One of the earliest known individuals with this surname was Abu Bakr Muhammad ibn Yahya al-Saidian, a renowned Persian scholar and poet who lived in the 9th century.
During the medieval period, the surname SAIDIAN was particularly prevalent in the city of Saidian, which was located in the present-day province of Khorasan in northeastern Iran. This city was known for its rich cultural heritage and was a center of learning and scholarship during that time.
In the 12th century, a notable figure with the surname SAIDIAN was Sadr al-Din al-Saidian, a Persian philosopher and astronomer who made significant contributions to the field of astronomy and wrote several treatises on celestial mechanics.
The surname SAIDIAN also has a connection to the Safavid dynasty, which ruled over Persia (modern-day Iran) from the 16th to the 18th century. During this period, there were several members of the royal court who bore the surname SAIDIAN, indicating its association with nobility and prominence.
Another notable individual with the surname SAIDIAN was Mirza Abdul Karim SAIDIAN, a 19th-century Persian diplomat and scholar who served as the ambassador of Persia to several European countries, including France and Russia.

The bar chart below shows how Saidian 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 Saidian 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.
