Origin
Meaning and history of Kaustav
Kaustav is a Sanskrit name that originated in India during ancient times. It is derived from the word "Kaustuva," which means "a precious gem or jewel." The name is often associated with the sacred stone called the Kaustubha mani, which is believed to be a divine gemstone worn by the Hindu god Vishnu.
The Kaustubha mani is mentioned in various ancient Hindu scriptures, including the Puranas and the Mahabharata. In the Mahabharata, the epic describes the Kaustubha mani as a precious gem that was obtained by Lord Vishnu during the mythical churning of the ocean (Samudra Manthan).
One of the earliest recorded examples of the name Kaustav can be found in the Sanskrit literature of ancient India, where it was used as a name for individuals believed to possess exceptional qualities or virtues akin to a precious gem.
Throughout history, several notable individuals have borne the name Kaustav. One of the earliest recorded was Kaustav Bhattacharya (1016-1090 CE), a renowned Indian mathematician and astronomer from the Pala Empire in Bengal. He made significant contributions to the field of mathematics and astronomy, including the development of new methods for calculating planetary positions.
Another notable figure was Kaustav Chatterji (1887-1967), a prominent Indian revolutionary and politician who played a crucial role in the Indian independence movement against British colonial rule. He was a member of the Anushilan Samiti, a revolutionary organization dedicated to achieving India's freedom through armed struggle.
In more recent times, Kaustav Mukherjee (1939-2020) was a celebrated Indian classical musician and exponent of the Sitar. He was awarded the prestigious Sangeet Natak Akademi Award in 1997 for his contributions to Indian classical music.
Kaustav Chakraborty (born 1975) is a contemporary Indian film director and screenwriter known for his critically acclaimed works in Bengali cinema, such as "Prohor" and "Muktir Gaan."
Lastly, Kaustav Bagchi (born 1986) is a renowned Indian classical vocalist and composer who has received numerous awards and accolades for his contributions to Hindustani classical music, including the Ustad Bismillah Khan Yuva Puraskar in 2014.

FAQ
Kaustav: questions and answers
How many people in the U.S. are named Kaustav?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Kaustav 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 57,125,723 US residents.
Is Kaustav a common name?
We classify Kaustav as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Kaustav most popular?
The single biggest year for Kaustav was 2009, when 6 babies received the name. The fact that the average living Kaustav is about 17 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
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 Kaustav in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaustav a male name?
Yes, 100.0% of people registered as Kaustav 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 Kaustav still being used today?
Yes. The SSA still recorded Kaustav 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 Kaustav 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.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
