Origin
The surname LEJEUNE originated in France during the late medieval period. It derives from the French words "le jeune" meaning "the young," and was likely originally used as a nickname to distinguish the younger of two individuals with the same first name. The name spread throughout France, particularly in the northern and central regions.
One of the earliest recorded instances of the surname LEJEUNE appears in the Armorial Général of 1696, a registry of French nobility and landed gentry, where several LEJEUNE families from various provinces are listed. The LEJEUNE name can also be found in numerous parish records and census documents from the 17th and 18th centuries across France.
In the 14th century, a prominent LEJEUNE family resided in the town of Châlons-en-Champagne, located in the historical province of Champagne. Roger LEJEUNE (c. 1320 - 1392), a wealthy merchant and landowner from this family, played a significant role in the town's governance and economy.
During the Renaissance period, Jean LEJEUNE (1530 - 1596), a renowned French composer and music theorist, made significant contributions to the development of polyphonic music. His works were widely performed and studied throughout Europe.
Another notable figure was Marguerite LEJEUNE (1675 - 1755), a French novelist and playwright from Paris. Her novel "Les Aventures de Monsieur Robert Chevalier" was widely popular in its time and helped establish her reputation as a prominent female author in the 18th century.
In the 19th century, Louis LEJEUNE (1823 - 1896), a French military officer and historian, gained recognition for his works on Napoleon's campaigns and the Napoleonic Wars. His comprehensive accounts, based on extensive research and primary sources, are still regarded as valuable references.
The LEJEUNE surname also has a long-standing presence in the French-speaking regions of Belgium and Switzerland, where variations such as LEJENNE and LEJEUNNE can be found in historical records.
Demographics
Among Census respondents with the surname Lejeune, the largest self-reported group is White at 90.0%. The next largest groups are Two or More Races (3.4%) and Black (3.2%).
The bar chart below shows how Lejeune 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 Lejeune surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lejeune (2000, 2010, 2020).
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.
