Sydny in the 2020 Census
The 2020 Census recorded 379 people with the first name Sydny, which placed it at #25,119 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.

Ancestry and ethnicity for Sydny
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sydny is White at 62.3%. The next largest groups are Black (13.2%) and Hispanic (13.2%). 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 Sydny 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 Sydny at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Sydny
The name Sydny is derived from the Old English word "sid," meaning wide or extensive. It is believed to have originated as a place name referring to a broad valley or expansive meadow. The name first appeared in written records around the 8th century CE in the Anglo-Saxon region of Britain.
During the medieval period, the name Sydny was primarily used as a surname, often given to families residing in or near a wide valley or open field. One of the earliest recorded instances of the name as a given name dates back to the 13th century, when a nobleman named Sydny de Houghton was mentioned in the Domesday Book.
In the 16th century, the name gained popularity among Puritans, who favored names with biblical or virtuous meanings. They likely embraced Sydny as a reference to the expansive nature of God's creation or the vastness of spiritual enlightenment.
One notable bearer of the name was Sydny Parkinson (1545-1633), an English botanist and explorer who accompanied Captain James Cook on his voyage to the South Pacific. Parkinson's detailed illustrations and descriptions of the flora and fauna encountered during the expedition made significant contributions to the field of natural history.
Another historical figure with the name Sydny was Lady Sydny Morgan (1783-1859), a Welsh philanthropist and social reformer. She was instrumental in establishing schools and hospitals for the poor in her native Wales and advocated for better working conditions for factory workers during the Industrial Revolution.
In the realm of literature, Sydny Shelton (1917-2007) was an acclaimed American novelist and short story writer. Her poignant works, often set in the American South, explored themes of racial prejudice, family dynamics, and the complexity of human relationships.
The name Sydny also found its way into the world of sports with Sydny Crosby (born 1987), a Canadian professional ice hockey player and captain of the Pittsburgh Penguins. Crosby is widely regarded as one of the greatest players of his generation and has won numerous accolades, including three Stanley Cup championships.
While the name Sydny has experienced ebbs and flows in popularity over the centuries, it has remained a distinctive and enduring choice, carrying with it a sense of expansiveness, exploration, and the boundless potential of the human spirit.

FAQ
Sydny: questions and answers
How many people in the U.S. are named Sydny?
Name Census puts the figure at roughly 263 living Americans. We arrive at this by taking every SSA birth registration for Sydny 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 1,303,248 US residents.
Is Sydny a common name?
We classify Sydny as "Very Rare". It ranks above 77.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 270 babies have been registered with this name.
When was Sydny most popular?
The single biggest year for Sydny was 2000, when 33 babies received the name. The fact that the average living Sydny is about 27 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Sydny in the 2020 Census?
The published 2020 Census first-name tables recorded 379 people with the name Sydny, or 0.13 per 100,000 residents. That placed it at #25,119 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 Sydny 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 Sydny?
In the 2020 Census sex table, Sydny leans strongly female. 358 people counted with this name were female (92.3%), compared with 30 male bearers (7.7%). 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 Sydny?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sydny is White at 62.3%. The next largest groups are Black (13.2%) and Hispanic (13.2%). 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 Sydny most often in the Census?
White is the largest reported group for people named Sydny in the 2020 Census, accounting for 62.3% (236 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 Sydny in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sydny a female name?
Yes, 100.0% of people registered as Sydny 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 Sydny still being used today?
Yes. The SSA still recorded Sydny 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 Sydny 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.
