Census
Londynn in the 2020 Census
The 2020 Census recorded 1,571 people with the first name Londynn, which placed it at #9,023 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.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Londynn is Black at 66.5%. The next largest groups are White (16.2%) and Two or More Races (8.5%). 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 Londynn 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 Londynn at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Londynn
The name Londynn is a modern invented name that appears to be a feminine variation of the place name London, the capital city of England. It does not have any direct linguistic roots in ancient languages or cultures.
The name London itself derives from the Roman settlement of Londinium, established around 43 AD. Londinium is thought to be a Latinized form of an older Celtic name, possibly meaning "navigable river" or "wild waters." The settlement was located along the River Thames, which would have been an important waterway for trade and transportation at the time.
There are no known historical references or recorded uses of the name Londynn prior to the late 20th century. It appears to have emerged as a creative spelling variation of London, likely inspired by the trend of adding extra letters or unique spellings to traditional names.
As a relatively new name, there are no famous historical figures specifically named Londynn. However, there are a few notable individuals with the traditional spelling of London throughout history:
London Williams (born 1997) is an American actress and singer, best known for her roles in the television series American Horror Story and Raven's Home.
London Fletcher (born 1975) is a former American football linebacker who played in the National Football League for 16 seasons.
London Breed (born 1974) is an American politician who currently serves as the 45th mayor of San Francisco, California.
London Keyes (born 1977) is an American former pornographic actress and radio personality.
London Calling is the name of a famous album released by the English punk rock band The Clash in 1979, which is considered one of the greatest albums in rock history.
While the name Londynn may be a recent invention, its connection to the historic city of London gives it a sense of cultural significance and ties to an important location in English and world history.

FAQ
Londynn: questions and answers
How many people in the U.S. are named Londynn?
Name Census puts the figure at roughly 3,002 living Americans. We arrive at this by taking every SSA birth registration for Londynn 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 114,175 US residents.
Is Londynn a common name?
We classify Londynn as "Rare". It ranks above 95.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 3,024 babies have been registered with this name.
When was Londynn most popular?
The single biggest year for Londynn was 2015, when 246 babies received the name. The fact that the average living Londynn is about 10 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Londynn in the 2020 Census?
The published 2020 Census first-name tables recorded 1,571 people with the name Londynn, or 0.52 per 100,000 residents. That placed it at #9,023 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 Londynn 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 Londynn?
In the 2020 Census sex table, Londynn leans strongly female. 1,548 people counted with this name were female (98.5%), compared with 24 male bearers (1.5%). 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 Londynn?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Londynn is Black at 66.5%. The next largest groups are White (16.2%) and Two or More Races (8.5%). 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 Londynn most often in the Census?
Black is the largest reported group for people named Londynn in the 2020 Census, accounting for 66.5% (1,045 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 Londynn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Londynn a female name?
Yes, 100.0% of people registered as Londynn 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 Londynn still being used today?
Yes. The SSA still recorded Londynn 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 Londynn 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.
