Origin
The surname Cesar has its origins in ancient Rome, derived from the Latin cognomen "Caesar," which was initially a personal name. The name itself is believed to have originated from the Latin word "caesaries," meaning "hair" or "head of hair," possibly referring to someone with a full head of hair.
The name gained prominence during the reign of Julius Caesar, the renowned Roman dictator and military leader who lived from 100 BC to 44 BC. After his death, the name Caesar became a title bestowed upon Roman emperors, and it eventually evolved into a surname.
Cesar can be traced back to the Domesday Book, a comprehensive survey of land and property commissioned by William the Conqueror in 1086. The name appears in various spellings, such as "Cesar" and "Cesare," indicating its early presence in England.
One of the earliest recorded individuals with the surname Cesar was Pietro Cesare (1270-1326), an Italian jurist and legal scholar from Bologna, known for his contributions to canon law and his work on the Decretals of Pope Gregory IX.
Another notable figure was Cesare Borgia (1475-1507), an Italian nobleman, politician, and cardinal, who was the illegitimate son of Pope Alexander VI. Cesare gained infamy for his ruthless pursuit of power and his involvement in various intrigues and conflicts during the Renaissance period.
In England, Sir Julius Caesar (1558-1636) was a prominent figure who served as a judge and held the position of Master of the Rolls, one of the most influential legal positions in the country at the time.
The surname Cesar also has connections to various place names, such as Cesarea in modern-day Israel, which was founded by Herod the Great and named in honor of the Roman emperor Augustus Caesar.
Another historical figure bearing the name Cesar was Cesare Lombroso (1835-1909), an Italian criminologist and physician who is known for his influential but controversial theories on the biological origins of criminal behavior, which were later discredited.
Throughout history, the surname Cesar has been borne by individuals from various walks of life, including artists, writers, politicians, and scholars, reflecting its enduring legacy and diverse origins.
Demographics
Among Census respondents with the surname Cesar, the largest self-reported group is Black at 46.6%. The next largest groups are Hispanic (26.2%) and White (20.9%).
The bar chart below shows how Cesar 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 Cesar 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.
