Shanley in the 2020 Census
The 2020 Census recorded 533 people with the first name Shanley, which placed it at #19,699 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 Shanley
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Shanley is White at 74.9%. The next largest groups are Black (6.6%) and Asian/Pacific Islander (6.4%). 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 Shanley 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 Shanley at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Shanley
The given name Shanley originates from the Irish language and culture, with its roots tracing back to the medieval period. It is derived from the Gaelic surname Ó Seanálaigh, which means "descendant of Seanálach." Seanálach itself is a personal name composed of the elements "sean" (old) and a diminutive suffix, suggesting a meaning along the lines of "little old one" or "little ancient one."
Historically, the name Shanley was predominantly found in Ireland, particularly in the regions of Connacht and Leinster. It is believed to have been used as a personal name as early as the 12th century, though records from that era are scarce and incomplete.
One of the earliest documented mentions of the name Shanley can be found in the Annals of Ulster, a chronicle of medieval Irish history compiled by monks in the 15th century. The annals record the death of a notable figure named Shanley O'Donnell in the year 1413.
In the 16th century, a prominent Irish family bearing the surname Shanley played a significant role in the political and military affairs of the time. Patrick Shanley (1522-1591) was a notable figure who served as the Bishop of Leighlin and was involved in the Irish Confederate Wars.
As the name spread beyond Ireland, it found its way into other cultures and languages. In the late 18th century, the English poet and novelist Samuel Egerton Brydges (1762-1837) used the name Shanley for a character in one of his works, introducing it to a wider audience.
Other notable individuals named Shanley throughout history include:
1. John Shanley (1770-1837), an Irish-American soldier who fought in the War of 1812 and later became a prominent businessman in New York City.
2. Katharine Shanley (1819-1889), an Irish-American educator and pioneer in the field of women's education, who founded the Shanley School for Girls in New York City.
3. John Shanley (1869-1940), an American prelate of the Roman Catholic Church who served as the Bishop of Fargo, North Dakota.
4. James Shanley (1915-1996), an American playwright and screenwriter, known for his works such as "Danny and the Deep Blue Sea" and "Moonstruck," for which he received an Academy Award nomination.
5. John Patrick Shanley (born 1950), an American playwright, screenwriter, and director, best known for his play "Doubt: A Parable" and the film adaptation of the same name, for which he won the Pulitzer Prize for Drama and an Academy Award for Best Adapted Screenplay.

FAQ
Shanley: questions and answers
How many people in the U.S. are named Shanley?
Name Census puts the figure at roughly 458 living Americans. We arrive at this by taking every SSA birth registration for Shanley 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 748,372 US residents.
Is Shanley a common name?
We classify Shanley as "Very Rare". It ranks above 83.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 473 babies have been registered with this name.
When was Shanley most popular?
The single biggest year for Shanley was 1993, when 26 babies received the name. The fact that the average living Shanley is about 28 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Shanley in the 2020 Census?
The published 2020 Census first-name tables recorded 533 people with the name Shanley, or 0.18 per 100,000 residents. That placed it at #19,699 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 Shanley 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 Shanley?
In the 2020 Census sex table, Shanley leans strongly female. 453 people counted with this name were female (85.3%), compared with 78 male bearers (14.7%). 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 Shanley?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Shanley is White at 74.9%. The next largest groups are Black (6.6%) and Asian/Pacific Islander (6.4%). 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 Shanley most often in the Census?
White is the largest reported group for people named Shanley in the 2020 Census, accounting for 74.9% (399 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 Shanley in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Shanley a female name?
Yes, 100.0% of people registered as Shanley 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 Shanley still being used today?
Yes. The SSA still recorded Shanley 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 Shanley 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.
