Census
Katielynn in the 2020 Census
The 2020 Census recorded 306 people with the first name Katielynn, which placed it at #29,088 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.

The bar chart below shows how people with the first name Katielynn 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 Katielynn at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Katielynn
The given name Katielynn is a modern English name that combines the names Katie and Lynn. The name Katie is a diminutive form of the name Katherine, which is derived from the Greek name Aikaterine. Aikaterine is composed of the Greek elements "katharos" meaning "pure" and "heiros" meaning "sacred" or "consecrated to God." The name Katherine was introduced to England after the Norman Conquest in 1066 and became popular among English royalty and nobility.
The name Lynn has its origins in several different ancient languages. It could be derived from the Celtic word "linn" meaning "lake" or "pool," or from the Old English word "linn" meaning "linden tree." It may also have originated from the Old German name "Linden" or the Old Norse name "Lina." The name Lynn was initially a surname but later became a popular given name, especially as a middle name.
While the exact origin of the combined name Katielynn is unclear, it likely emerged as a creative fusion of the names Katie and Lynn in the late 20th century or early 21st century. The name Katielynn does not appear to have any significant historical references or mentions in ancient texts or religious scriptures.
One of the earliest recorded examples of the name Katielynn is Katielynn Randolph, an American student who tragically lost her life in the Sandy Hook Elementary School shooting in 2012. Another notable individual with the name Katielynn is Katielynn Fiero, an American actress born in 1996, known for her roles in various television shows and films.
Throughout history, there have been several notable individuals with the name Katie or Katherine, such as:
1. Katherine of Aragon (1485-1536), the first wife of King Henry VIII of England.
2. Katherine Parr (1512-1548), the sixth and final wife of King Henry VIII.
3. Katharine Hepburn (1907-2003), an American actress known for her iconic roles in films like "The Philadelphia Story" and "The African Queen."
4. Katherine Graham (1917-2001), an American publisher who led The Washington Post during the Watergate scandal.
5. Katherine Johnson (1918-2020), an African American mathematician who made significant contributions to NASA's space program.
While the name Katielynn is a relatively modern combination, it carries elements from ancient languages and cultures, reflecting the diverse linguistic influences on English names.

FAQ
Katielynn: questions and answers
How many people in the U.S. are named Katielynn?
Name Census puts the figure at roughly 334 living Americans. We arrive at this by taking every SSA birth registration for Katielynn 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 1,026,211 US residents.
Is Katielynn a common name?
We classify Katielynn as "Very Rare". It ranks above 80.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 343 babies have been registered with this name.
When was Katielynn most popular?
The single biggest year for Katielynn was 2006, when 20 babies received the name. The fact that the average living Katielynn is about 26 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Katielynn in the 2020 Census?
The published 2020 Census first-name tables recorded 306 people with the name Katielynn, or 0.10 per 100,000 residents. That placed it at #29,088 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 Katielynn 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 Katielynn?
In the 2020 Census sex table, Katielynn appears almost entirely female. Of the 311 people counted with this name, 99.7% 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 Katielynn?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Katielynn is White at 86.9%. The next largest groups are Two or More Races (4.9%) and Hispanic (3.9%). 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 Katielynn most often in the Census?
White is the largest reported group for people named Katielynn in the 2020 Census, accounting for 86.9% (266 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 Katielynn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Katielynn a female name?
Yes, 100.0% of people registered as Katielynn 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 Katielynn still being used today?
Yes. The SSA still recorded Katielynn 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 Katielynn 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.
