Origin
The surname Qamar has its origins in the Arabic language, tracing its roots back to the Middle East and the Islamic world. It is derived from the Arabic word "qamar," which translates to "moon" or "lunar." This name likely emerged during the height of the Islamic Golden Age, a period spanning from the 8th to the 13th centuries.
One of the earliest recorded instances of the surname Qamar can be found in the historical annals of the Abbasid Caliphate, which ruled a vast empire stretching from North Africa to Central Asia between the 8th and 13th centuries. The name appears in various manuscripts and chronicles from this era, often associated with scholars, poets, and prominent figures of the time.
In the 10th century, a renowned Persian astronomer and mathematician named Abu'l-Wafa' al-Buzjani, whose full name was Muhammad ibn Muhammad ibn Yahya ibn Isma'il al-Qamar al-Buzjani, made significant contributions to the field of trigonometry and the development of astronomical instruments. His works were widely studied and referenced by subsequent generations of scholars.
During the 12th century, a prominent Sufi mystic and poet named Jalaluddin Rumi, whose full name was Jalal ad-Din Muhammad Rumi, mentioned the name Qamar in his famous poetic works, such as the Masnavi. Rumi's poetry often drew upon celestial imagery, including references to the moon, which may have been inspired by the name's meaning.
In the 14th century, a Persian scholar and historian named Hamdullah Mustaufi Qazvini, whose full name was Hamdullah ibn Abi Bakr ibn Nasr al-Qamar al-Qazwini, authored a renowned geographical work titled "Nuzhat al-Qulub" (Delight of the Hearts), which provided detailed descriptions of various regions and cities across the Islamic world.
Another notable figure bearing the surname Qamar was Mir Qamaru'd-Din Minai, a 16th-century Persian calligrapher and artist renowned for his intricate and beautiful works of miniature painting and calligraphy. His works are considered masterpieces of the Safavid era and are preserved in various museums and collections around the world.
While the surname Qamar has its roots in the Middle East and the Islamic world, it has since spread to other regions through migration and cultural exchange. Over the centuries, variations in spelling and pronunciation have emerged, reflecting the diverse linguistic and cultural influences encountered by those bearing this surname.
Demographics
Among Census respondents with the surname Qamar, the largest self-reported group is Asian/Pacific Islander at 83.6%. The next largest groups are White (9.1%) and Two or More Races (3.7%).
The bar chart below shows how Qamar 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 Qamar 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.
