Census
Kaysey in the 2020 Census
The 2020 Census recorded 201 people with the first name Kaysey, which placed it at #38,294 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 Kaysey
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaysey is White at 72.6%. The next largest groups are Black (8.5%) and Hispanic (8.0%). 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 Kaysey 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 Kaysey at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kaysey
The name Kaysey originates from the English language and has its roots in the medieval era. It is a variant spelling of the name Cassie, which is a diminutive form of the name Cassia. Cassia is derived from the Latin word "cassia," which refers to a type of aromatic bark used in ancient perfumes and incense.

It was primarily used as a feminine name, although there are instances of it being used for males as well. In the 14th century, a notable bearer of the name was Kaysey de Bois, a French noblewoman who lived in England during the reign of King Edward III.
During the Renaissance period, the name Kaysey gained popularity among the upper classes in England. One famous bearer of the name was Kaysey Howard, a courtier and cousin of Queen Elizabeth I, who lived from 1539 to 1596. Another notable figure was Kaysey Wentworth, an English writer and poet who lived from 1578 to 1637.
In the 17th century, the name Kaysey was associated with the Puritan movement in England and was sometimes given to children born during this period. One example is Kaysey Fleetwood, a Puritan minister and author who lived from 1612 to 1683.
In the 18th century, the name Kaysey became more widespread across various social classes in England. A notable bearer of the name was Kaysey Thorne, an English actress and playwright who lived from 1723 to 1786.

FAQ
Kaysey: questions and answers
How many people in the U.S. are named Kaysey?
Name Census puts the figure at roughly 143 living Americans. We arrive at this by taking every SSA birth registration for Kaysey 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 2,396,883 US residents.
Is Kaysey a common name?
We classify Kaysey as "Very Rare". It ranks above 69.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 148 babies have been registered with this name.
When was Kaysey most popular?
The single biggest year for Kaysey was 1993, when 16 babies received the name. The fact that the average living Kaysey is about 30 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Kaysey in the 2020 Census?
The published 2020 Census first-name tables recorded 201 people with the name Kaysey, or 0.07 per 100,000 residents. That placed it at #38,294 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 Kaysey 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 Kaysey?
In the 2020 Census sex table, Kaysey leans strongly female. 189 people counted with this name were female (93.6%), compared with 13 male bearers (6.4%). 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 Kaysey?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kaysey is White at 72.6%. The next largest groups are Black (8.5%) and Hispanic (8.0%). 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 Kaysey most often in the Census?
White is the largest reported group for people named Kaysey in the 2020 Census, accounting for 72.6% (146 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 Kaysey in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaysey a female name?
Yes, 100.0% of people registered as Kaysey 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 Kaysey still being used today?
Yes. The SSA still recorded Kaysey 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 Kaysey 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.
