Origin
The surname Vafai has its origins in Persia, now known as Iran, and can be traced back to the 10th century. It is derived from the Persian word "vafa," which means loyalty or faithfulness. The name is believed to have been initially given to individuals who exhibited these traits or were closely associated with someone who did.
During the Safavid dynasty (1501-1736), the Vafai name gained prominence in the region of Isfahan, a major cultural and economic center of the time. Records from this period show several influential families bearing the surname, including merchants, scholars, and high-ranking officials.
One of the earliest recorded mentions of the Vafai name can be found in the "Tarikh-e Beyhaghi," a historical chronicle written in the 11th century by Abu'l-Fazl Beyhaqi. The text references a certain Vafai who served as a courtier during the reign of the Ghaznavid Sultan Mahmud.
In the 13th century, a prominent figure named Shams al-Din Muhammad Vafai established a Sufi order known as the Vafaiyya. This order gained a significant following in parts of Iran and Central Asia, and its influence likely contributed to the further spread and recognition of the Vafai name.
One notable bearer of the Vafai surname was Mirza Salman Vafai (1584-1661), a Persian poet and calligrapher who lived during the Safavid era. His works, including the renowned "Tazkirat al-Shu'ara," have been widely studied and celebrated in the Persian literary tradition.
Another historical figure was Mirza Mohammad Reza Vafai (1810-1885), a prominent Iranian statesman and diplomat who served as the Prime Minister of Persia during the reign of Naser al-Din Shah Qajar.
In the 20th century, the Vafai name gained international recognition through the work of Reza Vafai (1910-1995), an Iranian artist and calligrapher who was celebrated for his contributions to modern Persian calligraphy.
Sadegh Vafai (1923-2008) was a renowned Iranian physician and professor who made significant contributions to the field of hematology and was widely respected for his academic and medical achievements.
Additionally, Nasr Vafai (born 1942) is a notable Iranian painter and sculptor whose works have been exhibited globally and are part of various prestigious collections.
While the Vafai surname has its roots in Persia, it has since spread to other parts of the world, particularly through immigration and diaspora communities. However, its history and origins remain closely tied to the rich cultural heritage of Iran and the Persian language.
Demographics
Among Census respondents with the surname Vafai, the largest self-reported group is White at 79.3%. The next largest groups are Two or More Races (9.9%) and Asian/Pacific Islander (4.5%).
The bar chart below shows how Vafai 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 Vafai 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.
