Origin
Meaning and origin of Vaidya
The surname Vaidya has its origins in India and can be traced back to ancient times. It is derived from the Sanskrit word 'vaidya,' which means a physician or a doctor. The name was initially used to denote those who practiced Ayurvedic medicine, a traditional system of medicine that has been prevalent in India for thousands of years.
The earliest recorded instances of the surname Vaidya can be found in various Hindu scriptures and ancient texts, where it was used to refer to individuals who were renowned for their expertise in Ayurvedic healing practices. One of the earliest known references to the name appears in the Atharva Veda, one of the four Vedas, which dates back to around 1000 BCE.
During the medieval period, the Vaidya surname became more widespread across the Indian subcontinent. Several historical accounts and records mention individuals bearing this surname, particularly in regions where Ayurvedic medicine had a strong presence. For instance, the Vaidya family of Varanasi, a renowned center of learning and culture, is believed to have had a long lineage of Ayurvedic practitioners dating back to the 12th century.
Some notable individuals with the surname Vaidya throughout history include Narahari Vaidya (1543-1624), a renowned Ayurvedic physician and scholar who authored several influential texts on the subject. Bapalal Vaidya (1848-1919) was a prominent social reformer and educationist who played a significant role in promoting female education in India. Ramakrishna Vaidya (1850-1920) was a pioneering photographer and one of the first individuals to establish a commercial photography studio in India.
In more recent times, Karan Vaidya (1911-1987) was a distinguished Indian archaeologist and historian who made significant contributions to the study of ancient Indian history and culture. Manindra Vaidya (born 1969) is a renowned computer scientist and mathematician, known for his groundbreaking work in computational complexity theory.
While the surname Vaidya is predominantly found in India, it has also spread to other parts of the world due to migration and diaspora communities. However, its roots can be traced back to the ancient Indian tradition of Ayurvedic medicine and the esteemed status accorded to those who practiced this healing art.

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 Vaidya surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
