Origin
The surname Bidart originates from the Basque region of northern Spain and southern France, dating back to the medieval period. It is derived from the Basque words "bide" meaning "way" or "path" and "arte" meaning "between," suggesting a connection to a place situated between paths or roads.
One of the earliest recorded instances of the name Bidart can be found in the Codex de Roda, a 10th-century Aragonese manuscript, which mentions a person named Didacus Bidart. This indicates that the name was already in use during that time in the Basque regions of Spain.
In the 13th century, the name appeared in various documents from the Navarre region, such as the Cartulario de la Catedral de Pamplona, which recorded land transactions and legal matters involving individuals with the surname Bidart.
The name Bidart is closely tied to the town of the same name in the Basque Country of France, located near the city of Biarritz. This town likely derived its name from the same Basque root words, suggesting that the surname may have originated from this particular area.
One notable individual with the surname Bidart was Juan Bidart, a Spanish soldier and explorer who accompanied Hernán Cortés during the conquest of Mexico in the 16th century. He played a significant role in the Spanish colonization efforts and is mentioned in several historical accounts from that period.
Another prominent figure was Pedro Bidart, a Basque navigator and explorer who sailed with Juan de la Cosa on the Spanish expeditions to the Americas in the late 15th and early 16th centuries. He is credited with mapping and charting several regions along the Caribbean coast.
In the 17th century, the name Bidart appeared in records from the Basque provinces of Gipuzkoa and Bizkaia, with references to individuals such as Martín Bidart, a prominent merchant, and Catalina Bidart, a landowner and benefactor of the local church.
During the 18th century, the Bidart family produced several notable figures, including Miguel Bidart, a Basque writer and philosopher whose works explored themes of Basque culture and identity, and Juana Bidart, a renowned painter known for her portraits and religious works.
In the 19th century, José Bidart, a Basque politician and advocate for regional autonomy, played a significant role in the political landscape of the Basque Country, working to preserve the region's cultural heritage and rights.
Demographics
Among Census respondents with the surname Bidart, the largest self-reported group is White at 68.6%. The next largest groups are Hispanic (31.4%).
The bar chart below shows how Bidart 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 Bidart 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.
