Census
Siddhartha in the 2020 Census
The 2020 Census recorded 1,225 people with the first name Siddhartha, which placed it at #10,729 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 Siddhartha
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siddhartha is Asian/Pacific Islander at 87.0%. The next largest groups are Two or More Races (6.0%) and White (3.3%). 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 Siddhartha 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 Siddhartha at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Siddhartha
The name Siddhartha is of Sanskrit origin, tracing its roots back to ancient India and the Indic languages spoken on the Indian subcontinent. Derived from the Sanskrit words "siddha" meaning "accomplished" or "achieved," and "artha," meaning "meaning" or "wealth," the name roughly translates to "he who has attained his goals" or "he whose purpose has been achieved."
Siddhartha gained widespread recognition as the birth name of Gautama Buddha, the founder of Buddhism. Born around 563 BCE in Lumbini, present-day Nepal, the young prince was given the name Siddhartha at birth. According to Buddhist scriptures, he later renounced his privileged life to seek enlightenment, eventually becoming known as the Buddha, or "the Awakened One."
One of the earliest known references to the name Siddhartha can be found in the ancient Buddhist text, the Lalitavistara Sutra, which chronicles the life of the Buddha. This text, composed in Sanskrit, is believed to have been compiled between the 3rd century BCE and the 3rd century CE.
Throughout history, several notable figures have borne the name Siddhartha. One of the most renowned is Siddhartha Gautama, the Buddha himself, who lived from approximately 563 BCE to 483 BCE. Another prominent figure is Siddhartha Mukherjee, an Indian-American physician, biologist, and author, born in 1970, who won the Pulitzer Prize for his book "The Emperor of All Maladies: A Biography of Cancer."
In the 6th century CE, there was a Buddhist philosopher and scholar named Siddhartha Yogacara, who made significant contributions to the Yogacara school of Buddhist thought. Siddhartha Shankar Ray, an Indian politician and former Chief Minister of West Bengal, lived from 1920 to 2008 and was a prominent figure in the Indian independence movement.
Additionally, Siddhartha Basu, an Indian dramatist, and playwright who lived from 1956 to 2017, is renowned for his works that explored social and political themes in post-independence India. His plays, such as "Pratidwandi" and "Chakra," have been widely acclaimed and performed both in India and internationally.

FAQ
Siddhartha: questions and answers
How many people in the U.S. are named Siddhartha?
Name Census puts the figure at roughly 514 living Americans. We arrive at this by taking every SSA birth registration for Siddhartha 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 666,837 US residents.
Is Siddhartha a common name?
We classify Siddhartha as "Very Rare". It ranks above 84.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 523 babies have been registered with this name.
When was Siddhartha most popular?
The single biggest year for Siddhartha was 2015, when 33 babies received the name. The fact that the average living Siddhartha is about 19 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Siddhartha in the 2020 Census?
The published 2020 Census first-name tables recorded 1,225 people with the name Siddhartha, or 0.41 per 100,000 residents. That placed it at #10,729 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 Siddhartha 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 Siddhartha?
In the 2020 Census sex table, Siddhartha appears almost entirely male. Of the 1,223 people counted with this name, 99.1% were male and only a very small share were female. 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 Siddhartha?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Siddhartha is Asian/Pacific Islander at 87.0%. The next largest groups are Two or More Races (6.0%) and White (3.3%). 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 Siddhartha most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Siddhartha in the 2020 Census, accounting for 87.0% (1,066 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 Siddhartha in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Siddhartha a male name?
Yes, 100.0% of people registered as Siddhartha in the SSA data are male. 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 Siddhartha still being used today?
Yes. The SSA still recorded Siddhartha 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 Siddhartha 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.
