Origin
The surname Krishnan is of Indian origin, specifically from the Tamil speaking regions of southern India. It dates back to ancient times and is derived from the Sanskrit word "Krishna" which means dark or black.
The name Krishnan was originally an honorific title bestowed upon Vaishnavite Brahmins and other upper-caste Hindus who revered Lord Krishna, an avatar of the god Vishnu. Over time, it evolved into a surname used by various communities across South India.
One of the earliest recorded references to the name Krishnan can be found in the ancient Tamil literary works of the Sangam period, which dates back to the 3rd century BCE to the 3rd century CE. Several prominent poets and scholars from this era bore the name, including Krishnan Ravi, a celebrated Tamil poet and scholar from the 2nd century CE.
During the medieval period, the name Krishnan was associated with several influential figures in South Indian history. One notable example is Krishnan Raya, a 16th-century ruler of the Vijayanagara Empire, who was known for his patronage of art and architecture.
In the 18th century, Krishnan Sastri, a renowned scholar and philosopher from Tamil Nadu, gained widespread recognition for his works on Hindu philosophy and theology.
Another prominent bearer of the name was Krishnan Iyer, a 19th-century social reformer and educator from Kerala, who played a crucial role in establishing modern educational institutions in the region.
In more recent times, Krishnan Nair Shantakumaran Nair, a renowned Kathakali artist and choreographer from Kerala, has contributed significantly to the preservation and promotion of this classical Indian dance form.
Other notable individuals with the surname Krishnan include Krishnan Pandalai, a celebrated Indian writer and journalist from the early 20th century, and Krishnan Rajeshwari, a renowned Carnatic music vocalist and recipient of the Padma Bhushan, one of India's highest civilian honors.
Demographics

The bar chart below shows how Krishnan bearers 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 surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Krishnan surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
