Origin
The surname Lademan has its origins in the Netherlands and dates back to the 16th century. It is believed to be derived from the Dutch word "laden," which means "to load" or "to carry," and the suffix "-man," indicating a person or occupation. This suggests that the name may have originally referred to someone involved in the loading or transportation of goods, such as a dock worker or a carter.
One of the earliest recorded instances of the name can be found in the Dutch province of Friesland, where a certain Douwe Laedeman was mentioned in a document from 1576. The name also appears in various spelling variations, such as Lademaan, Lademannus, and Lademan, reflecting the fluidity of surname spellings in that era.
In the 17th century, the Lademan name can be traced to the city of Amsterdam, where a notable figure named Jan Lademan (1592-1663) was a successful merchant and member of the city's affluent mercantile class. His son, Pieter Lademan (1622-1688), followed in his footsteps and became a prominent figure in the Dutch East India Company.
Another notable bearer of the Lademan surname was Gerrit Lademan (1705-1778), a Dutch artist known for his landscape paintings and etchings. His works can be found in various museums and art collections throughout the Netherlands and beyond.
During the 18th century, the Lademan family expanded their reach, with members settling in other parts of Europe and even venturing to the Dutch colonies in the East Indies (present-day Indonesia). One such individual was Willem Lademan (1756-1832), who served as a colonial administrator in Batavia (modern-day Jakarta).
In more recent times, the Lademan name has been associated with notable individuals such as Pieter Lademan (1876-1942), a Dutch politician and member of the House of Representatives, and Johanna Lademan (1902-1988), a renowned Dutch opera singer who performed on stages across Europe during the mid-20th century.
While the Lademan surname may not be as widespread as some other Dutch surnames, it has left a notable mark throughout history, with individuals bearing this name making contributions in various fields, from commerce and art to politics and the performing arts.
Demographics
Among Census respondents with the surname Lademan, the largest self-reported group is White at 91.3%. The next largest groups are Two or More Races (5.2%) and Hispanic (3.5%).
The bar chart below shows how Lademan 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 Lademan 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.
