Census

Siena in the 2020 Census

The 2020 Census recorded 8,227 people with the first name Siena, which placed it at #2,812 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 Siena

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siena is White at 65.3%. The next largest groups are Hispanic (19.1%) and Two or More Races (9.1%). 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 Siena 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 Siena at the time of the 2020 Census, not any inherent property of the name itself.

Origin

Meaning and history of Siena

The name Siena has its roots in the Italian language and is believed to have originated from the city of Siena in the Tuscany region of Italy. The city's name is derived from the ancient Etruscan word "Saina," which means "ancient one" or "ancient settlement."

Siena, the city, is steeped in history and has been mentioned in various ancient texts and records. It was an important center of trade and commerce during the Middle Ages and was a prominent rival to Florence in the region. The city's name has been documented in medieval chronicles and historical accounts.

The earliest recorded use of the name Siena as a personal name dates back to the 13th century in Italy. During this time, it was not uncommon for families in the region to name their children after the city or town they were from.

One of the earliest and most notable individuals with the name Siena was Siena di Enrichetto, a medieval Italian painter who lived from around 1285 to 1355. She is considered one of the first documented female artists in the history of Italian art.

Another notable figure with the name Siena was Saint Siena (1347-1380), an Italian Dominican tertiary who is venerated as a saint in the Catholic Church. She was known for her mystic visions and her efforts to promote peace during the Western Schism.

In the 16th century, Siena Padovani (1531-1589) was an Italian composer and musician who was active in the Venetian Republic during the Renaissance period.

Fast forward to the 19th century, Siena Berlusconi (1825-1899) was an Italian painter and sculptor who was known for her works in the Neoclassical style.

More recently, Siena Castellon (1941-2018) was a French fashion designer and entrepreneur who founded her own successful fashion label in the 1970s.

These are just a few examples of notable individuals throughout history who have borne the name Siena, a name with deep roots in Italian culture and history.

FAQ

Siena: questions and answers

How many people in the U.S. are named Siena?

Name Census puts the figure at roughly 10,475 living Americans. We arrive at this by taking every SSA birth registration for Siena 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 32,721 US residents.

Is Siena a common name?

We classify Siena as "Uncommon". It ranks above 97.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10,590 babies have been registered with this name.

When was Siena most popular?

The single biggest year for Siena was 2018, when 496 babies received the name. The fact that the average living Siena is about 14 years old gives you a rough sense of which era contributed the most bearers who are still alive today.

How common was Siena in the 2020 Census?

The published 2020 Census first-name tables recorded 8,227 people with the name Siena, or 2.72 per 100,000 residents. That placed it at #2,812 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 Siena 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 Siena?

In the 2020 Census sex table, Siena appears almost entirely female. Of the 8,218 people counted with this name, 99.8% 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 Siena?

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siena is White at 65.3%. The next largest groups are Hispanic (19.1%) and Two or More Races (9.1%). 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 Siena most often in the Census?

White is the largest reported group for people named Siena in the 2020 Census, accounting for 65.3% (5,370 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 Siena in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Siena a female name?

Yes, 100.0% of people registered as Siena 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 Siena still being used today?

Yes. The SSA still recorded Siena 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 Siena 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. You can read the full calculation on our methodology page.
