac
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Ac is Black at 43.8%. The next largest groups are White (32.9%) and Hispanic (11.8%). 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 Ac 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 Ac at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Ac
The name Ac has its origins in the ancient Mesopotamian language of Akkadian, spoken by the Assyrians and Babylonians as early as the 3rd millennium BCE. It is derived from the Akkadian word "akku," which means "to be pleasing" or "to be agreeable." This suggests that the name may have originally been given to individuals with a pleasant or agreeable demeanor.
One of the earliest recorded instances of the name Ac can be found in the epic of Gilgamesh, one of the oldest known literary works in human history, dating back to around 2100 BCE. In the epic, Ac is mentioned as a minor character, a warrior in the army of Gilgamesh, the legendary king of Uruk.
During the Neo-Assyrian period, which spanned from the 9th to the 7th century BCE, the name Ac gained popularity among the Assyrian nobility and ruling class. Several notable figures from this era bore the name, including Ac-shar-ibni, a high-ranking military commander who served under King Sennacherib in the 7th century BCE.
As the Akkadian language and culture spread throughout the ancient Near East, the name Ac also found its way into other regional languages and cultures. In ancient Persia, for instance, there are records of an influential courtier named Ac-barzin, who lived during the reign of Darius the Great in the 5th century BCE.
Moving forward in time, the name Ac also appears in various ancient Greek and Roman texts, likely adopted from the earlier Mesopotamian cultures. One noteworthy individual was Ac-metus, a Greek philosopher and mathematician who lived in the 5th century BCE and is credited with several important contributions to the field of geometry.
In the later centuries of the Roman Empire, the name Ac was occasionally used by members of the aristocracy and upper classes. One such example is Ac-cius Strabo, a Roman poet and grammarian who lived in the 1st century BCE and is known for his works on Latin prosody and metrics.
Throughout the Middle Ages and into the Renaissance period, the name Ac remained in use, although it was relatively uncommon compared to other names of the time. One notable figure was Ac-cursius, an Italian jurist and legal scholar from the 13th century, who made significant contributions to the study and interpretation of Roman law.

FAQ
Ac: questions and answers
How many people in the U.S. are named Ac?
Name Census puts the figure at roughly 65 living Americans. We arrive at this by taking every SSA birth registration for Ac 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 5,273,144 US residents.
Is Ac a common name?
We classify Ac as "Very Rare". It ranks above 58.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 119 babies have been registered with this name.
When was Ac most popular?
The single biggest year for Ac was 1993, when 10 babies received the name. The fact that the average living Ac is about 39 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Ac in the 2020 Census?
The published 2020 Census first-name tables recorded 994 people with the name Ac, or 0.33 per 100,000 residents. That placed it at #12,493 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 Ac 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 Ac?
The 2020 Census sex table shows Ac on both sides of the split. Of the 999 people counted with this name, 796 were male (79.7%) and 203 were female (20.3%). 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 Ac?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Ac is Black at 43.8%. The next largest groups are White (32.9%) and Hispanic (11.8%). 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 Ac most often in the Census?
Black is the largest reported group for people named Ac in the 2020 Census, accounting for 43.8% (435 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 Ac in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Ac a male name?
Yes, 100.0% of people registered as Ac 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 Ac still being used today?
Yes. The SSA still recorded Ac 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 Ac 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.
