Origin
Meaning and origin of Blader
The surname Blader has its origins in the Netherlands and is believed to date back to the 16th century. It is derived from the Dutch word "blader," which means "leaf" or "foliage." This suggests that the name may have originally referred to someone who lived near a wooded area or worked with leaves or plants in some capacity.
One of the earliest known references to the Blader name can be found in the Leiden Archives, a collection of historical records from the Dutch city of Leiden. In 1587, a record mentions a person named Pieter Blader, who was a merchant in the city.
In the 17th century, the name appears in various Dutch records, including the Amsterdam Orphanage Records, which mention a child named Jan Blader in 1642. The Leiden Marriage Records also include a marriage between Joost Blader and Maria van Leeuwen in 1659.
The Blader name can be found in other parts of Europe as well. In Germany, there are records of a family named Blader living in the town of Erlangen in the early 18th century. One notable member of this family was Johann Christoph Blader, born in 1706, who was a Lutheran pastor and theologian.
In the 19th century, the Blader name appears in various American records, suggesting that members of the family had emigrated from Europe. One example is John Blader, born in 1822 in Pennsylvania, who served as a private in the Union Army during the American Civil War.
Another notable person with the Blader surname was Cornelis Blader, a Dutch painter who lived in the 17th century. He was known for his still life paintings and worked in the city of Leiden.
Overall, while not an extremely common surname, the Blader name has a long history and can be traced back to the Netherlands in the 16th century. Its meaning is closely tied to the Dutch word for "leaf" or "foliage," suggesting a connection to nature or the natural world.

The bar chart below shows how Blader 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 Blader surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
