Origin
The surname Siddiqi has its roots in the Arabic language and is derived from the word "Siddiq," which means "truthful" or "sincere."

It is believed that the name originated during the early Islamic period, when the Arabic language and culture had a significant influence on the region.
The name Siddiqi is often associated with individuals who claim descent from the Prophet Muhammad's closest companion, Abu Bakr Siddiq, who was known for his unwavering truthfulness and loyalty. Abu Bakr Siddiq was the first caliph of the Islamic empire and played a crucial role in the spread of Islam.
One of the earliest recorded references to the name Siddiqi can be found in historical texts and manuscripts from the 11th and 12th centuries, during the reign of the Delhi Sultanate in India.

Another prominent figure was Syed Ismail Siddiqui (1880-1944), an Indian Muslim philosopher, and theologian who contributed significantly to the intellectual discourse of his time. He was a leading advocate of Islamic modernism and sought to reconcile traditional Islamic teachings with modern scientific thought.

Demographics
Among Census respondents with the surname Siddiqi, the largest self-reported group is Asian/Pacific Islander at 85.0%. The next largest groups are Two or More Races (6.9%) and White (6.1%).
The bar chart below shows how Siddiqi 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 Siddiqi surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Siddiqi (2000, 2010, 2020).
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.
