Origin
The surname Baldor has its origins in medieval England, dating back to the 12th century. It is believed to have derived from the Old English words "bald" and "dor," which together meant "the bold one." This name was likely bestowed upon a person with a brave or courageous demeanor.
One of the earliest recorded instances of the Baldor surname can be found in the Pipe Rolls of Gloucestershire from the year 1194, where a certain William Baldor is mentioned as a landowner. Another historical reference is found in the Patent Rolls of 1311, which document a John Baldor from Lincolnshire.
During the Middle Ages, the Baldor family seemed to have been concentrated in the counties of Gloucestershire, Lincolnshire, and Somerset. The name has also been spelled in various ways over the centuries, including Baldore, Bauldor, and Bawdor.
An interesting connection can be drawn between the Baldor surname and the character of Banquo from Shakespeare's famous play "Macbeth." Some scholars have speculated that the name "Banquo" may have been derived from the Old English word "bald," lending credence to the idea that the Baldor name was well-known during Shakespeare's time.
One notable figure with the Baldor surname was Sir Robert Baldor, a 14th-century knight who fought in the Hundred Years' War between England and France. Another individual of note was William Baldor, a prominent merchant and member of the Guild of Mercers in London during the 16th century.
In the 17th century, the Baldor family had established roots in the county of Wiltshire, as evidenced by the baptismal records of John Baldor in the parish of Warminster in 1632. Later, in the 18th century, a certain Thomas Baldor gained recognition as a skilled clockmaker in the city of Bristol.
The Baldor surname has also been associated with places like Baldor's Gate, a medieval gate in the city of Canterbury, Kent, and Baldor's Cliffe, a rocky promontory on the coast of Yorkshire. These place names likely derived from individuals bearing the Baldor surname who resided in or owned land in those areas.
Demographics
Among Census respondents with the surname Baldor, the largest self-reported group is Hispanic at 75.9%. The next largest groups are White (20.7%) and Asian/Pacific Islander (1.7%).
The bar chart below shows how Baldor 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 Baldor 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.
