Census
Kaydi in the 2020 Census
The 2020 Census recorded 323 people with the first name Kaydi, which placed it at #28,012 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 Kaydi
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaydi is White at 64.7%. The next largest groups are Hispanic (16.1%) and Black (6.8%). 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 Kaydi 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 Kaydi at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kaydi
The name Kaydi is believed to have its origins in the ancient Persian language, dating back to the 6th century BCE. It is derived from the Persian word "kaydi," which means "gentle" or "kind." The name was initially popular among the Persians, who lived in the region that is now modern-day Iran.
During the height of the Persian Empire, the name Kaydi was often associated with nobility and royalty. Some historical records suggest that there were several Persian princesses and queens who bore this name, although their exact identities have been lost to history.
As the Persian Empire expanded its influence across the Middle East and parts of Europe, the name Kaydi began to spread to other cultures and regions. It was adopted by various ethnic groups, including the Armenians and the Kurds, who lived in the areas that are now parts of Turkey, Syria, and Iraq.
One of the earliest recorded instances of the name Kaydi can be found in the ancient Armenian epic poem, "The Daredevils of Sassoun," which dates back to the 8th century CE. In this epic, Kaydi is the name of a heroic warrior who played a significant role in the battles against the invading Arab forces.
Throughout history, there have been several notable individuals who bore the name Kaydi. One of the earliest recorded was Kaydi al-Baghdadi (1050-1123), an influential Persian scholar and philosopher who made significant contributions to the fields of mathematics and astronomy during the Islamic Golden Age.
Another prominent figure was Kaydi Burhan al-Din (1345-1398), a Persian mystic and poet who was known for his spiritual writings and his influence on the Sufi tradition. His works, including the famous "Masnavi," have been widely studied and celebrated throughout the centuries.
In the 16th century, there was a Kurdish princess named Kaydi Khatun, who was renowned for her beauty and her patronage of the arts and literature. She was married to the Ottoman Sultan Selim I and played a significant role in the cultural exchange between the Ottoman Empire and the Persian world.
More recently, in the 20th century, there was a Turkish writer and women's rights activist named Kaydi Aydemir (1913-1995), who was known for her novels and her advocacy for gender equality and social justice.
While the name Kaydi may not be as common today as it once was, it remains a part of the rich cultural heritage of the Persian and Middle Eastern regions, carrying with it a sense of gentleness, kindness, and historical significance.

FAQ
Kaydi: questions and answers
How many people in the U.S. are named Kaydi?
Name Census puts the figure at roughly 288 living Americans. We arrive at this by taking every SSA birth registration for Kaydi 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 1,190,119 US residents.
Is Kaydi a common name?
We classify Kaydi as "Very Rare". It ranks above 78.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 294 babies have been registered with this name.
When was Kaydi most popular?
The single biggest year for Kaydi was 2011, when 19 babies received the name. The fact that the average living Kaydi is about 23 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Kaydi in the 2020 Census?
The published 2020 Census first-name tables recorded 323 people with the name Kaydi, or 0.11 per 100,000 residents. That placed it at #28,012 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 Kaydi 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 Kaydi?
In the 2020 Census sex table, Kaydi appears almost entirely female. Of the 317 people counted with this name, 100.0% were female and only a very small share were male. 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 Kaydi?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaydi is White at 64.7%. The next largest groups are Hispanic (16.1%) and Black (6.8%). 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 Kaydi most often in the Census?
White is the largest reported group for people named Kaydi in the 2020 Census, accounting for 64.7% (209 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 Kaydi in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaydi a female name?
Yes, 100.0% of people registered as Kaydi 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 Kaydi still being used today?
Yes. The SSA still recorded Kaydi 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 Kaydi 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.
