Origin
The surname LACOSTE has its origins in France, specifically the southern region of Languedoc. It is believed to have emerged around the 12th or 13th century, derived from the Old French term "la coste," which translates to "the hill" or "the slope." This suggests that the name may have initially referred to individuals residing on or near a hillside or sloping terrain.
One of the earliest recorded instances of the LACOSTE surname can be found in the Livre des Fiefs de la Sénéchaussée de Carcassonne, a document dating back to the 13th century. This record provides a glimpse into the presence of individuals bearing this surname in the Carcassonne region during that era.
In the 15th century, there are references to a nobleman named Jean de LACOSTE, who served as a knight and military commander during the Hundred Years' War. His contributions to the French cause were documented in various historical accounts from that period.
During the 16th century, the LACOSTE surname gained prominence in the region of Béarn, located in southwestern France. Notable figures from this era include Pierre de LACOSTE, a renowned jurist and legal scholar who served as the President of the Parliament of Navarre, born in 1530 and died in 1601.
In the 17th century, the LACOSTE family established themselves as prominent landowners and vineyard proprietors in the Languedoc region. One notable figure was Jacques de LACOSTE, born in 1620, who played a significant role in the development of the local wine industry and was highly regarded for his expertise in viticulture.
Another famous bearer of the LACOSTE surname was the French painter and engraver, Robert LACOSTE, who lived from 1741 to 1806. He was renowned for his landscape paintings and was recognized as a member of the prestigious Académie Royale de Peinture et de Sculpture in Paris.
As the LACOSTE surname spread throughout France and beyond, it underwent various spelling variations, such as LACOSTRE, LACOUSTE, and LACOUSTÈRE, reflecting regional linguistic differences and adaptations.
Demographics
Among Census respondents with the surname Lacoste, the largest self-reported group is White at 80.9%. The next largest groups are Black (9.7%) and Hispanic (5.5%).
The bar chart below shows how Lacoste 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 Lacoste 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.
