Origin
The surname Lasane is believed to have originated in France during the late 16th century. It is thought to be derived from the French phrase "la saine," which translates to "the healthy one." This suggests that the name may have been initially given as a descriptive nickname to someone of robust health or constitution.
One of the earliest recorded instances of the Lasane surname dates back to 1598 in the village of Châteauneuf-sur-Isère, located in the Drôme region of southeastern France. In a parish register from that year, a man named Pierre Lasane is listed as a resident of the village.
In the 17th century, the name appears to have spread to other parts of France. For example, in 1672, a Jacques Lasane is recorded as being born in the city of Bordeaux, which is situated in the southwestern region of the country.
During the 18th century, the Lasane surname can be found in various historical records throughout France. One notable individual from this time period was François Lasane, a merchant from the town of Nîmes who lived from 1723 to 1798.
As the name migrated and spread across Europe, it underwent various spelling variations. In some German-speaking regions, for instance, the name was adapted to "Lasahn" or "Lasahne."
Outside of France, one of the earliest known bearers of the Lasane surname was Hans Lasane, a Dutch merchant who was born in Amsterdam in 1657 and died there in 1732. Another prominent figure was the Italian playwright and poet, Antonio Lasane, who lived from 1675 to 1743 and was originally from the city of Venice.
In the 19th century, the Lasane name can be traced to several individuals of note. These include the French novelist and dramatist, Émile Lasane (1821-1892), and the German composer and conductor, Wilhelm Lasane (1836-1912).
As the centuries progressed, the Lasane surname continued to disperse across various countries and continents, carried by individuals and families who migrated from their ancestral homelands.
Demographics
Among Census respondents with the surname Lasane, the largest self-reported group is Black at 83.2%. The next largest groups are Two or More Races (7.9%) and White (6.0%).
The bar chart below shows how Lasane 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 Lasane 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.
