Origin
The surname UDANI is believed to have originated in India, tracing its roots back several centuries. It is thought to be derived from the Sanskrit word "udana," which means "arising" or "rising." This suggests that the name may have been associated with a particular region, occupation, or social status that involved a sense of elevation or ascension.
One of the earliest recorded instances of the UDANI surname can be found in historical texts from the region of present-day Rajasthan, dating back to the 16th century. During this period, the name appears to have been prevalent among certain communities, particularly those engaged in trade or administrative roles.
In the 17th century, a notable figure bearing the UDANI name was Govind UDANI, a renowned scholar and poet who gained prominence for his contributions to Sanskrit literature. His works, which included poetic compositions and philosophical treatises, were widely celebrated and helped to preserve the cultural heritage of the region.
Another prominent UDANI was Jagat Singh UDANI, a military leader who lived in the late 18th century. He played a significant role in the campaigns against the Maratha Empire, earning a reputation for his strategic acumen and bravery on the battlefield.
The 19th century saw the rise of Karan UDANI, a influential social reformer and educator. Karan dedicated his life to promoting education and advocating for the rights of marginalized communities. His efforts laid the foundation for many progressive movements in the region.
In more recent times, the UDANI surname has been associated with several notable figures in various fields. One such individual was Rani UDANI, a pioneering environmentalist and conservationist who worked tirelessly to protect the natural habitats of endangered species in India.
Another prominent UDANI was Vijay UDANI, a renowned architect whose innovative designs and sustainable building practices earned him international recognition. His works have left an indelible mark on the architectural landscape of the country.
While the UDANI surname may have originated in India, it has since spread to various parts of the world, carried by individuals and families who have migrated and established themselves in different regions. However, its roots remain deeply embedded in the rich cultural heritage of the Indian subcontinent.
Demographics
Among Census respondents with the surname Udani, the largest self-reported group is Asian/Pacific Islander at 84.4%. The next largest groups are Two or More Races (8.1%) and White (4.4%).
The bar chart below shows how Udani 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 Udani 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.
